; Otinea. 
Mollusea Auriculaeea in rupibus littoralibus degentia, 
structura organorum corporis externorum, nec non dentium 
lingualium Auriculeis et Melampeis congrua. Testa aurifor-

acuto. 
Otininae H. et 4. Adams Gen. rec. Moll. II. p. 249. 
Subfamilia a Claris fratribus Adams proposita, inter 
Auriculacea similem fere locum obtinens, ac Ancylea inter 
Limnaeacea. Unicum hucusque genus notum est huc pertinens: 
|l. Otina Gray. 
Testa sigaretiformis, paucispira, anfractibus rapidissime 
accrescentibus ; apertura ampla, subsymmetrica, margine colu-

Helicis, Velutinae, Galericuli sp. Auctorum. 
Genus a Cl. Gray primum ex typo Helicis otidis Turt. 
tamquam sectio Velutinae indicatum, tum a Cl. Clark cum du- 
bio inter genera Conovulidarum adoptatum, a Cl. Forbes et 
Hanley Pyramidellidis adnumeratum, 1854 a Cl. Gray ex 
dentium formatione ad Awriculidas relatum, tres solummodo 
species notas (quarum unam dubiam) complectitur.
