Restoration. We may ascribe to the Loxolopliodon cornutus, form and 

 proportions of body similar to those of the elephant. The limbs, however, 

 were somewhat shorter, as the femur is stouter for its length v t .an in the 

 E. indicus. It was. intermediate in this respect between the latter species 

 and the species of Rhinocerus. The tail was quite small. The neck was 

 a little longer than in the elephants, but much less than in the rhinoce- 

 roses; the occipital crest gave attachments to the Mgamentum inuchce 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 some- 

 what obliquely downwards, presenting the horns somewhat forwards as 

 well as upwards. 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 Bovida 

 The cores have somewhat the form of those of the Antilocapra americana, 

 whence I suspect that the horns had an inner process, or were palmate 

 as in the prong-horn at present inhabiting the same region. The nasal 

 shovels may have supported a pair of flat divergent dermal horns, but 

 this is uncertain; they are not very rugose.
