This form, which is very uniform in its characters throughout a very extensive territory, and therefore 

 entitled to recognition, entirely replaces both .V. /ormi'ciVoniit and .If./. ^air(/i' in the region indicated above. 

 The measurements and habitat of M./, bairdi given on page 291 include the present form and require correction 

 accordingly.

A'liic. — It is not improbable that the Califomian binis of this species, at Icist those from the more humid 

 and wooded northern coast districts, will have to be separated as a local race, characterized b3' very dark colors, 

 with heavier markings. At least the two Californian examples in the X.itional Museum colloctinn (one from 

 Nicasio, the other from Calaveras County) are altnjjethcr darker than any from elsewhere. Should additional 

 material show the observed diCTcrcncos to bo constant, I would propose for this dark Dorlhwestern race the name 

 P. nuttalli callfornicu:
