width is greatest ; upper inolais very \nrge, the cusps on exterior side very 

 hiirli and acute; last molar square-shaped, slightly widest on interior edge.

 row, anterior edge of canine to posterior edge of last molar, 40 ; length of 

 nasals, 17.5 ; total length of mandible, angle to tips of incisors, 76; length

 alveolar border, 4(5 ; length of canine, 18 ; length of lower carnassial, 15. 



In a small collection of skulls presented to the Museum by Dr. C. F. New- 

 combe from the Queen Charlotte Islands were three of otters. Comparing 

 these with skulls of L. c. paclficn, rather striking differences are at once per- 

 ceived, such as the unusually lengthened constriction of the intertemporal 

 region, the smallness and flatness of the bullae ; the heavy wide rostrum 

 and muzzle, and the large longcusped molars. The postorbital processes 

 in the type project outward and backward like horns and the various dis- 

 tinctive characters and comparative differences exhibited between the skull 

 of this island animal and that of the mainland species indicate that they 

 may not properly be considered as one and the same. It is evidently 

 a large and powerful animal, possibly exceeding in size its near relative. 

 The other skulls fi-om Queen Charlotte Island were those of Ursust rarlottae 

 Osgood and Mustela nesophiia Osgood.

MOUNT McKINr,EY WOLVERINE. 



Type from upper waters of Sushitna River, region of Mount McKinley, 

 Alaska. No. 9883, Field Columbian Mus., Chicago. 



General characters. — Type: General color very dark ; no bufFhue on body, 

 or gray on head anywhere visible. Skull compared with that of specimens 

 from New Brunswick, Canada, is narrower, especially at intertemporal re- 

 gion, also postorbital constriction and posterior region of braincase|; and the 

 zygomatic width is less ; but the audital bullae are nearly twice as large, 

 and swollen greatly on their inner margin, whereas those of the Canadian 

 animal are much flattened and small in size. 



Color. — Head, throat, sides of neck and body, and base of tail chestnut ; 

 hind part of neck, back, underparts, legs, and feet black ; chest spotted 

 or blotched with white or orange, and orange spot on anal region ; nose 

 darker chestnut than head ; tail, except at base, black. 

 . Measurements. — Skull: Total length, 157 ; Hensel, 133; zj'gomatic width, 

 104; intertemporal width, 47 ; postorbital constriction, 32; palatal length, 

 75 ; greatest width of braincase, 67.5 ; mastoid width, 89; post-palatal length, 

 57 ; length of nasals, 21 ; length of upper premolar and molar series, 41 ;
