NOTICE 



When the Palseontologia Indica was begun, no rule seems to have been fixed as to 

 what should constitute a ' Series.' A change of authors or a very partial change of 

 subject was considered suflBoient for a change of series, and so the numbers rose 

 to XIV. After 1880 the whole were arranged into the seven natural groups, as 

 now indicated on the covers of the Survey publications ; but to avoid confusion no 

 renumbering was introduced, each will be continued under the highest series-num- 

 ber attained within that group. Thus, in the present volume, Dr. Stoliczka's short 

 paper forming series VII had to be linked with the greatly more extended work of 

 Dr. Martin Duncan and Mr. Percy Sladen begun as series XIV. The tertiary fossils 

 will form by far the most extensive series of the Indian region, and it will be a 

 question for future consideration whether all should not be brought within this series, 

 under a slightly expanded title ; but as the tertiary rocks of Western and of Eastern 

 India are widely separated it may be thought better to keep the description of the 

 latter permanently distinct.
