890 OX THE TltOGS OF THE " SKE.VT EXPEDITION." [Dec. 4, 



during the mouth of June, in a stream with a gravelly bed. They 

 are provided with a very remarkable funnel-like float, formed by 

 the 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 tbe surface of the water by their lips. 

 The total length of the largest individual obtained by Mr. Annan- 

 dale is 31 mm., tbe length of the head and body 8*5, and the 

 breadth of the funnel-opening 7, the length about 3 mm. 



A fuller account of this interesting creature, with figures, is 

 given by Prof. Max Weber in tbe ' Annales du Jardin Botanique 

 de Buitenzorg," 1898, Supplement ii. pp. 5-10.

Mr. Annandale collected many specimens, adult and young, 

 at a small village near Biserat. The natives told him that they 

 were fouud only in places where ants were not very plentiful. 

 The Siamese speaking natives call them " Ngu kling (? pling)," 

 and the Malays " Ular Belugelengong,*' or sugar-mill snake.
