344 MR. W. L. SCLATER ON SPECIMENS OF [May 3, 



Described from a single specimen in the Indian Museum, procured 

 by the late Dr. Jerdon in the Khasia hills in Assam. 



5. Rana hascheana, Stoliczka, Journ. As. Soc. Bang, xxxix. 

 1870, p. 147, pi. ix. fig. 3. 



An examination of the type of this species preserved in the 

 Indian Museum shows that it is nearly allied to R. dories, Boulg. 

 The general shape is the same, the legs are about the same length, 

 and the vomerine teeth commence on a level with the hinder edge 

 of the choanae. The only real distinction is in the toes, which in 

 72. dorice are webbed to the tips, but in R. hascheana for only about 

 one- third of their length.

6. Rana limborgi, sp. u. (Plate XXIV. figs. 3, 3 a.) 



Vomerine teeth in two oblique groups, commencing on a level 

 with the choanse and extending well behind them ; slight traces of 

 the bony prominences of the lower jaw ; head moderate ; snout 

 short, hardly longer than the diameter of the orbit ; canthus ros- 

 tralis very rounded, hardly marked ; loreal region almost flat ; 

 nostril about equidistant from the tip of the snout and the front of 

 the orbit ; interorbitul space as broad as the upper eyelid ; tym- 

 panum distinct, nearly as large as the eye, with a very thick fold 

 above it ; first finger extending slightly beyond the second ; toes 

 moderate, slender, only about a third webbed, the web extending 

 only about halfway up the first joint of the digits ; a slight cuta- 

 neous ridge along the fifth toe ; tips of fingers and toes but very 

 slightly swollen ; subarticular tubercles fairly well developed ; no 

 outer metatarsal tubercle ; a large, compressed, fairly sharp-ridged 

 inner metatarsal tubercle, very nearly as large as the inner toe; 

 traces of a tarsal fold present ; the tibio-tarsal articulation reaches 

 the nostril ; skin above granular, with slight traces of a granular 

 lateral fold running back on either side from behind the eye and a 

 transverse fold between its posterior borders ; below smooth. 



Colour above a faded olive-brown, below lighter. 



Length from snout to vent 24 millim. 



This species is somewhat intermediate between R. dorice and 

 R. rufescens ; from the former it differs in having only very slightly 

 webbed toes and a compressed flattened metatarsal tubercle, and 

 from the latter in its vomerine teeth, which commence only on a 

 level with the posterior corners of the choanee, and from both in 

 the presence of its rudimentary glandular lateral fold. 



This description is taken from a single specimen procured in 

 Tenasserim by Mr. Limborg, to whom I have dedicated the species. 



7. Rana tigrina, Daud. ; Boulenger, Ind. Rept. p. 449. 



A small Frog from Penang, described by Stoliczka ( Journ. As. Soc. 

 Beng. xxxix. 1870, p. 142) as R. gracilis, var. pulla, seems to be 

 merely the young of B. tigrina ; that the type has only just lost 

 the larval tail is shown by the persistence of the tail-scar.
