MAMMALS—URSIDAE-URSUS AMERICANUS. 
227 
Of two specimens from Louisiana, of nearly the same age with that first described, one agrees 
pretty well with it; the other exhibits a gentle concavity from between the orbital processes to 
the end of the nasals. 
In three very old specimens from Louisiana, the sagittal crest extends nearly as far as the 
middle of the frontal hone. In two of these there is rather more of a depression between the 
orbital processes than that described ; the third (a male) agrees very closely. The dorsal outline 
is altered in all as being less convex ; in one it is nearly straight from the end of the sagittal 
crest to the tip of the nose. 
A specimen (No. 1156) has a much shorter muzzle than the others, measuring only 0.29 of 
the total length, instead of 0.33, as given above. 
All agree in the general shape of the coronoid process as given above. 
Since writing the preceding article, I have examined a skull of the black bear from Saranac 
Lake, New York, which exhibits some very anomalous features, greatly differing from what has 
been described. The chief characteristic is the enormous breadth of the head, in this respect 
exceeding even the Ursus arctos of Europe. Thus, while the total length is 10.10 inches, the 
width is 1.60, a proportion of 100 to 11. A larger number of specimens from this locality, 
may perhaps furnish the clue to this remarkable variation, which, under other circumstances, 
would he readily allowed as indicating a distinct species.
