REPTILES AND BATRACHIANS FROM BURMA 341 



This genus stands in the same relation to Ixalus as Chiro- 

 mantis to Rhacophorus. 



27. Oliirixaliis doriae , sp. n. 



{PL X, fig. 5). 



District of the Karin Bia-po : five specimens ; Thao : one 

 specimen. 



Snout rounded or obtusely pointed, shorter than the diameter 

 of the orbit ; canthus rostralis obtuse ; loreal region nearly ver- 

 tical, concave; nostril nearer the tip of the snout than the eye; 

 interorbital space broader than the upper eyelid; tympanum 

 half the diameter of the eye. Inner fingers webbed at the base, 

 outer one third webbed; toes two thirds webbed; disks of fingers 

 as large as the tympanum, of toes smaller ; subarticular tuber- 

 cles well developed ; a small inner metatarsal tubercle. The 

 tibio-tarsal articulation reaches the eye, or between the eye 

 and the nostril. Skin smooth , finely granular on the throat , 

 coarsely on the belly and under the thighs. Yellowish or pur- 

 plish-grey above , uniform or with small blackish spots and 

 three dark stripes along the head and back; lower parts white. 

 Male with an internal vocal sac. 



From snout to vent 34 millim. 



PHRYNODERMA, g. n. 



Pupil horizontal. Tongue oval, free and very feebly nicked 

 behind. Vomerine teeth none. Tympanum distinct. Fingers and 

 toes webbed, the tips dilated into large disks. Outer metatarsals 

 separated by web. Omosternum and sternum with a bony style. 

 Terminal phalanges bifurcate; an intercalary ossification between 

 the two distal phalanges. 



The new frog for which this genus is established is Ranoid 

 in structure and bears considerable resemblance to Rhacophorus 

 leprosuSj, Tsch. But the shape of the tongue and the absence of 

 vomerine teeth necessitate the establishment of a new ^enus.
