found in Spitzbergen, and that especially Lemmus hudsonius does 
not extend to this island as other authors have believed.

there are thousands now in the island. Letter from Mr. Muller, Ann. and

Lagomys princeps. Dr. Cooper remarks that this rare animal lives about 
the limits of perpetual snow on the Sierra Nevada, but is very rarely seen. 
He found it quite common in a very limited district, though difficult to ob- 
tain, from its extreme shyness. Though before found in the Bocky Moun- 
tains near South Pass, and Salt Lake, where it is called “ Coney,” this is the 
first record of its occurrence so far to the west and south. Proc. Calif Acad.
