POLYPEDATES. 427 



Hylorana temporalis. (Plate XXVI. fig. G.) 



Hylarana malabarica, Kelaart, Prodr. Faun. Zeyl. i. p. 191. Giinth. Batrach, Sal. pp. 131 & li^i 

 (uot synon.). 



Of moderately slender habit. Head with the snout scarcely elongate, and with angular 

 canthus rostralis; upper jaw slightly prominent beyond the lower; loreal region longitudi- 

 nally concave ; eye large, larger in circumference than the tympanum. Limbs moderateh' 

 slender ; disks of the fingers and toes well developed ; fingers long, the first and fourth nearly 

 equal in length and longer than the second. The length of the body equals the distance 

 between vent and heel ; toes of moderate length, the length of the fourth being a little less 

 than one-half of the length of the body in full-grown specimens, and a little more in young 

 ones. The interdigital membrane is broad, extending to the tips of the fifth and third toes ; 

 metatarsus with two tubercles, one at the base of the first finger being larger than the other 

 and oblong. Skin smooth : a linear, quite rudimentary fold of the skin runs from the hinder 

 angle of the orbit along each side of the back ; no glands behind the angle of the moutli. 

 Upper parts reddish- or yellowish-brown ; a subquadrangular deep-brown spot occupies the 

 space between the eye and humeral joint, covering the tympanum ; this spot is well defined 

 in adult specimens and edged with whitish, whilst in young ones it extends from the eye over 

 the entire side of the body below the lateral fold. A black streak edged with whitish runs 

 along and below the canthus rostralis ; an indistinct whitish line along the upper lip. Lower 

 parts whitish, throat and chest marbled with brown ; an oblong, oblique dark-brown spot 

 across the lower part of the humeral joint. Limbs with distant black cross bars. 



From a repeated comparison of our specimens of this species with the description of 

 Dumeril's R. malabarica, it appears to me very probable that the Ceylonese frog is difterent 

 from that of the Continent. The former has a somewhat different, but constant, coloration ; 

 its interdigital web is broad, the fourth toe is only one-third longer than the third and fifth, 

 and, finally, its hind limbs are longer by the length of the whole tarsus. AVe have received 

 it from Ceylon only. 



Length of body 3 inches, of hind limb 5 inches, of fourth toe 1 inch 3^ lines. 



POLYPEDATES, Dim. Sf Bihr. 



Skin smooth, rarely with tubercles ; no glandular fold on the side of the 

 back, a short fold from behind the eye above the tympanum. Vomerine 

 teeth present (in adult specimens). Tongue elongate and deeply notched 

 behind. Tympanum more or less distinct. Limbs of proportionate length ; 

 fingers shortly webbed, or free ; toes broadly webbed. Disks well developed. 



The arboreal habits of these frogs are indicated by the development of the terminal disks 

 of their fingers and toes. They are found in almost every part of the East Indies and in
