582 THE BEIDGER EPOCH. 



were somewhat shorter, as tlie femur is stouter for Its length than in the E. 

 indieus. It was intermediate in this respect between the latter species and 

 the species of Bhinocerus. 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 attach- 

 ments to the ligamentum nuchce 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 terrible laniary tusks. The 

 head must have been supported somewhat obliquely downward, present- 

 ing the horns somewhat forward as well as upward. The third or 

 posterior pair of horns towered above the middle ones, extending vertically 

 with a divergence, 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 Bovidce. The cores have remotely the form of those 

 of the Antilocapra americana, whence I suspect that the horns had an inner 

 process, or angle as in the prong-horn at present inhabiting the same 

 region. The nasal shovels may have supported a pair of flat divergent 

 dermal tuberosities, but this is uncei'tain ; they are not very rugose. 



The elevation of the animal at the rump was about six feet, distributed 

 as follows, allowance being made for the obliquity of the foot.

The anterior limbs were stouter than the posterior, judging from the 

 proportions in various species, and were no doubt longer if of the Probos- 

 cidian character. This would give us the • hypothetical elevation at the
