are four or five more, making in all in each side of the jaw about 

 twenty teeth. All these teeth are placed a little apart, and have 

 depressions behind them in the alveolar border ; the tusks also 

 are accompanied by similar depressions. 



Not far from the spot where this fine skull was obtained, two 

 mandibular rami (a right and a left) occurred two or three feet 

 apart. They are of the same size, and most probably belonged 

 to the skull in question. This would seem to be likely, not only 

 on account of their close proximity, but also on account of their 

 size, which agrees well with that of the cranium. The left 

 ramus is imperfect, the posterior portion having been fractured 

 and lost.. A piece nine inches long, however, of the anterior 

 portion remains in a very good state, with the stumps of the 

 teeth attached. The right ramus is almost perfect ; the alveolar 

 border is quite so, and exhibits the teeth in a beautiful state of 

 preservation ; a great portion of the dentary bone is present, 

 and is covered with the usual reticulated sculpture ; the anterior 

 extremity is quite perfect, as well as the articular bone — at the 

 posterior end with the glenoid surface, which is transversely 

 elongated, deep, and considerably elevated. 



This large and perfect ramus is nearly fourteen inches and a 

 half in length, and at the widest part, which is about four inches 

 from the posterior extremity, is two inches and three-quarters 

 broad. From this point it tapers gradually to the anterior end, 

 where it is little more than an inch wide. The inferior margin 

 is slightly convex ; and the alveolar border is somewhat con- 

 cave, with a slight eminence in front giving support to the first 

 large tusk-like tooth. 



There are upwards of twenty teeth, seventeen or eighteen of 

 which are well preserved : a dozen are entire. They vary much 

 in size,, and in some places are arranged almost in contact ; in 

 other places they are considerably apart. Three are much larger 

 than the rest, and seem to correspond to the vomerine and palatal 

 tusks of the skull. These large teeth are one inch and a half 

 long, and are upwards of half an inch wide at the base. The 

 first of these is placed an inch from the anterior extremity, upon 

 the eminence of the alveolar border already noticed; a single
