part of Yancouver Island aad adjacent coasts, in 1885, fossils apparently 

 of Triassic age wero collected by Dr. Dawson at Robson Island, and on 

 the east side of "Winter Harbour in Forward Inlet, at Alexander Har- 

 bour on G-aliano Island, in a bay five miles and a half west of Cape 

 Commerell, and on Hernando Island in the Strait of Georgia. Finally, 

 a series of fossils, which are probably also of Triassic age and which 

 arc remarkably well-preserved, was obtained by 3Ir. E. G. MoCounell, 

 in ISST, on the Liard Elver, about twenty-five and thirty miles below 

 Devil's Portage, or, approximately in latitude 59° 16', and longitude 

 125° 35'. 



The stratigraphical relations of the rocks from which the fossils 

 here reported on were obtained, will be found described in the Eeports 

 of the Survey for each of the years in which the fossils wero collected. 



All the specimens collected at these localities are in the Museum of 

 the Survey, and the collection of the Triassic fossils of British Colum- 

 bia now contained therein consists of three species of braehiopoda, five 

 of lamellibranchiata, one of gasteropoda and eight of cephalopoda, 

 besides the undeterminable fragments of Fentacrinites already referred 

 to. Of these, only four (viz., Terebratula Humboldtensis, Monotis sub- 

 circularis, Halobia Lonimeli and Arcestes Gabbi,) can be identified with 

 pi'eviously described species, the rest being apparently new to science. 



The present paper will consist of a systematic list of the whole of 

 the species at present in the Museum of the Survey from the forma- 

 tion and province indicated in its title, with descrijjtions and figures of 

 those that are believed to be new. For critical and valuable euffo-es- 

 tions in regard to some of the latter, and for the description of a sup- 

 posed new genus of cephalopoda, the writer is indebted to Professor 

 Alpheus Hyatt.

Plate 17, fig. 1. 



Shell transversely subelliptical, broadly rounded in front and obtusely 

 subangular in the middle behind, a little broader than long, and broad- 

 est at the midlength : cardinal angles rounded : surface of the valves 

 marked with angular and rather coarse radiating plications. 



Ventral valve moderately convex, most prominent on each of the 

 outer boundaries of the angular and well-defined mesial sinus, which is
