from the Stikine were all dark. The skull pertaining to this specimen 

 has the small sized last upper molar that is supposed to distinguish 

 energumenos from nesolestes, but in the skull from Telegraph Creek 

 this tooth is as large as in most examples of the latter subspecies. 

 There is at hand a mink from near the mouth of the Taku Eiver and 

 one from "Wrangell, both of which are of the same dark color as our 

 Stikine Eiver specimen. Thus the specimens available suggest the 

 existence of a dark colored mainland form extending toward the coast 

 at least along the larger rivers, and reaching some of the islands lying 

 nearest the mainland, and a lighter colored subspecies existing upon 

 most of the islands of the Alexander Archipelago. There is not suffi- 

 cient material available, however, to verify this surmise. 



At any rate, the mink of the upper Stikine Valley is a relatively 

 small form, and not the large ingens of the nearby Yukon drainage. 

 At present it seems proper to use for this race the name Mustela vison 

 energumenos (Bangs), originally applied to the mink of southern 

 British Columbia. Our one specimen is very similar in appearance to 

 an example of energumenos from the vicinity of Seattle. 



Phoca richardi richardi (Gray). Harbor Seal 



Seals were observed as far up the Stikine River as Doch-da-on 

 Creek, at times in considerable numbers. On May 21, as we began 

 our trip up the river, they were seen in veritable herds over the first 

 thirty miles. At one place there were at least a hundred in sight at 

 once. Farther up stream they became less and less abundant. No 

 specimens were obtained, and t^e identification here accorded the ani- 

 mals seen is purely inferential.

Mouse 



Peromyscus maniculatus macrorhinus (Rhoads). Rhoads White- 

 footed Mouse 



One hundred and thirty-eight specimens of white-footed mice were 

 preserved, as follows: The Junction, 24 (all adults) ; Telegraph Creek, 

 29 (24 adults and 5 young) ; Glenora, 27 (23 adults and 4 young) ; 

 Doch-da-on Creek, 27 (15 adults and 12 young) ; Flood Glacier, 28 

 (10 adults and 18 young) ; Great Glacier, 2 adults; Sergief Island, 

 1 young. (Museum numbers 30569-30705, 31050.)
