Columbia river; ears obsolete. No one since Richardson appears to have ob- 
served this animal. Schinz has made one 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. De, 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 incisors is mentioned by Richardson (Rerort 
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 imperfect, or too faulty for reference.
