siioul; than tlie eye. Eyes on the iipjier surface of the body, 

 nearer the end of the snout than the spiraculum ; a well-marketl 

 lachrymal gland from the eye to the nostril ; the distance between 

 the eves twice as great, or rather more, than the distance between 

 the nostrils and much greater than the width of the mouth. 

 Spiraculum on the left side, directed 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 between three and four times as 

 long as deep, acutely pointed, the tip being inclined upwards in 

 life ; upper crest convex, about equal in depth to the lower ; the 

 upper crest does not extend on to the back. Depth of the 

 muscular portion of the tail at its base rather more than half 

 greatest total depth of tail. 



Beak broadly edged with black. Sides and lower edge of the lip 

 bordered with papillEB. Upper lip with six series of line teeth, 

 the u]))ier uninterrupted, the remainder broadly interrupted, 

 decreasing in length towards the beak, the sixth or inner series in 

 some specimens being very small or absent. Lower lip with four 

 long series of teeth, the inner very narrowly interrupted, the 

 remainder uni uterrupted . 



Uolour. The larva till it reaches a total length of from 35 to 

 40 mm. is blackish-brown above, white beneath, with a grey 

 mottled tail ; after this the upper parts are a warm-brown, 

 mottled with darker brown, and the sides and lower parts yellow 

 also mottled with brown, but the skin of the underneath of the 

 abdomen is transparent and of a purjjle colour ; the tail is mottled 

 brown and yellow ; the hind legs of the tadpole are grey marbled 

 with black, when the fore legs appear the back assumes the bright 

 chocolate colour of the adult frog. The iris is golden, and the eye 

 bright and noticeable. 



Size. Length of body 24 mm. Length of tail 44 mm. Depth 

 of tail 12 mm. The largest tadpole, without hind legs, I observed 

 was 70 mm. in total length ; the largest, with hind legs but 

 without fore legs, was 77 mm. The recently transformed young 

 measure about 25 mm. from snout to vent.
