 1 Mediterranean; coll. Herr G. Schwartz von Mohrenstern [as "Alv,

46. Alvania n sp. 

 Long. 4, diam. \\ mil. 



2 Hongkong; coll. R. Huugerford, Esq. 



Goald's description of -4ZiYm/rt /t(5ca, from Hongkong, would 

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

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

 only five and a half whorls. 



47. Alvania [?] asturiana. 



Plagiostyla asturiana, P. Fischer, Act. Soc. Lin. Bord., XXIX, 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., IS 60, type F. pupoides, A. Ad., as " Finella," emend. 1864. 



The Bissoa semicostata, Pease, A. J. C, 1868, Caroline Inl., 

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

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

 ferrtiginea, 1860, all from Japan.
