154 Merriam Four New Bears from North America. 

 Ursus kenaiensis sp. nov. 



Type from Cape Elizabeth, at extreme west end of Kenai Peninsula, 

 Alaska. No. 128,672. Adult female. U. S. National Museum, Biological 

 Survey Collection. 1903. C. A. Lambert. 



Characters. Size large ; skull broad, flat and remarkably massive, with 

 exceedingly broad rostrum, not constricted at base, but spreading broadly 

 into zygomata; zygomata broadly spreading; jugal very broad anteriorly ; 

 frontals depressed, flattened, low posteriorly ; postorbital processes large, 

 blunt, projecting horizontally outward from top of skull ; palate exceedingly 

 broad; nasals large and broad; anterior nares rather small. Canines 

 small (as in the grizzlies) ; incisors and molars large. From Ursus richard- 

 soni, apparently its nearest relative, it may be distinguished at a glance by 

 larger size, broader palate, and by the form of the temporal ridges, which 

 do not turn abruptly inward behind the postorbital processes. From 

 kidderi and phseonyx it differs in greater massiveness ; much broader ros 

 trum, palate, and zygomata, and flatter 'frontals. Compared with kidderi 

 the skull as a whole is shorter and broader ; the incisors and canines 

 of approximately the same size. Compared with phaeonyx the skull is in 

 every way larger, broader, and far more massive ; the canines are approxi 

 mately the sam.e size ; the incisors larger. 



Ursus horribilis phseonyx subsp. nov. 



Type from Comet Creek (5 miles below head), a tributary of Forty Mile 

 Creek, near Eagle, Alaska. No. 133,231. Old female. U. S. National Mu 

 seum, Biological Survey Collection. July 12, 1903. W. H. Osgood. Orig 

 inal No. 2684. 



Characters. Similar in general to U. horribilis, but claws shorter, more 

 strongly curved, and dark blue-black [in horribilis long, flattish, and 

 mainly white]. Ears rather short and densely haired on both sides. Color 

 of skin dark brown. 



Color. Back and legs very dark brown, almost blackish brown ; tips of 

 hairs on back where not worn off grizzled ; underparts and muzzle pale 

 brown. 



Cranial and dental characters. Skull similar to that of horribilis, but zy 

 gomata more spreading, muzzle broader and shorter, especially broad ante 

 riorly; canines heavier; incisors decidedly larger. 



Measurements of longest (middle) claw of fore foot. Over curve, 93 mm.; 

 from top of base to tip, 75 ; from bottom of base to tip, 55. 



Ursus americanus eremicus subsp. nov.

 1902. E. W. Nelson and E. A. Goldman. Original No. 15,11 1.
