Adult male (No. |^ collection of Dr. C. Hart Merriam, Elk Kiver, 
Minn., January 30, 188G, Vernon Bailey collector) : dorsal surface very 
dark seal-brown with a slight greenish gloss, each hair with a narrow 
subterminal band of smoke-gray separating the seal-brown tip from the 
slate-gray under fur, and producing a slight grizzled appearance when the 
animal is viewed in certain lights; ventral surface very pale smoke-gray, 
nearly white, and faintly tinged with cream color; the color of the belly 
extending a short distance on the sides where it shades quickly into the 
color of the back; inner surfaces of all four legs colored like the belly; 
dorsum of manus and pes sepia, paler on the inner half; tail clear seal- 
brown dorsally and at tip, pale smoke-gray ventrally, this gray area 
broad proximally but soon narrowing to a mere line, persisting, however, 
to the extreme tip. 
The other adult male from the same locality (No. §506 collec- 
tion of Dr. C. Hart Merriam, February 20, 188G) is similar to 
the one just described, but has the ventral surface much more 
strongly tinged with cream color.
