from callosities to two inches or more out on under side of tail. 

 Cheeks, throat, and breast white, blending to the more buffy-white 

 under parts of body and limbs. 



Skull. — Compared with an adult male skull of L. p. johnstoni, the 

 skull of the type is considerably narrower, with smaller orbits; and 

 long, narrow opening of anterior nares, two and one-half times as 

 long as wide. The palatine plate of maxilla is deeply concave, com- 

 pared to the flat surface of this bone in johnstoni. 



Measurements of type. — Head and body, 525 millimeters; tail 

 vertebrae, 610; hind foot, 140; ear from crown, 27 \ weight exactly 10 

 pounds. Skull: Greatest length, 110.5; condylobasal length, 84; 

 zygomatic breadth, 66 ; breadth of braincase, 54.5 ; upper molar- 

 premolar row, 25.4. 



Remarks. — In a series of five specimens from the type locality, 

 the color differences exhibited by this race are very constant and 

 conspicuous; and are even more accentuated in the immature skins 

 than in the adults. Unfortunately there is only one adult male skull, 

 and the cranial characters may prove of less value than the color 

 differences, though they seem to be beyond the range of reasonable 

 individual variation.
