There are several peculiar features about this squirrel, although its dusky tipped hairs on the 
belly seem to indicate it as one of several varieties of a single species. The figure indicates a 
dusky line on the flanks not mentioned in the description, as well as a greater amount of reddish 
in the belly than the text would indicate.

Length of head, 2 inches; head and body, 94; tail, 64. Tail rounded, slightly distichous, 
and rather pointed. Ears pointed. Thumb rudimentary. Pelage rather stiff. Each hair is 
white, brown, whitish yellow, and rusty. The general color is yellow, washed with reddish 
and black; beneath, pale yellow. Tail yellow and brown; the tips pale yellow. Tars black

According to John Edward Gray, this species is the same with Spermophilus beecheyi. I do 
not recognize this species in it, but think it may be some one of the Mexican or Lower California 
Spermophilus.
