band from two to several inches in width, but strongly varied with blackish 

 tipped hairs. Sides of the body and outer sides of limbs pale buffy gray ; 

 ventral surface and inner side of the limbs white, the basal portion more 

 or less buffy, particularly at the base on the abdomen. Tail strongly 

 bicolor, the dark dorsal band being continued down the upper surface of 

 the tail to the tip, the sides and lower surface of the tail being buffy white. 

 Eyelids and an indistinct patch on the upper lip at the base of the whiskers 

 blackish. Forehead and nose brownish gray, lighter and more whitish 

 between the orbits. Ears buffy gray, mixed strongly with blackish at the 

 base and tip, leaving an enclosed large grayish area over the middle por- 

 tion. The dark color at the base and tip is strongest at the base of the 

 ear and lighter and more mixed with brown at the apical border. 



This specimen is evidently in winter coat, judging by the fullness and 

 length of the pelage, the hairs of the upper surface of the body averaging 

 from 25 to 30 mm. in length, while the white hairs of the lower part of 

 the abdomen (inguinal region) attain a length of 70 to 80 mm. 



Gray phase. — Am. Mus., No. 17433, 9, Smith's Ranch, near mouth of 

 Rio Coy, on the coast, about sixty miles south of Santa Cruz, Patagonia; 

 Barnum Brown. Total length, 2285; head and body, 1470; tail without 

 hairs, 815 ; hairs at end of tail, 55 ; ear from top of head in dried skin, 80. 



General color above gray, slightly inclined to ferruginous on the top 

 of the head and less so on the shoulders. A dark rufescent brown dorsal 

 stripe about 2 to 3 inches in width extends from the shoulders to the base 

 of the tail, slightly varied with black-tipped hairs. The gray of the sides 

 becomes paler toward the lateral line and passes insensibly into pale buffy 

 white on the ventral surface and inner surface of the limbs. Outer surface 

 of the limbs like the sides of the body. Tail sharply bicolor, the upper 

 third being a continuation of the dorsal band, but darker and more mixed 

 with ferruginous. Sides and front of the face gray, slightly varied with 

 black-tipped hairs ; a blackish patch at the base of the whiskers ; upper 

 eyelid edged with blackish. Ears black at the base and tip, enclosing a 

 large patch of gray. 



This specimen is evidently in summer coat, the pelage being short, 

 scarcely exceeding 15 mm. in length on the upper surface of the body. 



A young example, in spotted coat (Am. Mus., No. 17435), also col- 

 lected by Mr. Barnum Brown, differs considerably in color from the adult, 

 as follows : General color above dull pale fulvous, darker over the
