SUS-STUDIES. 177 



ditto spot is between the uppermost and second band, 

 meanwhile there are several large and small spots on the 

 buttocks; in a later state these spots meet to form true 

 bands ; in fullgrown specimens the general hue is a yello- 

 wish brown, a much lighter color than in vittatus. There 

 is like in vittatus a light colored band over the nose and 

 on the cheeks, in Milleri however the color is a yellowisb 

 brown. For the rest all the bristles on the body are shorter 

 than in vittatus and appearantly wider apart planted, 

 meanwhile each bristle has a yellowish brown colored sub- 

 apical ring. Ears and tail like in vittatus, as far we can 

 judge after dried skins. No warts, protuberances or tufts 

 of bristles like on the head of harbatus- and verrucosus- 

 specimens. 



The head makes a duller impression than that of vittatus^ 

 originating from being broader between the ears and shorter 

 than in that species; consequently the skull is shorter 

 than in vittatios. There is moreover a very constant character 

 in the distance between the frontal and premaxilla bones 

 along the sides of the nasalia being much greater constantly 

 than in vittatus. The nasalia are much shorter than in 

 vittatus, nay in the skull generally is a striking tendency 

 towards shortness, so that f. i. in a very adult skull the 

 anterior upper premolar is as it were pushed away from 

 its alveole and often is replaced by the second upper pre- 

 molar very closely set to the canine. For the rest I fail 

 to see differences in the dentition between this and the 

 foregoing species, nor in the extension of the bony palate 

 posteriorly. The premaxilla-bones are less extended foreward 

 than in vittatus. 



Skeleton with 14 dorsales and 14 ribbs, 5 lumbares 

 and more than 20 sacrales and caudales taken together 

 (the end of the tail is wanting) ; the form of the ribbs 

 much more remembers these parts in verrucosus than in 

 harbatus, the anterior ones are thick but narrow, mean- 

 while the posterior ones are broader, however less flat than 

 and not so broad as they are in harbatus.
