330 C. Schuchert and B. S. Lull — Mammut Americanwm. 



The limb bones are relatively slender in proportion to their 

 length in comparison with those of the Warren mastodon or 

 the Otisville specimen mounted at Yale, both of which are 

 exceptionally powerful animals though differing markedly in 

 stature and general appearance. In size, the new skeleton 

 stands almost midway between them ; for instance, the ulna of 

 the forearm measures 28 inches in length in the Otisville 

 animal, 31 inches in that of Farmington, and 34 inches in the 

 Warren specimen, and the other measurements which I have 

 been able to compare run in much the same proportion. 



The Otisville specimen was not fully mature at the time 

 of its death, as certain of the vertebral epiphyses are still but 

 partially coalesced and the hinder ridges of the teeth show no 

 appreciable signs of wear. As mounted, this specimen, a 

 young male of abundant promise, stands 8 feet 2 inches at the 

 shoulder, with a length of 13 feet 2 inches from the tip of the 

 premaxillary bone to the curve of the tail. The assembled 

 bones of the Connecticut specimen, however, give an estimated 

 shoulder height at least 6 inches greater, though just how 

 the other dimensions would compare one cannot say ; but the 

 contrast of bone proportions seems to indicate that those of the 

 entire body would vary as well. The erection of the two 

 skeletons side by side for comparison would thus be of the 

 highest scientific importance. 



The tusks of the Otisville mastodon have not been found 

 and little idea of the relative length of this element can be 

 obtained. The size of the tusk socket would indicate a tusk 

 but a half -inch less in circumference than that recently found 

 at Farmington. The latter is 23 inches in greatest girth and 

 measures 8 feet 10 inches on the curve and 6 feet 3 inches 

 between perpendiculars. 



There is nothing to indicate that the Farmington mastodon 

 does not belong to the principal Pleistocene species, Mammut 

 (Mastodon) americanum, the known range of whose variations 

 is amply sufficient to account for all of the points of contrast 

 which have been mentioned.
