XXIV. — Natural History Notes from H.M. Indian Marine 

 Survey Steamer ' Investigator^^ Commander T. H. Heminq, 

 B.N. — Series III., No. 1. On Mollusca from the Bay of 

 Bengal and the Arabian Sea. Bj EdgAR A. Smith. 



The present paper contains merely descriptions of some of 

 the new species obtained by tlie ' Investigator ' during the 

 season 1897-98. It seems advisable to publish them now, as 

 Dr. Alcock, Superintendent of the Indian Museum at Cal- 

 cutta, wishes the types to be returned as soon as possible for 

 the purpose of figuring them in the ' Illustrations of the 

 Zoology of the * Investigator '.' 



The continuation of this paper will contain a complete list 

 of all the Mollusca collected during the above-mentioned 

 season, with descriptions of additional new species. 



I regret to say that examples of only seventeen of the 

 thirty-five species now described can be retained for the 

 collection of the British Museum, as all unique specimens 

 have to be returned to the Indian Museum.
