A3B4 CONTRIBUTIONS TO A REVISION OF THE 
questions sure to be soon brought up in the active advance of monographic work in 
American mammalogy. 
The synonymy of Pennant’s Fisher has already been discussed under Lutra hud- 
sonica, and I have there given reasons for my adoption of the plate-name canadensis of 
Schreber as having priority over the long-accepted name pennanti of Erxleben for 
this animal.

Type Locality —< New York and Pennsylvania,” Pennant. 
Geographic Distribution—Northern North America, east of the Cascade moun- 
tains, from the northern limit of trees to Colorado and North Carolina in the mountains. 
Intergrading on the Pacific slope into subspecies pacifica, and probably in the southern 
Rocky mountain region into a paler race. Probably represented in the Hudsonian 
faunal region by a subspecies.* 
Color—From an adult, male, winter specimen He near Lancaster, Pa., March 
11, 1896, and in the possession of Dr. M. W. Raub, of that city, who furnished 
the description : ‘‘ Head and one-half of the length of body, gray and black mixed, gray 
predominating ; throat darkest, with snout from tip to line of eyes dark brown. The 
hinder half of body gradually darkens into a deep chocolate color until it reaches the 
tail, which is almost black with a tip entirely black. Hind legs and tail, viewed at a 
distance of six feet, look very dark, almost pure black. The fore legs are black but not 
so deep. Tips of ears, darkest.” 
Two specimens from the Bangs: collection, one from Moosehead lake, Maine, the 
other from Idaho county, Idaho, seem to answer closely the above description. The 
light upper and forward portions of body are a grizzled grayish brown, the long hairs 
black tipped. The basal half of hairs of anterior back are hair brown. I can discover 
no color characters to separate the Idaho specimen from the one from Maine, nor do the 
skulls indicate any reliable differences. The Maine skin (of an animal two-thirds grown) 
* Typical canadensis must be restricted to the Alleghenian form.
