On the Distribution of the Fossils described by Messrs. d'Archiac 

 and haime in the different tertiary and infra-tertiary 

 Groups of Slnd, by F. Fedden, a.r.s.m., f.g.s., Geological Survey of 

 India. 



In the process of examining the several collections made during the 

 progress of the Survey in Sind, I have been able to identify a large pro- 

 portion of the fossils figured by Messrs. d'Archiac and Haime in their 

 " Description des Animaux fossiles du groupe Nummulitique de I'Inde" 

 and so to determine their position in the series. 



It had hitherto been impossible, as has been shown in the preceding 

 paper on the Geology of Sind, to tell from which particular horizon the 

 fossils described by d'Archiac and Haime were obtained. It now appears 

 that, instead of these fossils being exclusively Eocene, some are older 

 and many newer, a large proportion being Miocene. A list giving the 

 distribution would evidently be a necessary sequel to the great French 

 work, indeed this was pointed out by the authors themselves. The 

 following table will serve provisionally toward that end, until the whole 

 collection can be taken in hand by an experienced palaeontologist. 



The identifications of the Nummulites and some of the other Fora- 

 minifera have been confirmed by Professor Rupert Jones : Mr. Blanford 

 has examined and verified many of the Echinodermata and Mollusca ; it 

 was intended that we should go through the whole together, but want 

 of time has prevented his doing so. 



In the following table both Corals and Bryozoa are omitted ; the 

 former are now being examined by Professor Martin Duncan for publi- 

 cation in the " Palaonlologia Indica ;" the Bryozoa have not yet received 

 specific attention. Those fossils in d'Archiac and Haime's list that 

 came from other parts of India and have not been met with in Sind, are 

 also omitted in the list below ; neither have I entered any genera or species 

 not mentioned in d'Archiac and Haime's work, deeming it undesirable to 

 complicate the present table. It should be borne in mind, therefore, that 

 this is by no means a complete list of the fossils already determined ; and 

 that there are many new species yet to be described and named.
