tips. Tips of fingers and toes dilated considerably into regular discs 

 Outer metatarsals separated from web. 



This genus seems most allied to Rhacopliorus, from which, how- 

 ever, it differs in possessing a vertical pupil and free fingers. From 

 Nyctibatrachus and Hylambetcs it differs in having a rounded tongue, 

 and from Cassina in having dilated toes. 



HELEOPHRYNE PURCELLI, gen. et sp. nov. 

 Plate, fig. 3, 3a. 



Snout obtuse, about as long as the orbital diameter, can thus 

 rostralis rounded, interorbital space a little broader than upper 

 eyelid ; tympanum not visible ; fingers free, ending in broad, flat, 

 somewhat truncate triangular expansions or discs. Toes completely 

 webbed and discs well developed, but not quite so large as those of 

 the fingers and less triangular ; subarticular tubercles oval and fairly 

 large, inner metatarsal tubercle oval and well developed, outer 

 absent. The tibio-tarsal joint reaches the end of the snout if the 

 hind limb be carried forward ; skin smooth above, granular beneath, 

 especially on the belly. 



Vomerine teeth in two linear groups between the choaiise, as in 

 Rana grayi ; maxillary teeth present ; tongue rounded behind. 



Colour (in spirit) purplish with darker round, faintly white edged 

 spots of the same colour ; hind limbs cross-barred with darker purple 

 bands below yellowish white. 



The type and unique specimen (No. 1313 of the Museum register) 

 was obtained by Dr. "W. F. Purcell in the Jonkers Hoek Valley 

 near Stellenbosch, and is now preserved in the Museum.
