436 CONTRIBUTIONS TO A REVISION OF THE 



feet. Type, No. 1074, old ad. ?, in the collection of S. N. Khoads; collected in the fall 

 or winter of 1892-'93, by Allan Kupert.* 



Geographic Distribution. — Pacific slope of America, from Alaska to California. 



Color. — Above, from between eyes to middle back, grizzled, grayish ochraceous 

 heavily lined with black, becoming hazel black on hind back and dark black on rump, 

 thighs and tail. Whole head, behind eyes clove brown basally, strongly grizzled with 

 dirty white. Snout to eyes blackish seal brown. Chin, throat, breast and belly between 

 dark chestnut and hazel, obscured with black. Legs and feet black, the fore legs show- 

 ing the vandyke brown bases of hairs. Basal half of hairs of anterior back are Prout's 

 brown as contrasted with the hair brown of canadensis. 



Anatomical Characters. — Size, large, skull very large, with relatively long nasals. 

 Posterior upper molar large, with spreading inner lobe much wider longitudinally than 

 outer section of same tooth ; the crown suddenly constricted at the middle. 



Measurements. — Of type from relaxed skin : Total length, 1090 mm.; tail, 350 

 mm. without brush ; hind foot not determinable, as the bones are missing. Measure- 

 ments of a specimen two-thirds grown, No. 295, coll. S. N. Khoads, from near Tacoma, 

 Wash.: Total length (relaxed skin), 970 mm.; tail, 400 mm.; hind foot, 112 mm.; 

 ear from crown, 21 mm. Skull of type : Total length from hinder end of sagittal crest 

 to front end of premaxilke, 125 mm.; zygomatic expansion, 73 mm.; mastoid expansion, 

 54 mm.; interorbital constriction, 28.5 mm.; postorbital constriction, 20 mm.; mesial 

 length of nasals, 27 mm. 



Remarks. — The dimensions of the type skull, when we consider it was from a 

 female, show that the fishers of the Cascade mountains attain a much greater size than 

 those of the Appalachian chain. Young adult skulls of the same age from western 

 Washington and Maine show the same distinctions. The younger specimen from Tacoma, 

 while approaching nearer to Idaho and Maine specimens in grayer color, is very much 

 darker than they, the difference in shade between the anterior and posterior dorsal areas 

 of the former being slight, while in the latter it is striking. The tawny suffusion so 

 deeply marked in the type of pacifica and which separates it at a glance from canadensis 

 is also noticeable in the Tacoma specimen. 



Specimens Examined. — Washington, Lake Kichelos, 1 skin with skull, 2 skulls; 

 near Tacoma, 1 skin, 1 skull ; British Columbia, Sumas, 1 skull. 



* Mr. Ruperfc, whose business is hunting and trapping, first sent me the fresh skull of a very old 9 fisher, which 

 was entered in my catalogue as No. G21. I wrote him immediately that I would like to have the pelt belonging thereto, 

 and in a later shipment the skin, which forms the type of pacifica, was sent on without label. As it is also from a female 

 and a very old animal, I consider the skip and skull as belonging to the same individual.
