48 The Amblypoda., [ January, 
Mr. Osborn, of Princeton, has published a description of the 
lower jaw and teeth of a species of Loxolophodon, which he 
identifies with the Z. cornutus, which was derived from the local- 
ity and horizon of the species above mentioned (Fig. 8). They 
show that the descending flange of Uintatherium and Bathyopsis 
is only represented by a convex ridge on each side of the sym- 
physis. They point out the characters of the dentition, which 
are remarkable. The molars much resemble those of Bathyop- 
sis. The canines and incisors are alike in form, and in a contin- 
uous series. The crowns are compressed so as to be extended 
anteroposteriorly, and are deeply emarginate, so as to be bilobed, 
° the lobes with subacute edges. This 
form of incisors is unique, resembling 
® a only remotely the large median incisors 
9 of certain Insectivora (Fig. 30). Resem- 
blance to mammals of the same type 
may be traced in the molar teeth. 
We may ascribe to the Loxolophodon 
We ws chee form and proportions of body 
teeth of left side of lower jaw Similar to those of the elephant (see Plate 
eae Sue fourth 1), The limbs, however, were some- 
what shorter, as the femur (Fig. 31) is 
stouter for its length than in the Æ. indicus. It was intermediate 
in this respect between the latter species and the species of Rhi- 
noceros. The tibia is relatively still shorter. The tail was quite 
small. The neck was a little longer than in the elephants, but 
much less than in the rhinoceroses ; the occipital crest gave at- 
tachments to the “gamentum nuche and muscles of the neck, 
which must needs have been powerful to support the long muzzle 
with its osseous prominences, and to handle with effect the terri- 
ble laniary tusks. The head must have been supported some- 
what obliquely downward, presenting the horns somewhat for- 
ward as well as upward. The third or posterior pair of horns 
towered above the middle ones, extending vertically with a diver- 
gence when the head was at rest. The posterior and middle pair 
of horns were no doubt covered by integument in some shape; 
but whether dermal or corneous is uncertain. Their penetrating 
foramina are smaller than in the Bovide. The cores have re- 
motely the form of those of the Axtilocapra americana, whence I 
suspect that the horns had an inner process or angle as in the
