Pyxicephalus macrotympanum. 



Vomerine teeth in two oblique series between the choanse, 

 close to the inner borders of the latter. Head feebly depressed, 

 much broader than long ; snout rounded, as long as the orbit : 

 canthus rostralis obtuse, loreal region concave ; nostril a little 

 nearer the eye than the end of the snout ; interorbital space 

 nearly as broad as the upper eyelid ; tympanum distinct, 

 larger than the eye. Fingers extremely short, blunt, first 

 and second equal ; toes short, blunt, half webbed ; sub- 

 articular tubercles small ; a large, compressed, very pro- 

 minent but not sharp-edged inner metatarsal tubercle, its 

 length equalling that of the inner toe. Tarso-metatarsal 

 articulation reaching the tymjianum ; tibia two-fifths the 

 length of head and body. Skin smooth. Pale greyish 

 brown above, with dark brown dots, and a dark brown band 

 extending from the end of the snout, through tlie nostril and 

 eye, to the groin, where it breaks up into spots, and expanding 

 into a large blotch below the eye and on the temple ; a brown 

 line borders the upper lip ; lower lip with large brown 

 blotches ; lower parts white, with a few brown dots on the 

 throat. 



From snout to vent 55 mm. 



A single female specimen from Gallaland, west of the 

 Juba River, from the collection of Dr. Donaldson Smith. 

 Had been referred to Rana {Pyxicephalus^ ornata, Peters, 

 in P. Z. S. 1895, p. 540 ; differs from that species in the 

 broader head with more rounded snout and broader inter- 

 orbital region, and in the larger tympanum.
