Cyriacotheriidae are a family of unusual small-bodied pantodonts known from the Paleocene of the Western Interior of North America. Cyriacotheriids possess a suite of dental characters similar to that of pantodonts (e.g., molar dilambdodonty, lingual molar hypoconulids), as well as several divergent features (e.g., molarized premolars, strong molar conules) that have been interpreted as "dermopteran-like." The unusual combination of pantodont and dermopteran-like characters, combined with a limited fossil record, has made attempts at understanding the broader relationships of Cyriacotheriidae difficult. This paper reports on a new genus and two new species of cyriacotheriids from the Paleocene of Alberta, Canada, with both species significantly older than those of the only previously described cyriacotheriid, Cyriacotherium. Collectively, the dentitions of these new taxa exhibit derived characters seen in Cyriacotherium (e.g., robust molar conules, strong molar dilambdodonty) in addition to a number of plesiomorphies seen in more basal pantodonts (e.g., conspicuous molar entoconids, deep premolar ectoflexus) and, importantly, posterior premolars that are weakly molariform and non-dilambdodont. A phylogenetic analysis of the new cyriacotheriid, basal pantodonts, dermopterans, and dermopteran-like eutherians resulted in Cyriacotheriidae nesting within a monophyletic Pantodonta. The results strengthen previous hypotheses regarding the pantodont affinities of the family, and suggest that the dermopteran-like features seen in the more derived Cyriacotherium were acquired convergently. Although the discovery of new cyriacothcriids sheds light on the evolutionary history of the family, it cannot resolve the ongoing questions of pantodont origins; nonetheless, their discovery in strata of early Paleocene age indicates that significant parts of the evolutionary history of Cyriacotheriidae, and North American pantodonts more generally, have yet to be discovered.

Since their introduction in 1973, comprehensive land claims (CLC) agreements have become important mechanisms for Aboriginal peoples to achieve their political, social, cultural, and economic goals. Although the literature on CLC negotiations is a rich and varied one, it has tended to ignore the role that municipal governments have on influencing negotiation outcomes. This lacuna is surprising since a number of treaty negotiations in the Yukon Territory and BC involve lands located in major municipalities. This paper develops a theoretical framework for understanding the influence that municipal governments can have on treaty negotiation outcomes. Using a case study of the Kwanlin Dün First Nation treaty negotiations in the Yukon Territory, we find that institutional and milieu factors are important. However, leadership was the most important and decisive factor. [ABSTRACT FROM AUTHOR]

Poplack, Zentz and Dion (PZD; Poplack, Zentz & Dion, 2011, this issue) examine the often unquestioned assumption that the existence of preposition stranding (PS) in Canadian French is linked to the presence of a contact situation with English in the North American context. Although this issue has been the topic of previous research from a syntactic perspective (Bouchard, 1982; Vinet, 1979, 1984), to my knowledge, it has never been explored using variationist sociolinguistic methods applied to a large corpus of spontaneous speech, with emphasis on code-switchers as potential agents of contact-induced change.

Two lichenicolous species are discussed: the recently described Unguiculariopsis nephrornae, which occurs on Nephroma species in Canada, Fennoscandia, North America and Russia, is combined into Protounguicularia; and Hyalopeziza rapax sp. nov. is described from Pseudocyphellaria crocata in Alaska. In discussing generic placements, it is concluded that the species now known as Qua transiens is better accommodated in Protounguicularia and the species is combined into that genus. Attention is drawn to variability in general appearance of P. nephromatis, particularly the occurrence of both superficial and erumpent apothecia in the same species. [ABSTRACT FROM AUTHOR]
