of the fur. In this latter pelage it apparently would resemble the type 

 of C. peninsula. The specimen kindly loaned to me by Dr. Fisher, 

 from the collection of the Biological Survey, was taken on April 20th, 

 and is in the grizzled gray and black coat of winter, very much worn 

 and the skin partly bare in places. For comparison, therefore, 

 with my examples this skin is not of much assistance, but a glance 

 at the skulls is sufficient to perceive the distinctness of the two forms. 

 The skull of C. clepticus is short and broad, while that of C. penin- 

 sula, is comparatively long and narrow. The brain case of the new 

 form is swollen and rounded, much broader than that of the Cape 

 species, and the frontals at the postorbital processes are much 

 broader; the rostrum is more slender; the basioccipital, basi- 

 sphenoid, and palate posteriorly much wider; the pterygoid fossa 

 longer, and the carnassial and other molars smaller. The zygomatic 

 breadth also is much greater. Probably at the same season of the 

 year the coats of the two species would have a general resemblance 

 to each other, but the skulls would always indicate their distinct- 

 ness. This species seems to be a dweller of the higher elevations 

 of the San Pedro Martir range, as it was not met with in the foot- 

 hills or on the plains, being replaced in those districts by the pale 

 C. estor. It is a very handsome animal in full coat, and very red- 

 dish in midsummer.

This small fox appeared to be rare and restricted to the mountains; 

 as Mr. Heller remarks; it "evidently does not occur on the desert," 

 and none were seen in the country on the eastern side of the range.
