beneath, pure white; no lateral line; hairs of 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

phase, as above described. One is No. 2463, from near San Francisco, which

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-
