N. A. INVERTEBRATE PALEONTOLOGY. 755 



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

 and in some respects they remind one of the Gosau formation of Europe. 

 The author describes the new genus Coralliochama ; with C. orcutfi as its 

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



also described : Trochus {Oxystele) etiryostomus, Nerita f, Cerithiiwi, 



PiUingi, G. totiumsanctorum^ Solarium wallalense.

From the Laramie of the Willow Creek series the author describes 



Unio Alhcrtensis. From the Saint Mary's Eiver series and lower portion 



of the Laramie generally he describes the following uew species : Ano- 



mia pcrstrigosa.1 Gorbicida obliqua, Gorhula perangvlata, Panopaa aimul- 



atrix, P. curta, Acella f,Physa Gopei, var. Ganadensis, Acroloxus 



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

 Jilosa, V. bicincta. No new species are described from the Laramie of the 

 Souris Eiver district. 



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

 "Fort Pierrcfc" groups of the Upper Cretaceous: Gervillia recta, xar. 

 borealis, Modiola {Brachydontes) dichoioma, Gyprina. ovata, var. alta, Pro- 

 tocardia borealis, Panopwa subovalis, Scapliites subglobosus. 



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

 ticable on purely paheoutological evideuce to separate from the Lara- 

 mie and more especially from the "Judith Eiver group," From the Pale 

 or upper portion of the series, two new species aredescribed, Grenella (?) 

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

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

 gibbosus, Rhytophorus {f) glaber, Planorbis paiicivolvis, Mydrobia subcylin- 

 dracca. 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 oi)inions on the age of 



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



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



identification of nine sjjecies with Jurassic fossils of the Territories.
