Dentition very similar to that of Sttnoiii/cleris. Upjier incisors 

 small, terete, distinctly spaced, crown scarcely ditt'erentiated from 

 shaft; lower incisors when perfectly unworn slij^htly Idlobed (the 

 small median notch in the cutting-edge disappears very soon by 

 wear). Upper canines long and tliin, with a well-marked longi- 

 tudinal groove along anterior surface, generallj' a distinct trace of 

 a cingulum at posterior base of teeth, scarcely any at all at inner 

 base; lower canines slanted conspicuously outvTard. p' subequal 

 to an u|)per incisor ; p'-m' and p.,-tnj as narrow as, and scarcely 

 differing in any noteworthy character from, those oi Stenonycteris ; 

 m' and m, individually somewhat variable in size and shape, 

 the former nearly always distinctly larger than p', m^ (if present) 

 as a rule smaller than p^.

External t/mwc/crs.— Muzzle thinner (and, chiefly for that reason, 

 looking longer) than in typical ]\'urisi'tl(is ; odontoid papills; on lips 

 absent (in liouseftus a single short and thin row fringing \ipper and 

 lower li[)3 at angle of UHiutb). Ears as in liousettvs ; antitragal 

 lobe small, rounded-triangular. Length of toil as in Uovsettwi 

 (tail-vertebra) seven, the terminal one very small). C'alcar a little 

 shorter than in tyi)ical RouBctUm, between ^ and \ of foot with 

 claws. A large kidney-shaped gland on either side ol anal opening, 

 present in both sexes (absent in lionseltus). Lateral membranes 

 arising widely separated from sides of back and inserted posteriorly 

 on extremity of first metatarsal, or between first and second, or on
