46. Alvania n. sp. 
Long. 4, diam. 1} 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. 13 mil. Dr. Hungerford’s shell has 
only five and a half whorls. 
47. Aivania [?] asturiana. 
Plagiostyla asturiana, P. Fischer, Act. Soc. Lin. Bord., XXTX, 1869, [?] and 
Fonds de la Mer, pl. 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., 1860, type F. pupoides, A. Ad., as * Finella,”’ emend, 1864. 
The Rissoa semicostata, Pease, A. J. C., 1868, Caroline Ial., 
3, 1}, seems to belong here? A. Adams has also described F. 
candida, 1861; F. asperulata, 1860; F. pulchella, 1860; F. 
ferruginea, 1860, allfrom Japan.
