Batrachia. 
FROGS OF THE RANA LIMNOCHARIS GROUP. 
In this group I include a number of comparatively small frogs, closely related to 
those of the Rana tigrina group, but distinguished by their less broadly webbed toes 
and by the presence of an inner metatarsal tubercle on the feet. So far as material 
before me renders a definite expression of opinion advisable, I believe that three s])e- 
cies may be distinguished, and also three local races subspecifically distinct from the 
true R. limnocharis. The three species are R. wasl, nov., R. limnocharis, Wiegmann 
and R. brevipalmata , Peters. 
R. wasl is a form intermediate between the two groups and has hitherto been 
confused with R. tigrina rather than R. limnocharis , to which it is allied in the struc- 
ture of its feet. The species occurs side by side with R. limnocharis in N. Borneo, 
Burma and Assam. The true R. limnocharis has a very wide range in south-eastern 
Asia, but has produced certain slightly differentiated local races in mountainous or 
insular districts. So far as is at present known these races are : — 
andamanensis (Stol.), which occurs, apparently to the exclusion of the typical 
form, in the Andaman Islands, but is also found occasionally on the main- 
land of Tenasserim ; 
greenii, Boulenger, from the hills of Ceylon; 
nilagirica, Jerdon, from the Nilgiris and the Shevaroy Hills in vSouth India. 
Rana brevipalmata was originally described from I^ower Burma. Boulenger was 
inclined to think that there was a mistake in the locality of the type-specimen, as he 
had only seen the species from the hills of south-western India ; but if the tadpole 
here assigned provisionally to R. brevipalmata is correctly identified, the form cer- 
tainly occurs in both parts of the Indian Empire. 
Rana wasl, sp. nov. 
(Plate V, fig. 5). 
1912. Rana tigrina, Aniiandale, Rec. Ind. Miis. VIII, p. 8 {nec. Daudiu). 
Size moderate; habit rather stout; head long, moderately narrow; snout narrowly 
rounded, upper jaw projecting slightly, ncstril much nearer tip of snout than eye, 
interorbital space much narrower than upper eyelid ; limbs moderate, length of the 
tibia about half that of the head and body. Feet about half webbed, outer meta- 
tarsal tubercle very minute, inner metatarsal fold present, but by no means strongly 
developed. Dorsal surface with short longitudinal ridges : small rounded warts or 
granules* present on the sides of the body and sometimes on the back, occiput and 
loreal region; a transverse fold often running across the dorsal surface of the head 
immediately behind the eyes. Ventral surface of head and body smooth, of sides 
somewhat granular. 
Colouration as in Rana tigrina except that there is no trace of parallel black 
and white stripes on the head and anterior part of the body. 
Type. No. 17282 (Rept. Reg. Z.S.I. ).
