Neobythitoides n. gen. (Figs. 1-4) Type species. Neobythitoides serratus n. sp. Remarks The lack of a chin-barbel, the presence of cycloid scales and the posterior position of the ventral-fins place this ophidiid genus in the subfamily Neobythitinae, which according to Nielsen et al. (1999) contains 38 genera. Table 1 shows a comparison between the genera that have the following characters in common: A well developed opercular spine, two median basibranchial tooth patches, two ventral-fin rays placed below preopercle, more than six developed gill rakers, all pectoral-fin rays joined and one lateral line. The table indicates that Neobythitoides is most similar to Neobythites, which also is supported by overall similarity. However, a phylogenetic analysis has not been performed. Diagnosis and similarity Neobythitoides is defined by the following combination of characters (those of Neobythites are mentioned in brackets): Posterior margin of preopercle with 10-15 soft serrations (Fig. 2) and no spines (margin without serration and with 0-3 spines), snout almost twice as long as horizontal diameter of pigmented eye (snout equal to or slightly longer than eye), horizontal eye window 2.5-2.7 % SL (3.7-6.0 % SL), two median and in the holotype (Fig. 3) also a pair of small basibranchial tooth patches (two median basibranchial tooth patches), 10-11 developed rakers on anterior gill arch (6-34), sagittal otolith (Fig. 4) with undivided sulcus (sulcus divided into a caudal and osteal part - sagittae from 49 out of 50 known Neobythites species were examined) and sulcus-length in percentage of sagitta-length 50-55 (65-85). Etymology Neobythitoides refers to the resemblance to the genus Neobythites., Published as part of J��rgen G. Nielsen & Yoshihiko Machida, 2006, Neobythitoides serratus, a new bathyal genus and species from the East China Sea (Teleostei, Ophidiidae)., pp. 63-68 in Zootaxa 1227 on pages 64-66

A new genus and species of ophidiid fishes, Ventichthys biospeedoi, is described based on two male specimens caught in the French BIOSPEEDO expedition to the South East Pacific Rise. They were caught by a baited trap at the hydrothermal vent site Oasis ( 17 degrees 25.38' S, 113 degrees 12.29' W) at 2586 m. The new genus differs from all of the 48 known ophidiid genera by its thick skin, posteriorly placed and enlarged kidneys, broad head, and 4 lateral lines. The most similar genera are Benthocometes and Petrotyx having a blunt snout, one basibranchial tooth patch, granular teeth, and no free pectoral fin rays. Remarks on the ecology of the new species are based on analysis of video documents taken in situ by a submarine Nautile.

Brotula barbata (Bloch, 1801) Reference material. Accra, February 1930 (Irvine 41)— BMNH 1930.8.26.76 (one: 390 mm SL). Distribution. Coast of tropical West Africa from southern Senegal to Angola. Also known from the tropical western Atlantic (Nielsen et al., 1999). On average about 450 tonnes of this species are caught in the region each year (FAO, 2000), making it a significant fishery species., Published as part of Edwards, A. J., Gill, A. C. & Abohweyere, P.

Fifty-five specimens of pink cusk-eel, Genypterus brasiliensis Regan, 1903 (Osteichthyes: Ophidiidae) collected from the coastal zone of the State of Rio de Janeiro, Brazil (approx. 21-23 degrees S, 41-45 degrees W), from September 2000 to January 2001, were necropsied to study their parasites. All fish were parasitized by one or more metazoan. Fourteen species of parasites were collected. G. brasiliensis is a new host record for nine parasite species. The larval stages of cestodes and the nematodes were the majority of the parasite specimens collected, with 38.4% and 36.5%, respectively. Cucullanus genypteri was the dominant species with highest prevalence and/or abundance. The parasites of G. brasiliensis showed the typical overdispersed pattern of distribution. Six parasite species showed correlation between the host's total body length and prevalence and abundance. Host sex did not influence prevalence and parasite abundance of any parasite species. The mean diversity in the infracommunities of G. brasiliensis was H= 0.364 +/- 0.103, with correlation with the host's total length and without differences in relation to sex of the host. One pair of adult endoparasites (C. genypteri and A. brasiliensis) showed positive covariations between their abundances. Negative association or covariation was not found. Differences between the qualitative and quantitative aspects of the parasite community of G. brasiliensis from Rio de Janeiro and Argentina suggest the existence of two population stocks of pink cusk-eel in the South America Atlantic Ocean.

Entre septiembre de 2000 y enero de 2001 fueron necropsiados 55 especimenes de congrio rosado, G. brasiliensis procedentes de la costa del estado del Río de Janeiro (21-23° S, 41-45° W), Brasil. Todos los congrios examinados estaban parasitados por C. genypteri, colectándose un total de 1.312 especimenes; con abundancia media de 23,8 ± 26,7. Cucullanus genypteri presentó un típico patrón de distribución sobredispersa o contagiosa. La abundancia de C. genypteri presentó correlación positiva con el tamaño corporal del hospedador. El sexo de los peces no influenció en la abundancia del parásito. Between September of 2000 and January of 2001, 55 specimens of pink cusk-eel, Genypterus brasiliensis Regan, 1903 were captured from the coastal of the State of Rio de Janeiro, Brazil (aprox. 21-23° S, 41-45° W), and necropsied to study their cucullanid nematode. All fishes were parasitized for Cucullanus genypteri Sardella, Navone & Timi, 1997. A total of 1312 parasites were collected, with average of 23.8/fish. The cucullanid nematode of G. brasiliensis showed a typical pattern of distribution. Cucullanus genypteri showed an increase in abundance in relation to the host size. The sex of host did not influence the abundance of C. genypteri.

