 len^'th of the hiiul loot. While of nearly tln^ same leii<;th, the foro 

 limbs are not more that hall' as thick as the hin<l lind)s. Their len^'th 

 is just e<|ual to tint distance I'roiu the axilla to the end of the mu//,le. 

 The scitond (first) lin;ier is very small, with but a rudiment free. The 

 third lin};('r is Ion*;', ainl the fouitli still longer, while the iifth is lon;;er 

 than the second (lirst), but <;('ncrally less than half as lonj-as the fourth.

The lirst and tilth Iocs are mere obtuse rudiments and of e(|ual length. 

 The other toes ai'c not iclalivcly so Ion;;' as the tiuji'crs, standin,n 2-\-'.i

 especially the inte;;iiment of the inner side. It is then divided by tiaiis- 

 verse folds, and the portions between them become corneous oi' chit- 

 inous. There are thus Irom ten to twelve transv»^rse jdales on the in- 

 side of the thij^lis, and an irregular nuinbi'r on the inside of the tibiii 

 and tarsus. The iiidimcntal external and internal toes have a (!ap of 

 the same substance. These bodies aid the male in maintaining- his hold 

 on the female during copulation. 



The skin in the form Viridcscens is smooth on all the surfa(;es, but 

 ralln-r closely wriidilcd. The tail has a free dermal margin or tin (of 

 about etpial width and length) on both the superior and the inferior 

 edges. The genitalia arc very prominent at the breeding season, and 

 in the male t orilicu' is oval. It is very papillose, especially within 

 till' anterior liorder. (See Plates '6\i and 11, tig. .'{.) There is i.o trans- 

 verse postgular fold, and there arc no transverse lateral grooves.
