Columbia river; ears obsolete. No one since Richardson appears to have ob- 

 served this animal. Schinz has made ooe species of the description, and another 

 of the figure of this animal : his description of the latter seems concocted from 

 the text under Diplostoma? bulbivorum.

Pseudostoma castanops Baird, Stansbury's Exped. to Great Salt Lake, 313. 



Found near Bent's Fort. Dr. Baird does not mention whether the tail is naked 

 or hairy; the incisors are not described, probably because they were wanting, 

 and we have therefore no data to determine the position of this species. Judging 

 by the length of the exposed part of the anterior middle claw, it should belong to 

 the first division. 



A species with bisulcate superior iacisors is mentioned by Richardson (Report 

 British Ass. 5, 157,) under the name Geomys Drummondi, and by Wagner as 

 Ascomys Drummondi, but as no description has yet been published, the species 

 must of course be dropped from the books. 



The following descriptions are too ioiperfect, or too faulty for reference.
