Show 890 ON THE FROGS OF THE " SKEAT EXPEDITION." [Dec. 4, during the month of June, in a stream with a gravelly bed. They are provided with a very remarkable funnel-like float, formed by tbe lips, which are fused together at the angles of the mouth. This funnel is much wider than it is long, and opening dorsally at its wider end leads down to the mouth, which is subterminal and faces ventrally as in other tadpoles. The " buccal vestibule " so formed has on its inside rows of minute widely separated denticles. By means of it the tadpoles can apparently float motionless, hanging as it were from the surface of the water by their lips. The total length of the largest individual obtained by Mr. Annandale is 31 mm., the length of the head and body 8-5, and the breadth of the funnel-opening 7, the length about 3 m m . A fuller account of this interesting creature, with figures, is ghen by Prof. M a x Weber in the ' Annales du Jardin Botauique de Buitenzorg,' 1898, Supplement ii. pp. 5-10.

Fairly common on Gunong Inas from a height of 3000 ft. upwards. I caught two females and a male which is much smaller than the females. This species is much more active than either of the preceding members of the genus. The measurements of the larger female are :- Snout to vent 62 mm.

Mr. Annandale collected numy specimens, adult and youin^, at a small village near Biserat. The natives told him that they were found only iu places where ants were not very plentiful. The Siamese speaking natives call them " N g u kling (? pling)," and the Malays " Ular Belugelengong,'' or sugar-mill snake. EXPLANATION OF PLATE LVII. Figs. 1, 2. Rana lateralis, p. 886. Fig. 3.
