128 Merriam — .1 Ncv Bear from Montague Island, Alaska. 



Characters. — Size larj^e; claws of adult Iohlt and of tlio grizzly type; 

 hairs over shoulders elongated to form a small hut distinet hnni]); ears 

 dark, with whitish tips; general cdlor lirownish, varying from i)ale to 

 dark, the hairs of the haek sumetimes yellowish tipped, those of the head 

 grizzled; enlor darkest (almost hlaekish) dii lielly, legs and feet. An old 

 she ))ear kilU'd.hy Sheldon ^lay IS, lilO."), is very pale grizzli'd gray on the 

 npperparts, and only moderately darker on the legs and feet. Tin- euh of 

 this hear, killed tin' same day, was in its 2d year (about Ki months old) 

 and is very pale — alnio.«t hntl'y gray — with dark feet and legs and a strongly 

 marked hump. 



Cranial < 'Jiaracfrrs. — Skull in general similar to that of keualrnsis l)ut 

 basisphenoid hroadiT and flatter, its length nearly equal to that of hasi- 

 occipital ; posterior roots of interpterygoid fossa more widely spreading; 

 condyle of jair more e.rscrted [in Icenaicrms sessile], reaching so far hack 

 that a line dropped from ]ieuk of coronoid to tip of angle touches or 

 traverses it [in kcnaiensis this line passes freely behind the condyle] ; 

 coronoid, in females of same age, smaller and lower — its area for muscular 

 attachment less; ramus of jaw strongly ))ellied posteriorlj', its inferior 

 border belriw tlie coronoid ^tromjhj conre.r doinnrard and curving eveidy, 

 with only a very slight break, to angular process. [In krnaiensis the 

 inferior border of ranuis is nearhj slraicjht (iiol appreciably bellied under 

 coronoid) and ends abruptly in a step or jog at some distance behind the 

 angle.] 



In general form and appearance skulls of females closely resemble thoi^e 

 of female kcuaieusis, diti'ering chiefly in the characters above mentioned 

 and in certain <lental peculiarities — notal)ly the smaller size and more 

 jiointed heel of the last upper molar, and the oblique truncation of the 

 1st upiier molar. 



Skulls of males dilier widt'ly from those of kenaicnsis. Only two full 

 grown males of slieldoni and one of kenaiensis are available for compari- 

 son.* The two adult c? skulls of slieldoiii, while full grown, are by no 

 means so old as the old male kenaiensis, compared with which they are 

 decidedly larger (averaging 2 inches longer), much higher, more massive, 

 broader across the .squamosals and also across the frontals (both inter- 

 orbitally and postorbitally). The ramus of the jaw i.s deciiledly broader, 

 and its inferior jjorder more bellied and convex posteriorly. The sagittal 

 crest does not reach the froutals [in the oM c? kenaiensis it readies to 

 middle of frontals] ; the frontals arch well upward, are traversed by a 

 broad median sulcus, and swollen above and behind the orbits; the nasals 



*1"lios(' of alicbhivi iiic llic typo, Xo. 1?>7,.')1S, collected l).v Slidduii in I'.Mi.'i; and a 

 slislitly older male of approxiinatcly the same size (No. i>70, Miis. \'ert. Zoo!., liiiversity 

 of Califoniia), collecleil and loaned by Miss .\nnie M. Alexander (killed by her lunitrr. 

 \. llasselborK. .Inly ,\\. I'.tdS. at Mel.eod llarlior, MoiUiiRne Island). The old male 

 kenaiensis (No. S'.IK), Mnsenm Vert. Zool., fniv. ( alif.) was collected by Andrew Berfi fur 

 Miss Annio M. Alexan<li'r, to whom I am indebted for the privilege of comi)arinK it 

 with skulls in the TSioloKical Survey coUeetion. It is very old and presents the maxi- 

 nunn ilevelopment of crests and ridges — the sagittal ci'est liein^i vi'ry louK and hiRh. 

 slinhtly convex, and reaching anteriorly to middle of frontals — the lenuioral ridnes 

 spreading thence at a right angle to the postorl)ital processes.
