Rana tytleri (Theobald). 

 (Plate II, figs. 3, 3a.) 



Tadpole moderately large, but of graceful shape ; head and body 

 narrowly ovoid, flattened above but not depressed ; snout rather broadly 

 rounded, slightly declivous ; eyes lateral, but situated close to the dorsal 

 surface ; nostrils situated nearer the tip of the snout than the eyes, 

 the distance between them much less than the interorbital space or the 

 distance from eye to nostril. Spiracle tubular, directed upwards and 

 backwards, situated much nearer eye than to posterior extremity of 

 the body ; throat somewhat flattened, abdomen convex. 



■ Mouth-disk small, pointing forwards rather than downwards, dis- 

 tinctly transverse ; the upper lip nearly straight, edged with teeth : 

 the lower lip with a distinct lateral lobe on either side, which is con- 

 stricted in the middle ; the lateral lobes edged with rather broad and 

 blunt papillae, which extend inwards at the constriction ; the posterior 

 lobe fringed with two rows of finger-like processes, which are interrupted 

 for a short distance in the middle ; dental formula 1 : l-|-l/3 or 

 1 : l-f-l/l-j-l : 2 ; the anterior tooth-row relatively broad ; the two 

 halves of the divided row on the upper lip very short and widely separ- 

 ated ; first and second rows on the lower lip sub-equal, third row much 

 shorter ; the first row on this lip very shghtly interrupted, perhaps 

 by accident ; beak wide and shallow, both the upper and the lower 

 parts white, with black edges ; the middle part of the upper beak almost 

 straight. 



Tail powerful, of graceful shape, sharply pointed, with both mus- 

 cular and membranous portions well-developed ; dorsal membrane 

 arising well in front of the posterior extremity of the body, the dorsal 

 and ventral margins almost straight and parallel for the first half of their 



1 Possibly these specimens represent a distinct local race.
