46. Alvania n. sp. 

 Long. 4, diam. If mil. 



2 Hongkong; coll. R. Hungerford, Esq. 



Gould's description of Alvania fusca, from Hongkong, would 

 answer perfectly to this form, but is said to have eight whorls 

 and measure long. 5, diam. 1J mil. Dr. Hungerford's shell has 

 only five and a half whorls. 



47. Alvania [?] asturiana. 



Plagiostyla asturiana, P. Fischer, Act. Soc. Lin. Sord., XXIX, 1869, [?] and 

 Fonds de la Mer, pi. II, fig. 5, 1872, Gulf of Gascony ; sect. Plagiostyla. 



1 Gijon, Bay of Biscay; coll. Marquis de Folin. 



If M. Fischer had made this remarkable species the type of 

 his Genus Plagiostyla, instead of R. lactea, Michaud, I should 

 have considered the form as worthy of at least subgeneric 

 distinction. 



Genus FENELLA, A. Adams. 

 Ann. Mag., I860, type F. pupoides, A. Ad., as " Finella," emend. 1864. 



The Eissoa semicostata, Pease, A. J. C., 1868, Caroline IB!., 

 3, 1|, seems to belong here H A. Adams has also described F. 

 Candida, 1861; F. asperulata, 1860; F. pulchella, 1860; F. 

 ferruginea, 1860, all from Japan.
