Chesser (2013) intended to introduce a justified emendation to Icterus bullockii under Article 32.5.1 of the Code (ICZN 1999), because the name honors both William Bullock, Sr., and William Bullock, Jr. However, the correction bullockorum is "incorrect" and therefore is an unjustified emendation (Article 33.2.3). Under the assumption that the name Bullock was latinized (cf. Article 31.1.1) to Bullockius ( bullocki – + the nominative case ending – us ) and therefore that the name bullockii comprises the stem bullocki – + the genitive case ending – i , the justified correction bullockiorum is required.

William Bullock was an Englishman who owned the Egyptian Hall (also known as the London Museum or Bullock’s Museum) at Piccadilly in London, a museum opened in 1812 to display his collection of antiquities, artifacts, and natural history specimens. Following the sale of Bullock’s collection in 1819, the Egyptian Hall served as an exhibition space. Bullock and his son, William Bullock, Jr., both enthusiastic naturalists, travelled in Mexico in 1822–1823, spending some six months together collecting natural history specimens and other artifacts for exhibition and investigating mining and other business opportunities (Costeloe 2006). The elder Bullock returned to London with the collections in 1823, but his son, while ostensibly managing the silver mine his father had purchased in Temascaltepec, outside of Mexico City, continued to travel in Mexico and collect specimens, often in the company of German naturalist Ferdinand Deppe (Costeloe 2006). William Bullock, Sr., meanwhile prepared the Mexican collection for exhibition at the Egyptian Hall. Twin exhibitions on ancient and modern Mexico opened, with much fanfare, in April 1824, and were a great success, remaining open until September 1825 (Costeloe 2006). Afterwards, the contents of the exhibitions were dispersed via auction, but not before Bullock had made the bird specimens available to English naturalist William Swainson for “recording this portion of his discoveries” (Swainson 1827: 365).

Spoonbills (genus Platalea) are a small group of wading birds, generally considered to constitute the subfamily Plataleinae (Aves: Threskiornithidae). We reconstructed phylogenetic relationships among the six species of spoonbills using variation in sequences of the mitochondrial genes ND2 and cytochrome b (total 1796 bp). Topologies of phylogenetic trees reconstructed using maximum likelihood, maximum parsimony, and Bayesian analyses were virtually identical and supported monophyly of the spoonbills. Most relationships within Platalea received strong support: P. minor and P. regia were closely related sister species, P. leucorodia was sister to the minor-regia clade, and P. alba was sister to the minor-regia-leucorodia clade. Relationships of P. flavipes and P. ajaja were less well resolved: these species either formed a clade that was sister to the four-species clade, or were successive sisters to this clade. This phylogeny is consistent with ideas of relatedness derived from spoonbill morphology. Our limited sampling of the Threskiornithinae (ibises), the putative sister group to the spoonbills, indicated that this group is paraphyletic, in agreement with previous molecular data; this suggests that separation of the Threskiornithidae into subfamilies Plataleinae and Threskiornithinae may not be warranted.
