Remarks —The material at hand is probably representative of the 
race of bachmani occupying the “‘lower slopes of the Sierras between 
Shasta County and northern Tulare County,’’? which Nelson (1909, 
6c 
p. 249) refers to as ‘‘not typical’’ but in his estimation ‘‘nearest to 
bachmani.’’ 
The several distinctive characters displayed by our speci- 
mens seem to us to warrant fully the use of a separate name, 
especially in view of the apparent complete separation of the ranges 
of mariposae and bachmani. Tntergradation between these two forms 
probably takes place through cinerascens, around the southern end of 
the San Joaquin Valley. The latter race, however, is not at all inter- 
mediate in characters, but is divergent from both, notably in the matter 
of the enlarged auditory bullae.
