152 Indian and Malayan Amphibia and Reptilia. [No. 2, 



thighs ; in the females, the lower parts are whitish, either uniform or 

 only slightly dusky. Fore limbs with few indistinct cross "bands, a 

 dark streak in front of the upper arm, and another one behind, as 

 well as on the lower arm ; hind limbs above banded with brown, 

 behind indistinctly mottled with dark and yellow. 



In coloration and in the development of the disks of the fingers and 

 toes, &c, this species much resembles H. temporalis, Gr ii n t h., (1. 

 cit. p. 425) from Ceylon. But in this species the hind limbs appear 

 to be in proportion longer, the snout is much broader, the third finger 

 shorter, and it is said to have " no glands behind the angle of 

 the mouth." In Tythri the lower glandular tubercle commences 

 between the tympanum and the upper angle of the mouth ; in Nico- 

 bariensis that tubercle is situated behind and rather almost below 

 the angle of the mouth. 



Fam. Ehinodermatidje apud Gf ii n t h e r. 



No maxilary or vomerine teeth ; ear and tympanum developed ; 

 toes webbed j sacral vertebra dilated ; no paratoids. 



Ansonia, n. gen. 



Body slender, elongated, rather depressed, uniform in width ; 

 sacral vertebra much dilated ; muzzle short, obtuse ; limbs long and 

 slender ; fingers four long, smooth, free and peculiarly cylindrical ; 

 toes five, not much developed, half webbed ; disks of fingers and 

 toes slightly swollen, rounded. 



The great peculiarity of this genus rests in the slender form of the 

 body and the great length and slenderness of the limbs, and especial- 

 ly of the fingers. In the general character it more reminds of 

 Phryniscus, than any of the genera of the Rhinodekmatid^e, referred 

 to this family by Gr ii n t h e r, but it is readily distinguished from 

 the former genus by the tympanum and open eustachian tubes. I 

 have associated with this new form, the name of my esteemed 

 friend, Col. Anson, the present Governor of Penang, who has 

 shewn the greatest interest in my natural history researches 

 during my short stay on the island.
