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

 H. geographica, pardaUs, maxima, and langsdorfii , but is distinguished 

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

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

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

 and low fold along the fore-arm and the tarsus, 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 width. There are 

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

 of the body 2" ; length of front extremity 1^" ; length of hinder 

 extremity 3^".
