The only specimen in the collection equally old with the oldest of those from the Platte is 
No. 1804, from Essex county, New York. This agrees very closely with No. 1311 from the 
Platte, and is only a little narrower, with rather more slender muzzle. The temporal crest is 
very strongly marked. 
A skull from Fort Kipley, (1194,) Minnesota, equally adult with any, has a narrower fore¬ 
head ; it is of the same proportional width between the zygomata, if the distance from incisors 
to condyles be taken as the standard, hut narrower in proportion to the total length. It may as 
well he stated here that there is a considerable disproportion between the excess of the total 
length of the skull over the distance to the condyles, even in specimens otherwise similar. 
One specimen of gray wolf from the Platte (885) is much narrower, and has a longer muzzle 
than any other in the collection. Its width is but 0.48 of the total length, or 0.52 of the
