tubercle ; toes not webbed. A fold of the skin runs from the 

 superciliary margin along the middle of the side towards the 

 inguinal region, separating the pink coloration of the back 

 from the dull yellowish of the lower parts. Upper parts sub- 

 symmetrically marbled with light brown ; two or three pairs 

 of whitish dots edged with black on the back, the most con- 

 stant being that corresponding to the extremities of the sacral 

 apophyses. The front pair are minute, between the eyes ; 

 others, very minute, are scattered in the coccygeal region. 

 Sides of the head blackish. Young specimens nearly uniform 

 pink above.

M. Grandidier has most kindly allowed me to examine the 

 specimens of Callula (and other reptiles) recently named by 

 him ; he himself has expressed his doubts as to the propriety 

 of referring these frogs to the Indian genus Callula, in which 

 I fully agree with him. They are undoubtedly adult speci- 

 mens of his highly interesting genus DyscopJms (a Discoglos- 

 soid). Singularly enough the discovery of Callula notosticta 

 reestablishes the fact that Callula, or at least a form most 

 closely allied to it, really occurs in Madagascar.
