80 Elliot — Three A^tpcirently Neiv Species of Mammals. 



Color. — Type: General hue of body, tail, legs and feet black ; the bases 

 of the long hairs a smoky white, showing rather consincuously on the sides ," 

 a pure white spot on the breast, and lower part of the abdomen, and large 

 spots on the fore part of eliest behind fore legs grayish white; head and 

 ears shining black ; tail l)lack, with few white hairs at tip; claws black. 



Other specimens are all black with very few grayish white hairs showing. 

 From this sable hue, which in certain sections seems to be the prevailing 

 one, the color varies in different mixtures of black and white to that in 

 which the white is the prominent color with jet black lines on dorsal sin-- 

 face and neck. The tail of this style is mostly white with black mixed in 

 in places and with the tip black. 



Measurements. — Skull: Total length, 263 ; Hensel,233; zygomatic width, 

 143; intertemporal width, 64 ; lateral length of nasals, 97; median length, 

 85 ; width of rostrum at canines, 55.5 ; palatal length, 126 ; width of palate 

 between sectorials at base, 64 ; length of upper tooth row, anterior edge of 

 canine to posterior edge of last molar, 114; length of canine, 36; alveolar 

 length of carnassials, 27; width of row of incisors at tips, 42 ; total length 

 of mandible, 206 ; depth beneath carnassial, 32 ; height of coronoid process 

 from lower edge of angle, 78 ; width of coronoid process at tip, 29. 



In a collection from the upper waters of the Sushitna River in the 

 region of Mount McKinley were the skins and skulls of several wolves, 

 remarkable for their large size and black color. While larger than any 

 that I had previously seen from Alaska, the size would not alone have 

 been deemed of consequence had it not been accompanied by the charac- 

 ters that are apparently not to be found in the timber wolves of the countries 

 to the south, and which make these animals worthy of being considered 

 as belonging to a distinct form. The skulls when compared with those of 

 C. occidentalis exliibit conspicuously the differences given in the description 

 above, and the peculiar coloration of the various individuals may not easily 

 be found among those of the allied species.

 SEA-GIRT OR ISLAND OTTER. 



Ti/pe from Gawi, west coast of Moresby Id., Queen Charlotte Islands, 

 British Columbia, Canada. No. 491, Field Columbian Mus., Chicago. 



General characters. — Skull: Size large; intertemporal region long and 

 narrow, greatly constricted for its entire length ; in young animals this con- 

 striction is not so apparent. Rostrum short and very broad ; postorbital 

 processes greatly elongated ; braincase without crests, rounded, and widest 

 posteriorly; bullae small and flat, barely rising above the level of the 

 basioccipital ; pterygoid fossa broad for its entire length, the sides nearly 

 straight but widening gradually to tips of pterygoid processes where the
