Show 1899.] BATRACHIANS OF THE MALAY PENINSULA AND SIAM. 889 black pupil, remainder pale golden finely speckled with black, a broad horizontal line and a narrow perpendicular line forming a black cross on the eye. Size, d • Snout to vent 120 mm.; width of head 48 mm. ; leg 183 mm. 2 • Snout to vent 88 mm. : width of head 30 mm. These measurements are from Perak specimens, Penang ones attain an equal size. Singapore specimens reach snout to vent 165 mm. ; width of head 76 mm. (P. Z. S. 1896, p. 901). Distribution. Upper Burma, Tenasserim, Malay Peninsula, Sipora (Mentawei Islands), Java, Lombok, Flores, Natunas, Borneo, Philippines. Tadpole. In March 1898 I found tadpoles of this species iu the clear, swift hill-streams of Penang, about 1900 feet above sea-level; they frequented the edges of the stiller pools. They are typical Rana tadpoles in habits and appearance ; the mouth, I find on comparing my drawing with the figure by Boulenger (P. Z. S. 1891, pl. xiv. fig. 1 a), seems similar to that of R. esculenta. Description, of the Tadpole. Length of body about once and a half its width, about half the length of the tail. Nostrils about halfway between the eyes and the end of the snout. Eyes on the upper surface of the body, nearer the end of the snout than the spiraculum, the distance between the eyes once and a half to twice as great as that between the nostrils, and slightly greater than the width of the mouth. Spiraculum on the left side, pointing backwards and upwards, nearer the anus than the end of the snout, visible from above and from below. Anus opening on the right side, close to the lower edge of the subcaudal crest. Tail about four times as long as deep, acutely pointed ; upper crest convex, slightly deeper than lower, not extending to base of tail; the depth of the muscular portion of the tail, at its base, about T^- of the greatest total depth. Mouth, Beak broadly edged with black. Sides and lower edge of the lip bordered with papilla?.; upper lip with a long series of teeth, followed on each side by a short series of very fine teeth. Lower lip with three series of teeth: 1st very short, weak and uninterrupted; 2nd also uninterrupted; 3rd longer, narrowly interrupted and stronger than the two outer rows. Colour (in life). Above light reddish brown, of exactly the same colour as the sand on the bed of the streams they inhabit, mottled in places with darker brown ; a dark brown line through the eye, sometimes other dark lines radiating from the eye. Crests and posterior portion of muscular portion of tail colourless, with |
