INVERTEBRATA. 297 



undoubted marine genera have been identified from the Tertiary strata 

 of Bijou Basin, 40 miles E. of Denver, Colorado, indicating the extension 

 of open-sea marine deposits much further into the interior of the con- 

 tinent during the Tertiary period than had been suspected. The new 

 species described are : — From the Carboniferous rocks, Amplexus za- 

 phrentiformis^ Eupcwhycriniis pJatyhasis^ Archceocidaris cratis, Naticopsis 

 remex ; from the Jurassic rocks, Unio Steivardi, Neritina ? PowelU ; 

 from Cretaceous beds, 9 Lamellibranchs and 12 Gasteropods ; from 

 Tertiary beds, 8 Lamellibranchs and 13 Gasteropods (for names of these 

 see Index of Species). H. A. N.

 The new species described are : — StricHandinia castellana, from the 

 Niagara Limestone ; Chcetetes Muscatinensis, Monticidipora monticula, 

 Strohilocystites Calvini, Megistocrinns Farnsworthi, Parcuydas Sabini, 

 Conidaria molarif, Belleroplwn Bowmani^ Cyrtoceras dictyiim, and Ten- 

 taculites Hoyti, from the Devonian ; and LophopJiyUum expansum^ 

 Allorisma Marionensis^ and Euo7nphcdus Sprinyvalensis, from the Sub- 

 Carboniferous. The genus Strohilocystites is founded for the reception 

 of a new Cystidean, which is remarkable as being the first representative 

 of this order as yet identified with certainty from Devonian rocks.

 Gives a preliminary consideration of the deposits in which the fossils 

 occur, and the general nature of their organic remains. Describes 21 

 species of Cephalopoda, including 8 new Ammonites, and some undeter- 

 mined species of Ammonites, Belemnites, and Hamites. 7 Gasteropods 

 are determined, Amauropsis tennistriata and Pleurotomaria Skidega- 

 tensis being new. 22 Lamellibranchs are recognized, many in too im- 

 perfect a state for specific determination ; but 7 are new. Notices two 

 undeterminable species of Terehratida, and a coral, likewise undeter- 

 minable. Considers the pala^ontological relations of the Cretaceous 

 rocks of Vancouver, and arrives at the conclusion that the coal-bearing 

 rocks of Queen Charlotte Islands, which have yielded the fossils 

 described, can hardly be older than the Upper Jurassic or younger than 

 the Middle Cretaceous. For the names of the new Cephalopods and 

 Lamellibranchs, see Index of Species. H. A. N.
