M. Grandidier has most kindly allowed me to examine the 

 specimens of CaUula (and other re])tiles) recently named by 

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

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

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

 mens of his highly interesting genus Bf/scojy/ncs (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.
