The tadpole is large ; the head and body massive but flattened, 

 broadly rounded in front, relatively very large ; the eyes and nostrils 

 are situated far back, the latter about half way between the hind 

 limbs and the tip of the snout ; the distance between the nostrils is 

 much less than that between them and the eyes, about half the inter- 

 orbital breadth ; the eyes are small, entirely dorsal ; the distance from 

 the tip of the snout to the nostrils is more than twice that from 

 nostril to eye. 



The ventral surface is flattened. The spiracle is sinistral, laterally 

 tubular, pointing upwards and backwards, situated rather nearer the 

 anus than to the tip of the snout. 



The mouth-disk is ventral, transversely oval, sucker-like, surrounded 

 entirely by a margin covered with small rounded tubercles, occupying 

 (when the mouth is open) about one-third of the ventral surface ; the 

 upper and lower lips are not opposible ; the dental formula is 2/3 or 

 2/1-f 1 : 2 ; the two upper tooth-rows are equal and a little longer 

 than the three lower rows, which are also equal ; the upper and lower 

 beaks are each in a single piece, rather shallow (especially the lower 

 beak), moderately stout, with their margins very minutely serrated ; 

 they are white with black margin. 



The tail is relatively short and feeble, shallow, sharply pointed ; the 

 fin-membranes moderate both above and below, each of about the same 

 depth as the muscular portion in the middle of the tail, the upper mem- 

 brane commencing some little distance behind the base of the hind legs. 



The colour of the dorsal and lateral surfaces is dark grey with small 

 black spots, the tail is marbled with dirty white ; the ventral surface 

 is colourless except for a few scattered pigment-cells. 



The anus opens by a transverse slit, which extends right across the 

 base of the tail on to a little flattened leaf-shaped membrane, which 

 extends backwards on the ventral surface and is situated to the right 

 of the middle line.
