THE DEVONIAN. 



Eobert Bell (15) in his Eeport G of the Annual Report of the Geo- 

 logical Survey of Canada for 188G, notes the occurrence of fossiliferous 

 limestones in the valley of the At-ta-wa-j)ish-kat and Albauy Rivers. 

 These fossils were submitted to Prof. J. F. Whiteaves, the paleontolo- 

 gist of the Survey, who identified them as indicating Devonian faunas 

 (pp. 27, G-33, G). The species reported are mainly corals and brachio- 

 pods; Mr. Whiteaves thinks them of a Lower Devonian horizon. No 

 new species are defined. 



S. Calvin (21) records the fact of the appearance of a coral-bearing 

 zone intercalated between two brachiopod zones in the Hamilton rocks 

 in western Ontario, and remarks uj)on the different form assumed by 

 the Sjnrifera mucronata of the first and third zones. The same author 

 (20) describes a new genus and species of tubicolar Annelida from the 

 Hamilton period, Roberts's Ferry, Iowa ; these are StrcptincUtes (gen. 

 nov.), p. 27, and 8. acervularuv (sp. nov.), p. 27. No illustrations are 

 given. 



J. M. Clarke (28) gives an account of the Annelid teeth from the De- 

 vonian of Ontario County, New York. Twenty-nine specimens of these 

 teeth are figured, twenty-two of which express varieties of form ap- 

 pearing in the Black Shale of Naples, and are regarded as varieties 

 of the form described by Hinde under the name of Polygnathus duhius. 

 The other forms are referred to the genera Arahellites, Frioniodus, 

 <Enonites, and Ennicites. These forms have heretofore generally gone 

 under the name of " Conodonts." 



James Hall (97) adds another volume to the valuable contributions 

 to the paleontology of New York State. This volume (vi) contains the 

 (Corals and Bryozoa [Polyzoa] from the Lower Helderberg, Upper Hel- 

 derberg, and Hamilton groups. There are described one hundred and 

 three species from the Lower Helderberg, one hundred and fifty-four 

 from the Upper Helderberg, g,ij4 P,u§ Ijuudred and twenty-one from the
