2. The tail is a little longer in proportion to the head and body, 



its length being more than five times its greatest depth. 



3. The upper lip is relatively much broader, being more than three 



times the breadth of one of the lateral lobes of the lower lip, 



4. The beak is relatively broader and stouter. 



5. The markings are less conspicuous and the ventral surface is 



colourless. 



Mr. Gravely obtained a complete series of this larva, with many 

 young frogs, in the same circumstances as those in which he found the 

 tadpoles of R. leptodactyla and R. verrucosa.

The tadpoles are of moderately large size ; the head and body rather 

 narrowly oval, flattened moderately, the ventral surface being distinctly 

 convex ; the snout is rounded, the nostrils rather widely separated, 

 nearer to one another and to the eyes than to the tip of the snout, the 

 distance between them being much more than half the interorbital 

 breadth ; the eyes are dorsal but directed outwards, situated at about 

 one-third the distance between the tip of the snout and the base of 

 the hind limbs. The spiracle is lateral, sinistral, somewhat tubular, 

 pointing upwards and backwards. 



The mouth-disk is large and somewhat sucker-like, entirely ventral, 

 but with opposible lips and a lateral emargination on either side. The 

 lower lip is edged with minute finger-like processes, the lateral region 

 of the disk, which is produced in two lobules, is densely covered with 

 similar processes ; the upper beak is shallow, broadly U-shaped, 

 entirely black, with smooth or almost smooth margins, the lower 

 beak much narrower, V-shaped, distinctly but minutely serrated on 

 the margins, white at the base for at least half its depth. The dental 

 formula is 2 : 5+5/1 + 1 : 5, the three upper tooth-rows being equal 

 and the interruption in the third being very slight ; the five upper tooth- 

 rows of the lower lip are equal and the sixth rather shorter ; the 

 interruption in the first row of this lip is very slight. 



The tail is long and slender, narrowly lanceolate, the muscular part 

 relatively deep in the middle, the whole tapering to a fine point ; both 

 membranes arise a considerable distance behind the base of the hind 

 limbs. 



The dorsal and lateral surfaces of the head and body are purplish- 

 brown with a few dark spots, becoming paler between the eyes, the 

 ventral surface yellowish, the proximal third of the tail brown with a few 

 dark spots, the distal two-thirds as a rule more deeply pigmented, 

 marbled with purplish-brown and buff or almost entirely of the former 

 colour, the membranes bearing scattered pigment-cells.
