that found in rocks supposed to be of the same age in Newfoundland ; 

 in fact, the arenera are all such as occur at the base of the Cambrian 

 in New Brunswick [ProtoJenus zone). A difference of age, however, 

 is -to be inferred from the fact that the species are all different and 

 new. Of Braohiopods there are — Lingulella, two species; Lepto- 

 bolus (?), two sp. ; Oholus (subgen. Falceobolus, n.subgen.), one sp. ; 

 Acrothele, one sp. ; Acrotreta, one sp. Of Ostracods there are — 

 Bradoria (n.gen.), three sp. ; Schnidtella, two sp. Four plates of 

 figures representing these species accompany the article. 



X. — Studies on Ca3ibrian Faunas : No. 3, Upper Cambrian Fauna 

 of Mount Stephen, etc. ; No. 4, Fragments of the Cambrian 

 Faunas of Newfoundland. Also The Etcheminian Fauna of 

 Smith Sound, Newfoundland. By O. F. Matthew, D.Sc, LL.D. 

 Trans. Koy. Soc. Canada, ser. ii, vol. v (1899), sect. 4, p. 39. 



THESE articles on the early Palaeozoic faunas of the eastern part 

 of Canada and Newfoundland and on that of Mount Stephen in 

 British Columbia serve to extend and broaden our knowledge of the 

 species of that early time in America. Dr. Matthew, on a careful 

 review of the Mount Stephen fauna, concludes that it may be 

 regarded as equivalent to the Peltura fauna of N.W.Europe. Eleven 

 genera of trilobites are recognized, — Ogygia (Ogygopsis), BaiTiy- 

 tiriscus, Zacanthoides, Neoleniis (n.gen. with 5 n.spp.), Ptyclioparia, 

 Dorypyge, Agnostus, Corynexochus, DoUchometopiis, Onjctocephalus, 

 and Conocephalites. Two new genera and four new species of 

 Hyolithidge are described. This problematic group of animals is, 

 in accordance with the views of Pelseneer and Holm, absolutely 

 removed from the Pteropoda or any other Mollusca, and is referred by 

 Dr. Matthew to the Annelida, a conclusion which is at any rate more 

 consistent with their predominance at so low a geological horizon. 



Under ' Study ' No. 4, a variety of forms from several horizons 

 of the Cambrian of Newfoundland is described. Raphistoma (?) 

 Kelliensis, n.sp., is an early type of a Pleurotomarioid Gasteropod. 

 Several worm-burrows and trails are described, and a large Hyolithes. 

 Among the trilobites is a Jllicrodisciis ; the Agrauloid forms are 

 represented by Strenuella (subgen.) ; two new species of Miomacea 

 are described ; one new Avalonia, and a fine Metadoxides. The 

 Conocoryphinffi are re-classified, C. trilineatus as subgen. Atops, and 

 Erinnys vemdosa, Salt., as SJ. (Harpides) breviceps, Ang. 



The third article gives the fauna of a set of beds described by the 

 author as a separate terrane, lying beneath the beds that carry the 

 well-known fauna of Paradoxides and the less-known fauna of 

 Protolenus, which underlies it. This fauna, to which we have 

 referred in the preceding note, is remarkable for the prevalence of 

 Hyolithidee and primitive types of Gasteropods and Braohiopods. 

 In this article the new Gasteropod genus Randomia is described, and 

 the following new species : Kutorgina, one sp. ; Randomia, one sp. ; 

 Platyceras, three sp. ; Modiolopsis, one sp. ; TJrotheca, one sp. ; 

 ■ Helenia, one sp. ; HyoUthellus, one sp. ; Orthotheca, four sp. ;. 

 Hyolithes, one sp. ; Aptychopsis, one sp. 

 . The articles are accompanied by eight plates of figures.
