OCCURRENCE OF LOXOMMA ALLMANNI. 205 



backwards, and finally forwards and outwards, reaching the 

 straight external margin of the malar at the posterior point of 

 the maxilla. This enlarged posterior portion is upwards of an 

 inch and a half wide. 



The orbits are both imperfect in front, the anterior boundaries 

 having been broken away ; but the form, notwithstanding, is 

 determinable throughout. They are very large, measuring up- 

 wards of four inches long and one inch and a half wide at the 

 projection of the interorbital bone. Behind this point, which 

 divides it into two parts, an interior and posterior, the orbit 

 extends obliquely outwards and forwards ; and in front of it the 

 anterior division, which is the larger, turns a little inwards and 

 forwards. 



The maxillae extend backwards to within three inches of the 

 external cornua ; as much as four and a quarter inches of the 

 posterior portion is present : they are narrow and straight, and 

 border the straight outer margin of the malar, forming the lateral 

 boundaries of the cranium. In the right maxilla there are five 

 teeth — four towards the anterior fractured extremity, and the 

 fifth, of which the stump only remains, is seven-eighths of an 

 inch from the hinder extremity. Three of the anterior ones are 

 perfect : the first is placed a quarter of an inch from the broken 

 end of the jaw, and is about half an inch from the next tooth ; 

 the second, third, and fourth are a quarter of an inch apart (the 

 crown of the latter is gone) ; the fifth is placed an inch and three- 

 quarters further back, the intermediate teeth having probably 

 been removed. The remains of three or four teeth are observed 

 in the left maxilla, placed about the same distance apart as those 

 of the right maxilla. 



These teeth are of equal size ; the perfect ones measure three - 

 tenths of an inch in length ; they are grooved from the base 

 halfway up the crown ; the upper portion is compressed in the 

 direction of the long axis of the jaw, and the sides are produced 

 into wide, sharp-cutting margins; the extremities are abruptly 

 pointed. 



A large palatal tooth or tusk is seen a little within the frac- 

 tured extremity of the right maxilla, sinking into the matrix ;
