ElTPREPES OLIVACEUS. 



The young (body 1 to 1*5 and tail 1*5 to 2 inches) are very differently 

 coloured from the old. The snout and headshields arc olivaceous, the pos- 

 terior edges of all the shields being blackish ; the whole bod}^ and limbs are 

 blackish brown, with numerous rather close, transverse, greenish white or 

 yellow stripes ; tail and the entire lower side yellowish white, or quite yel- 

 low. In the adolescent and some old ones the pale transverse bands exist 

 as remna.nts in the shape of transverse series of spots, but most adults become 

 entirely olivaceous, with only the edges of the eyelids bright yellow. 



GyMNODACTYLTJS PULCHEI/LTJS. 



In the descriptions of this species it is usually stated that there are six 

 dark, white edged bands across the body, but properly speaking the sixth 

 band is situated on the base of the tail. Fui'ther, it is stated that a fold of 

 the skin exists along the side of the body. Tliis is in reality not the 

 case, at least not in live specimens, but the shield-like scales of the lower 

 side are separated from the granular upper surface by a row of conspicuously 

 enlarged granular scales ; this row becomes strongly prominent in spirit 

 specimens, and gives the appearance of a fold. 



As regards the position of the femoral pores the species is intermediate 

 between Cyrtodactylns and Gymnodactylios^ the pores lying first in a long- 

 itudinal fold and then extending flatly on the femora. This instance shews 

 that Gyrtodactyliis, (as likewise the present species), should be looked upon 

 merely as a section of Gymnodactylus. 



DeACO QTJINQUEEASCIATrS . 



A single male specimen measures : head and body 3 '5 inch, tail imper- 

 fect, apparently about 5 inches. The hind limb is contained 1'33 times in 

 the distance between it and the fore limb, the latter being somewhat shorter 

 than the former. There are no enlarged tubercles on the head, but only a 

 number of interspersed, slightly larger white scales at the sides of the neck, 

 and a broad band of closer set ones across the occiput. The scales on the 

 anterior part of the back are obsoletely keeled, on the posterior part they are 

 perfectly smooth. On the wings scales are present along all the ribs, and in 

 numerous longitudinal series on the basal half of the alar skin, while further 

 on their number greatly diminishes, except again at the outer margin. 



The specimen has only a very slight indication of a crest on the neck ; 

 the gular sack is very long and lanceolate, a dark band running at its pos- 

 terior base across the lower neck. Chin dark spotted, like the body ; tail 

 also spotted at its base, but further on with brown bands. In all other re- 

 spects -the specimen agrees with Gray's characteristic description.