En aguas colombianas existen tres especies de Brotula. La de mayor talla e importancia pesquera es B. clarkae Hubbs, 1944, ampliamente distribuida en el Pacífico americano y explotada en las costas suroccidentales colombianas por su abundancia y por alcanzar más de 1 m y de 8 kg. Brotula ordwayi Hildebrand and amp; Barton, 1949, es el segundo miembro del género presente en el Pacífico americano, pero es relativamente rara, de pequeña talla (menos de 50 cm) y se le conoce únicamente de Costa Rica, Gorgona y Talára (Perú). En el Atlántico sólo existe una especie, B. barbata (Schneider, 1801), la cual es conocida del Caribe colombiano a partir de dos ejemplares procedentes de Santa Marta. Three species of Brotula are known from Colombian waters. Brotula clarkae Hubbs, 1944, the largest and the most important species to fisheries, is widely distributed in the American Pacific, being exploited in southwest Colombia where it ls abundant and reaches more than 1 m and 8 kg. Brotula ordwayi Hildebrand and amp; Barton, 1949, is the second species known from the American Pacifico It is relatively rare and small, reaching less than 50 cm, and known only from Costa Rica, Gorgona and Talara (Perú). In the Atlantic there is only one species, B. barbata (Schneider), known from two specimens from Santa Marta, Colombian Caribbean.

The bathyal genus Benthocometes (Teleostei: Ophidiidae) is revised based on 29 specimens from the Atlantic Ocean and the Mediterranean Sea and one from off NW Australia. Examination of the Atlantic and Mediterranean material confirmed the synonomizing of the three Atlantic species, B. robustus, B. armatum and B. muraenolepis. The Australian specimen represents a new species, B. australiensis, differing from B. robustus in e.g. the number of long rakers on the anterior gill arch, the form of the palatine dentition and the predorsal and upper jaw lengths.

13. Dicrolene introniger, new species. Several specimens of a species of Dicrolene were obtained from Stations 325 and 326. Body moderately compressed, its dorsal and anal outlines approaching at an equal angle the horizontal axis, and tapering to a narrow point, which forms the base of the caudal fin. Scales small, about 110 rows between the branchial opening and the tail, and about '21 transverse rows counting upward and forward obliquely from the origin of the anal. The lateral line rudimentary, running near the base of the dorsal fin at a distance from it less than the diameter of the eye, and apparently becoming obsolete on the posterior third of the body. Body height one sixth of standard length. Head somewhat comprcsscd, with llattisli upper surface, which is encroached upon by the upper margins of the orbit. At the posterior upper margin of each orbit is a strong spine pointing backward and upward; a long sharp spine at the upper angle of the operculum, its exposed portion as long as half the diameter of the eye. Preoperculum, on its lower posterior border, with three equidistant spines much weaker than that of the operculum. Large muciferous cavities in the bones of the head: a row of large cavities extending backward from the upper angle of the orbit, and continuous with those on the lateral line. Mouth larsje: its cleft considerablv longer than half the length of the head, and the maxillary extending behind the vertical from the posterior margin of the orbit. The posterior portion of the maxillary much expanded, its width at the end equal to three fourths the diameter of the eye. L T pon its expanded tip are scales. Eye large, one fourth as long as head, and as wide as the interorbital space. Length of head one fifth standard length. Dorsal fin inserted at a distance from the snout equal to two ninths the length of the body. Anal inserted under the vertical from the 25th or 26th dorsal ray. The height of the dorsal and anal fins is about equal to the diameter of the eye. Their bases extend almost to the insertion of the caudal. The caudal is composed of six or seven rays: its length equal to half the distance from the snout to the insertion of the dorsal. The ventrals inserted almost under, but slightly posterior to, the posterior limb of the preoperculum, in length about equalling the upper jaw. Pectorals inserted close to the branchial aperture; the eight lower rays being free and much prolonged, the longest and most anterior being nearly one third as long as the body, and more than three times as long as the contiguous posterior ray of the normally-constructed portion of the fin, which is, however, about equal to the last of the free rays. The free portion of the pectoral being longer, and composed of fewer rays, than the normal portion, the fish has the appearance of bearing two pectoral fins of the same general shape, the lower of which is the longer. The length of the normal portion of the fin is contained about four times in the length of the body. Radial formula: D. 100; A. about 85; C. 6 or 7; V. \; P. 19 -j- 7 or 8.

Acanthonus armatus. The head of this remarkable fish appears of an extraordinary thickness compared with the thin and compressed trunk and tail; it is very broad across the frontal region, and not much longer than high, the small eye being much nearer to the end ot the snout than to the gill-opening. The snout would be truncated in front; but its upper portion projects, terminating in two short acute spines. The large mouth is slightly oblique, the maxillary extending backwards beyond the middle of the length of the head. The jaws are equal in front. Two sharp edges run along each ramus of the mandible, to receive between them a wide muciferous channel. North of New Guinea, 1075 fathoms., Published as part of G��nther, Albert C. L.
