[b) Tadpoles. 



The tadpoles here discussed are those of : — 



A. Rana liehigii, D, Rhacophorus maculatus, 



B. Rana alticola, E. Phrynoderma moloch, 



C. Rana afghana, F. An unidentified Ranid, 



G. and H. Megalophrys, spp. 



Fam. RANID^. 

 A. Larva of Rana liEbigii, Giinth. (Plate iv, fig. 2.) 



Annandale, J .A.S.B., 1906 (2), p. 290. 



The tadpole of this species is very abundant in small jungle 

 streams in the neighbourhood of Kurseong (4,000 — 5,000 ft.), 

 E. Himalayas, both in April and ;\Iay and in Jul}-, August and 

 September. Mr. Kemp obtained two specimens in a small stream 

 on the east side of the Dihang R. near Yembung between the 13th 

 and the 17th of January. Their hind legs were just beginning 

 to appear. 



The larva of R. liebigii may be redesciibed as follows : — 



Head and body feebly arched above but not quite flat, sloping 

 slightly from behind forwards, convex on ventral surface, broadly 

 ovoid as seen from above ; the tip of the snout rounded. 



Mouth ventral; lips broad but not excessively so, directed 

 inwards and enclosing a considerable cavity ; posterior lip directed 

 backwards, anterior lip forwards and inwards, thus forming a 

 vestibule to the mouth ; lower lip with a complete double row of 

 rather elongate tubercles ; upper lip fringed with a single row of 

 rather smaller tubercles which is widely interrupted in the middle ; 

 dental formula usually 2: 5-I-5 | i + i-: 2,' sometimes three un- 

 interrupted rows of teeth present on the upper lip ; neither upper 

 nor lower beak divided ; both horseshoe-shaped and minutely 

 serrated ; upper lip very narrow. 



Nostril and eye small, by no means prominent; the former 

 situated midwa}- between the eye and the tip of the snout ; eye 

 directed obliquely upwards, situated at the junction of the dorsal 

 and the ventral surfaces, much nearer the tip of the snout than 

 the base of the tail. 



Glands. — ^None apparent. 



Spiracle sinistral, pointing backwards and slightly upwards, 

 small, circular, not markedly tubular. 



Vent dextral. 



^rt^7 gradually pointed, tapering, twice as long as head and 

 body ; its greatest depth \ of total maximum length ; fin-mem- 



1 For convenience in printing this and other dental formutae in this paper 

 are printed in a somewhat novel form. The figures to the right of the central 

 dark vertical line represent the tooth-rows of the upper, those to the left of this 

 line the tooth-rows of the lower lip. The colons merely separate the number of 

 undivided from that of divided rows.
