 Baxter, aud 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. scabro, 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. R. Hungerford, Esq. 

 6 Kathiawar; coll. F. Fedden, Esq. 



4. Penella sp. 



2 Hongkong ; coll. R. Hungerford, Esq. 

 Something like F. reticulata, A. Adams. 



5. Fenellasp. 



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. 



Rissoa virgatu, Philippi, Zeits. Mai. 1849, Suez, Aden, SfC, and Descr. 

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



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

 his F. fupoides ?
