“ P. baileyi is a type very different from any heretofore described. 
It is a large animal with a peculiar skull, which suggests affinities with 
P. paradozus on one hand, and with P. formosus on the other, though 
much nearer the latter than the former. P, columbianus is a peculiar 
local form of the olivaceus group. P. nevadensis, P. panamintinus and 
P. mexicanus are small forms with much swollen mastoids, belonging to 
the flavus-longimembris group. P. nelsonii, P. stephensii and P. canes- 
ceus belong to the penicillatus group of the subgenus Chetodipus.”
