 11, ranging from 10.50 to 12.50; tail to end of hairs 14.50, ranging from 14 

 to 15.50, hence much longer than the body. Above, clear plumbeous-gray; 

 beneath, pure white; no lateral line; hairs o^the tail gray at base, with a 

 broad subterminal band of black, and broadly tipped with white ; posterior 

 surface of ears brownish, particularly toward the base. 



This species is remarkable for the constancy of its coloration. Among 

 some thirty specimens before me, only two depart much from the normal

 from Fort Tejon, which is evidently in an abnormal condition of pelage. 

 This has the back brownish, and an unsymmetrical, irregularly-shaped spot 

 of brownish-yellow on the top of the head. Professor Baird also refers to a 

 specimen from San Francisco with a brownish back. There is a slight varia-
