This is an interesting addition to Mr. W. Blanford's genus Cya- 

 thopoma, the other species being confined to India, with the excep- 

 tion of C. deccanianum, of which I obtained a specimen from Sir 

 David Barclay, found by him in the garden attached to his residence 

 at Mauritius, where, however, it has probably been introduced.

This curious httle shell was found by Mr. Hugh Nevill on coral, 



and in texture resembles the shell of Leptoco7ichus. It is probable 



that the Hyula abnarmis of Gould is closely allied, and will form a 



second species of the genus.
