INTRODUCTION. 



These species, although they may be found afterwards somewhere 

 else in Burma or in India, are for the present of no use in ascertaining 

 the age of the strata in which they occur, and they may therefore 



be left alone. 



As regards the 28 species which have previously been described, 



they are the following:— 



1. Paracyathus caruleus, Duncan 



2. Eupsamtnia regalis, Alcock. 



3. Daphnderma ceslata, Reeve 



4. Corbula harpa, Sow. . 



5. Solarium afflne, Sow. . 



6. „ cyclostomum, Menke 



7. Scalaria subtenuilamella, d'Arch 



8. Turitella affinis, d'Arch. 



9. Natica obscura, Sow. • 



10. „ callosa, Sow. • 



11. Strombus nodosus, Sow. . 



12. Cyprcea gra iti, d'Arch. . 



13. Trivia smithi, K. Martin • 

 $4. Triton davidsotti , d'Arch. . 



15. Ranella tubercularis, Lam. 



16. Nassa cautleyi, d'Arch. 



17. Clavella djocdjocarta % K. Mart 



18. Fasciolaria nodosa^ Sow. sp.

It may be seen at the first glance that this fauna cannot be consi- 

 dered of any earlier than miocene age ; there are only three species 

 which so far have been noticed to occur in older strata, viz % :— 



Daphoderma calata, Reev, 

 Corbula karpa, Sow. 

 Fasciolaria nodosa, Sow. sp,
