equal length. Hind limb longer than the head and body ; laid 

 beside the body, the metatarsal tubercle reaches the end of the 

 snout. Metatarsus with a sharp-edged spur on the inner side and 

 a tubercle on the outer. Toes half-webbed, the tips slightly 

 swollen, and each of the joints on the under surface with a 

 tubercle. Third toe slightly longer than the fifth, fourth the 

 longest. Colour greyish, with a rufescent tinge. A dark brown 

 subtriangular spot on the occiput, extending from across and 

 behind the ej-elids, immediate!}' following which is a filiform 

 white vertebral streak, extending to the vent ; back with six 

 irregular-shaped dark brown spots. Plait behind the tympanum 

 reddish brown. Fore and hind limbs externally with transverse 

 bars of the same colour. Upper and lower jaws with vertical 

 bars of reddish brown. Chin, throat, and rest of under surface

Habitat. Malir, near Kurrachi (Karachi), Sind. 



Subgenus Nanorana. 

 Giimh., Ann. Mus. Zool. St. Pi-tersb. I, i8y6, p. 207. 



Vomerine teeth, if present, much reduced. No tympanum, 

 no stapes. Fingers and toes not dilated at the tips ; outer meta- 

 tarsals separated by web in their distal third or fourth only. 

 Zygomatic branch of the squamosal short. Omosternal style not 

 forked at the base. Terminal phalanges obtuse. 



I regard the single species of this subgenus as a dwarfed, 

 degraded form derived from the R. lichigii group, with which it is 

 connected to a certain extent by R. blanfordii.
