m^). Their limits posteriorly are determined by a very slender 

 bridge of bone, almost in the form of a St. Andrew's cross; likewise 

 the suture between the palatine bones lies in a string of bone, almost 

 as fine as a hair. 



In the yoimg (A) the palatine bones are not entirely perforated, 

 but the foramina form a network. 



The teeth. The dentition in all is normal: 



ih c'^.ph'^i (28). 



In the Upper jaw the edges of i ^ and i ^ have about the same 

 width, but «3 has a distinct groove. There are no traces of the ca- 

 nines, although a rudimentary socket is visible. 



The premolar (jp'^) is long, and has a sharp cutting edge; in the 

 oldest individual (F) its length is about equal to that of the base of 

 m ' ; in the other younger specimens it is still larger. 



In the young (A), in which the length of the skull is about 

 58 mm , the upper i ^ has not as yet risen above the level of the 

 socket, and i ^ is larger in comparison to i\ than in the mature spe- 

 cimens, The premolar (j) ^) is large, but with a sharp edge; the milk 

 premolar resembles a molar. Above the space between their roots is 

 hidden the germ of jp^. 



Of the molars m ^ is half grown. 



In the lower jaw the premolar Q? ^) is smaller and narrower than 

 that in the upper , and considerably resembles a normal ^ ^ in the 

 mature specimens. The germ of ^ ^ lies hidden under the converging 

 roots of p ^ and the milk premolar,

Diagn.: Colour reddish yellowish grey: the back 

 with interspersed black hairs. Snout and toes quite 

 black, likewise neck and under side of the tail. 



On the skull, the frontalia are broad and inflated 

 in front, and the intermaxillaria have their greatest 

 breadth above the middle. The length of the body (the 

 head included) is about 650 to 700 mm (and above); the 

 tail somewhat longer.
