Show 1871.] DR. J. ANDERSON ON INDIAN REPTILES. 209 POLYPEDATES MARMORATUS, Blyth, Journ. As. Soc. Beng. xxiv. p. 188 ; Gunther, I. c. p. 428. Polypedates afghana, Gthr.; Jerdon, Proc. As. Soc. 1870, p. 84. Habit rather stouter than P. maculatus. Snout of moderate length, not depressed, moderately pointed ; canthus rostralis distinct ; nostril slightly below the canthus rostralis ; loreal region rather deeply concave and granular. Eye large and prominent. Tympanum very small, smaller than the disk of the third finger. Vomerine teeth on two transverse ridges, on a line with the posterior margin of the choanae. Skin above densely covered with small tubercles, with white apices. A large white tubercle on the middle of the head between the anterior angle of the eyes; a few large glandular-like tubercles above the tympanum on the sides and behind the angle of the mouth. Belly and back of thighs finely tubercular. Fingers free, with the disks very large. Toes completely webbed, with the membrane extending to the disks; metatarsus with a small oblong tubercle. From the vent to the heel is considerably longer than the body. Colour (in spirit) pale yellowish, with large spots with black centres, paling towards the margins of the spots, so that they become confluent; a few white spots interspersed among them. Under surface yellowish, spotted with dusky on the chin, throat, and chest. Lips and limbs broadly barred with blackish, the barring on the legs extending on to the fingers and toes. Adult (Blyth's type), 3" 3'" in length; limb 5" /"'. Pegu. Adult (Darjeeling), 2" 8'" in length ; limb 5" 1'". Blyth's specimens were from Pegu; I also obtained it at an elevation of 3000 feet on the Kakhyen Hills, in the north-east of Burmah, on the confines of China; and other specimens are from the neighbourhood of Darjeeling, at an height of 3000 feet. POLYPEDATES HASCHEANUS, Stoliczka, Journ. As. Soc. Beng. vol. xxxix. p. 147, pl. ix. fig. 3. This is a small species, perhaps the smallest known form of the genus, measuring only 4f"> and the hind limb 1-rV'*- ^ n e head is rather large compared with the length of the body ; and its breadth is indicated by the circumstance that the distance between the eyes is nearly the length of the moderately long snout. The vomerine prominences are small rounded nodules, their anterior margins being almost on a level with the posterior margin of the choanae, from which, and also from one another, they are widely separated. Dr. Stoliczka describes an indistinct dorsal glandular fold on the fore part of body, which is clearly traceable on the posterior half of it. The existence of such a structure would lead us to refer this Frog to Hylorana and not to Polypedates ; but on carefully examining Dr. Stoliczka's specimens in this museum, I fail to detect the slightest indication of a dorsal glandular fold. The fold over the tympanum is well developed, and the disks of the fingers and toes are moderately large. PROC. ZOOL. Soc-18/1, No. XIV. |
