snout than the eye. Eyes on the upper surface of the body, 
nearer the end of the snout than the spiraculum; a well-marked 
lachrymal gland from the eye to the nostril; the distance between 
the eyes 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 papille. Upper lip with six series of fine teeth, 
the upper 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 uninterrupted. 
Colour. 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 purple cclour; 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 tail44 mm. Depth 
of tail 12mm. 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.
