in the Collection of the British Museum. 349 



two papers on the same subject in this Journal*. The total 

 number of species in that Collection is now 745, and that of 

 the typical specimens 260. 



This considerable increase, within the period of less than a 

 year, is partly caused by the particular attention which the au- 

 thor has paid to the herpetology of the East-Indian continent. 

 The descriptions of the new species belonging to that fauna will 

 be found in his forthcoming work on this subject, published by 

 the Ray Society.
