We now desire to invite attention to the supposed species named Hes- 
peromys “gambeli”, in proposing which Professor Baird remarks pertinently:— 
“This species, in size and general appearance, represents very closely the 
Hesperomys leucopus of the Eastern States, to such degree, in fact, that I have 
not found any easily-expressed characters to separate them.” We ourselves 
fail to appreciate any differences whatever that are applicable to even a fair 
proportion of the specimens examined, though some are paler than ordinary 
leucopus ; we cannot even make Professor Baird’s qualified expressions hold 
good. This, however, being merely our opinion, good for what it may be 
worth, we are called upon to prove the point. With all the original speci- 
mens and many additional ones before us, we first present a table, and will 
then discuss the same.
