4. DKOMXCIA. 147 



back, inner sides white, but the hairs partly grey basally. Tail about 

 as long as the head and body, slender, not incrassated, its basal 

 half-inch furry like the back, the remainder uniformly short-haired 

 as usual. 



Shull on the whole very similar to that of D. nana, with which 

 it agrees closely in its general proportions, and in the degree of in- 

 flation of the posterior root of its zygoma. Bullae very large, swollen, 

 transparent. 



Teeth (PI. XVI. fig. 8). Upper i.' and canine about equal. 

 P.' and p.^ minute, cylindrical, single-rooted as in D. nana, but 

 their positions more as in D. lepida, as they stand about equidistant 

 from each other, from the canine, and from p.* P.^ large, pointed, 

 markedly higher than the molars, not bifid at its extremity, and 

 without a posterior cusp. Molars three, as in B. nana, narrower 

 and more oblong than usual. Lower intermediate unicuspidate 

 teeth generally four in number, apparently corresponding to i.^, p.', 

 p.', and p.* ; but a fifth, probably i.', present on the right side of 

 specimen d. The lower p.* is therefore quite different from that of 

 the other species, being minute and unicuspidate like p.^ Molars as 

 in the upper jaw.
