Description of the sjoecimen. — This species has the physiognomy of 

 H. geo(jrapliica,imrdalis, maxima, and langsdorjii, but is distinguished 

 by the very short web between the fingers, the small tympanimi, the 

 coloration, and the small size. The tjanpanimi is half the size of the 

 eye, rather indistinct, obliquely elliptical ; there is a very narrow 

 and loAV fold along the fore-arm and the tarsiis, the latter being pro- 

 vided with a small appendage at the heel. The web between the 

 toes is deeply notched, and reaches only to the second phalanx of 

 the first to fourth toe. The coloration is as above described, the 

 black and white bars being nearly of the same 'nadth. There are 

 visible also some such bars on the upper side of the foot. Length 

 of the body 2" ; length of front extremity Ii" ; length of hinder 

 extremitj- 3^".
