CANADA OTTER. 
from Canada and the Rocky Mountains, we have but with one or two ex 
ceptions found the colour on the under surface lighter than on the back. 
A specimen from Carolina, an old male, teeth much worn. 
Upper lip from the nostrils, chin and throat to near the chest, grayish 
white ; the fur on the back, although not quite so long as that of speci- 
mens from Canada, is quite dense and silky, and very nearly equal in fine- 
ness. It is whitish at the roots, with a bluish tinge towards the extremities. 
The longer hairs which conceal the fur and present the external colouring 
are very nearly of the same tint as in those procured in Canada, so that 
the specimens from these widely separated localities can scarcely be re- 
garded even as varieties. 
A specimen from Colorado, Texas. 
(The form is precisely similar to the Otters of Canada and those existing 
in various intermediate States. The palms are naked, with a little less 
hair between the toes on the upper and under surfaces.) The colour is 
throughout two shades lighter than that of specimens from Canada, but 
the markings are similarly distributed. Fur on the back from the roots 
soiled white, inclining to brown at the tips. The long and rigid hairs on 
the upper surface lightish brown at the roots, then dark brown, tipped with 
lightish brown.
