68 RISSOIDAI. 
17. Assiminea paladilhii. 
Omphalotropis Paladilhii, Issel, Ann. Mus, Civ. Genova VI, 1874, Sarawak 
—long. 54, diam. 4 mil.; ? = Hydrocena lirata, Morelet, Rev. Zool, 1862, 
long. 63, diam. 4 mil., banks of the Bien-Hoa, Cochin-China. 
2 Sarawak (typical) ; ex c. Prof. A. Issel. 
18. Assiminea elie. 
Assiminea Eliae, Paladilhe, Ann. Sci. Nat.(VI), Vol. IT, 1875, Rochelle and 
Coimbra, 
20 Bayonne; coll. G. Nevill, Esq. 
A true Assiminea and very like the Chinese A. sinensis. 
19. Assiminea latericea. 
Assiminea latericea, H. & A. Adams, P. Zool. S, 1863, p. 434, Yang-tsze- 
kiang & Peiho, 
1 China (typical) ; ex c. H. Adams, Esq. 
20. Assiminea (?) dubia. 
Cyclostoma dubium, Pfeiffer, Zeits. Mal. 1846, Opara—long. 9, diam. 5 mil. ; 
Jide Pease, 1869, species of Assiminea. 
4 Opara (typical ?); ex c, Dr. H. Dohrn. 
I believe this will prove a species of Omphalotropis, rather 
than of Assiminea. 
1 Japan (?) ; ex Mr. R. Damon. 
Long. 54, diam. 4 mil. Despite the difference in size, it agrees 
exactly with typical figure in the Conch.,-Cab. II. 
21. Assiminea subcornea, u. sp. 
Hydrocena cornea, Pfeiffer, P. Zool. S. 1854, Borneo & Bashee I—long. 
10, diam.5 mil. (not Optediceros corneum, Leith, 1858). 
1 Japan (?); ex Mr. R. Damon (as “4. cornea, Pfr. coll. Rein.”’). 
This looks to me a true Assiminea ; long. 7, diam. 4 mil. 
22. Assiminea (?), sp. 
1 Opara; exc. Dr. H. Dohrn (mixed with Ass. ? dubia). 
Long. 5, diam, 4 mil. Probably a species of Omphalotropis.
