70 BANGS — NEW AMERICAN MAMMALS ENE 
Remarks.— I have not seen S. a. klamathensis Merriam, but 
that form, described as having a very pale head and yellowish 
gray cheeks, does not appear to be much like the new form. SS. a. 
fascivus is more nearly like S. a. californicus than S. a. fuliginosus, 
but differs from the former in its darker brown upper parts and 
longer rostrum and nasals and larger audital bullae; from the 
latter it differs in smaller size and less smoky tints and paler 
tail. 
Scapanus californicus minusculus’ subsp. nov. 
Type, from Fyffe, El Dorado Co., California, 2 adult, no. 9189, coll. of 
E. A. and O. Bangs, collected June 10, 1897, by W. W. Price and E. M. 
Nutting. 
General characters Much smaller than true S. californicus, hind foot 
smaller; tail shorter, more slender, and less hairy”; color much paler — more 
gray, less brown; skull smaller, narrower behind; rostrum rather shorter and 
broader; teeth similar. 
Color.— Upper parts, uniform lustrous drab gray; under parts, lustrous 
cinereous. 
Measurements.— Type, Q adult: total length, 160; tail vertebrz, 31; hind 
foot, 21 mm. 
Skull, type: greatest length, 32.4; basal length, 28.2; zygomatic width, 
13.; mastoid width, 15.6; length of palate, 13.; greatest length of single half 
of mandible, 20.8 mm. 
Remarks.— In his monograph of the American moles Mr. True 
mentions specimens from the eastern side of the Sierras (Owen’s 
Lake) as being very small and pale. My example from Fyffe 
appears to be the same, and the form seems to require a name. 
Dr. Merriam has lately described a mole, Scapanus true, from the 
northeastern corner of California, a very different region from that 
from which the present form comes. It is said to have a narrow 
palate and narrow, slender rostrum. Apparently it is not much 
like S. californicus minusculus. One of the characters given is that 
the last upper premolar has a “strongly developed trenchant 
1 Minusculus — rather less, rather smaller. 
2 These characters of the tail may be individual, but in a large series of true S. californicus 
not one has a tail like the type of S. c. minusculus. Moreover, in the genus Sca/ofs the tail is 
an excellent character, serving, alone, always to distinguish the two subspecies aguaticus and 
australis.
