fossils seems to indicate for tliem the age of the Middle Cretaceous; 

 aud in some respects tliey remind one of the Gosaii formation of Enroi)e. 

 The author describes the new genus CoraUiochnma ; with C. orcutti as its 

 type, he places it among the Chamidw. The following new species are 



also described : Trochus {Oxystele) euryostomiis, Nerita f, Cerithium^ 



P'dlingi, G. totium-sanctorum. Solarium wallalense.

From the Laramie of the Willow Creek series the author describes 



Unio Alhcrtensis. From the -Saint Marj-'s River series and lower portion 



of the Laramie generally he describes the following new si^ecies: Ano- 



mia perstrigosa, Corhicula obliqua, CorhuJa perangulata, Fanopcca simul- 



atrix, P. curta, Acella f^Pliysa Copei, var. Canadensis, Acroloxus 



radiaiulus, Patula angulifera, P. ohtusata, AncMstoma parvulum, Valvata 

 Jilosa, V. bieincta. ISTo new species are described from the Laramie of the 

 Souris River district. 



The following new forms are described from the "Fox Hills" and 

 "Fort Pierrft" groups of the Upper Cretaceous: Gervillia recta, var. 

 horealis, 3fodiola {Brachydontes) dichoioma, Cyprina ovata,ysiT. alta, Pro- 

 tocardia horealis, Panopwa subovalis, Scaphites subglohosus. 



The Belly River series, which the author thinks it would be imprac- 

 ticable on purely palaeoutological evidence to separate from the Lara- 

 mie and more especially from the " Judith River group." From the Pale 

 or upper portion of the series, two new species are described, Crenella (?) 

 parmila, Unio consuetus ; from the lower or yellowish and banded por- 

 tion of the series the following new species are described : Unio supra- 

 gibhosus, Ehytophorus {?) glaber, Planorbis paucivolvis, Hydrobia subcylin- 

 dracea. A number of fossils are mentioned as occurring in the "Lower 

 Dark Shales " of Dr. Dawson's report, but no more new species are 

 described. A number of fossils are also mentioned from uncertain 

 geological horizons.

The author reviews some previously expressed opinions on the age of 

 the Mesozoic rocks mentioned, as well as on the age of the Aucella- 

 bearing rocks of Europe, and criticises Dr. AVhite's remarks on his 

 identification of nine species with Jurassic fossils of the Territories.
