 than the third, which, again, is slightly larger than the second

Schizostoma minutum, Gervais, Exped. du Comte de Castelnau, Zoo- 

 logie, p. 50, pi. vii. fig. 1, pi. x. figs. 6, 5 a (1855). 



Slightly smaller than Sch. megalotis, the head, ears, and nose-leaf 

 very similar to those of that species ; but easily distinguished by the 

 greater length of the foot, the shorter calcaneum, and the quality 

 and distribution of the fur. 



Second phalanx of the middle finger exactly equal to the first in 

 length ; metacarpal bone of the thumb equal to the remaining parts; 

 metacarpal bones of the third, fourth, and fifth fingers equal, as in 

 Sch. megalotis. 



The wing-membrane scarcely extends to the extremity of the 

 tibia ; the calcaneum is shorter than the foot, and the latter is com- 

 paratively larger than in the preceding species. 



Pur longer than in Sch. megalotis ; the muscular part of the fore- 

 arm, which in that species is almost quite naked, is here well 

 clothed on both sides. Above, brown, the base of the hairs ashy 

 white ; beneath, ashy. 



Teeth as in Sch. megalotis.

Schizostoma behnii, Peters, MB. Akad. Berl. 1865, p. 505. 

 Larger than any of the preceding species, but with comparatively 

 shorter ears, the ear-conch being slightly shorter than the head, ex- 

 ternally flatly emarginate, and terminating in a lobule separated 

 from the outer margin by a shallow notch, as in Sch. megalotis and 

 the other species. Horseshoe-shaped part of the nose-leaf well de-
