The skull from which the above dimensions are taken has 
been removed from the skin of an adult male animal, and, 
compared with a skull of the IJ. Quica, also belonging to an 
adult male, differs in being considerably smaller, and in 
having the nasal bones more expanded behind. The palate 
in D. Quica has two longish palato-maxillarv openings, and 
four other openings behind these, plnced nearly in the same 
transverse line: the middle two are rather longer than broad, 
the breadth being about one line. In D. nudicaudata there 
nre but two of the four openings just alluded to, the middle 
pair being absent; and the pnlnto-maxillary openings are 
considerably smnller. The foremost upper premolar, moreover, 
in this animal, is plnced neurcr to the second premolnr than 
in D. Quica, the muzzle being rather less elongated.
