 tuberculate, bony nasal processes, which are directed down- 

 wards and slightly outwards. 

 Total length 87 centimetres. 



Ranajlavicrus. 



Vomerine teeth in two short transverse series just behind 

 the level of the choan^e. Head moderate, as long as broad ; 

 snout subacuminate, truncate at the end, as long as the 

 diameter of the orbit ; nostril near the end of the snout ; can- 

 thus rostralis angular ; loreal region concave ; interorbital 

 space a little narrower than the upper eyelid ; tympanum 

 distinct, nearly as large as the eye. Fingers and toes slender, 

 the tips dilated into small disks ; first finger not extending 

 quite so far as second ; toes nearly entirely webbed ; subar- 

 ticular tubercles small ; a small inner metatarsal tubercle. 

 The tibio-tarsal articulation reaches beyond the end of the 

 snout ; tibia as long as the vertebral column. Skin smooth, 

 belly and anal region granular; no dorso-lateral fold. Dark 

 olive-grey above, with a few scattered minute white dots and 

 a paler grey dorso-lateral band, bordered below by a blackish 

 lateral band passing through the tympanum ; lips pale grey,

A single male specimen. 



Rana redimita. 



Vomerine teeth in two small groups far behind the level of 

 the choanee. Head moderate ; snout subacuminate ; canthus 

 rostralis angular ; loreal region concave ; the diameter of the 

 orbit equals its distance from the nostril ; interorbital space 

 as broad as the upper eyelid ; tympanum distinct, nearly two 

 thirds the diameter of the eye. Fingers and toes moderate, 

 the tips dilated into small disks ; first and second fingers 

 equal ; toes half-webbed ; subarlicular tubercles moderate ; 

 a small inner metatarsal tubercle. The tibio-tarsal articula- 

 tion reaches the eye ; tibia three fourths the length of the 

 vertebral column. Skin smooth, granular on the belly and
