Remarks. — P. I. fuscipes requires rather close comparison with P. I. 

 hirtus to the north and P. I. hernandesii to the south, but typical 

 specimens differ in combination of characters as pointed out. It is 

 readily distinguished from P. I. varius by much larger size and from 

 P. I. me xicanns by darker color. Intergradation with all of these may 

 safely be assumed. In typical fuscipes, however, the facial mask 

 usually extends as a broad, uniformly black area across the face as in 

 P. I. mexicanns and western subspecies in general, instead of being- 

 more or less distinctly interrupted by whitish longitudinal lines, one on 

 each side near inner angle of eye, tending to isolate a narrow, elongated 

 l)lack median patch as in hirtus, varius and other eastern continental 

 forms. In fuscipes the brain case, on the other hand, is somewhat 

 depressednear the front o-parietal suture and the postorbital processes 

 of the frontals are very short or obsolescent, characters shared with 

 hirtus, varius and the eastern subspecies in contrast with mexicanus and 

 the more western and southern continental forms in which the depres- 

 sion of the brain case is less evident, and the postorl)ital processes of 

 the IVontals are well developed.
