Teeth. All the teeth with the exception of the last lamina of 

 the third molar are visible when viewed from the outer surface in 

 profile. In all the Mns I remember to have examined, the third 

 molar, and frequently a large portion of the second, is hidden by 

 the front edge of the ascending ramus. 



The molar lidges appear to be rather simple, the outer tuber- 

 cule is ill developed while the inner one of M^ is bent backwards 

 and set somewhat behind the lamina, its longer axis is anterio- 

 posterior. The teeth of the specimens examined are abraided so 

 that the condition cannot be wholly ascertained. 



There is some difierence in the size of the adult specimens 

 measured, but the general color, form, and cranial characters 

 do not present features of specific import. 



In reference to the following scale of dimensions, attention is 

 drawn to the fact that the measurement " Heel to front of fourth 

 foot pad " is not comparable with " Heel to front of last foot 

 pad " (the inner metatarsal) as rendered in all species excepting 

 this and the one next described. It may be further explained 

 that the Avord " fourth" refers to the position rather than to the 

 number, for examples may be examined which have three pads 

 only, the first interdigital being absent : a reference to the dia- 

 gram on page 118 will render the description easier to follow. 



Also, in cases, as in the present species, where the pad 

 measured is very small, the size of that of one individual alone 

 lias been given, for no benefit could accrue from elaborating such 

 an approximate dimension as this one must necessarily be.
