 Baxter, and G. Nevill, Esqrs. 



I am not clear whether this is, or is not, a distinct species 

 from the preceding [F. cerithina'] ? They seem to me to run 

 one into the other ! Certain it is, however, that Mr. A. Adams 

 identified as F. scabra, indubitable specimens of F. cerithina, 

 which had been dredged by Mr. Me Andrew at Suez ! The sculp- 

 ture of the Japan forms appears somewhat coarser, and with 

 one transverse stria less. 



10 Hongkong ; coll. E. Hungerford, Esq. 

 6 Kathiawar; coll. F. Fedden, Esq. 



4. Fenella sp. 



2 Hongkong ; coll. R. Hungerford, Esq. 

 Something like F. reticulata, A. Adams. 



5. Fenella sp. 



3 Hongkong; coll. R. Hungerford, Esq. 



6. Fenella [?] n. sp. 



1 Andamans ; coll. G. Nevill, Esq. 



Probably one of the most minute marine Mollusca in exist- 

 ence. 



7. Fenella virgata. 



Eissoa virgata, Philippi, Zeits. Mai. 1849, Suez, Aden, fyc., and Descr. 

 de I'Egypte, pi. Ill, fig. 29, long. 2. 



This is almost certainly one of A. Adams' species, perhaps 

 his F. pupoides ?
