specimens from the island of Nias, I am now able to add to 

 mj diagnosis that humeral glands are absent and the vocal 

 sacs internal.

This remarkable genus was established on the external 

 characters only. The following generic diagnosis, drawn 

 from the osteological chai'acters also, will supplement Bott- 

 ger's excellent description. 



Pupil horizontal. Tongue large, elongate, entire, free at 

 the sides only, longitudinally grooved. A non-interrupted 

 angular series of palatine teeth. A cutaneous fold across the 

 palate between the choange. Tympanum hidden. Fingers 

 and toes free, the latter with the tips slightly dilated. Outer 

 metatarsals united. Inner metatarsal tubercle very large. 



r 



Coracoids strongly dilated, directed a little backwards ; pre- 

 coracoids extremely feeble ; no oraosternum ; sternum large, 

 cartilaginous. Sacral vertebra with feebly dilated diapophyses, 

 articulated to coccyx by two condyles. Terminal phalanges 

 simple. 



In its skeleton Rhomhophi-yne approaches much nearer 

 Scaphioiohryne than Breviceps^ near which it was provisionally 

 placed. 



I take this opportunity to correct a serious error of Parker*, 

 which has recently been repeated by Sabatier f. The former 

 author has described and figured the sternal apparatus of two 

 *' species " of Breviceps, viz. Systoma gihhosiim, Wagl., and 

 S. granos7tm, Dum. (these names are synonyms), which are 

 said to differ from each other in having the elements of the 

 pectoral arch precisely reversed as to shape and relative size.
