there 1 fine carina intervening, rather inequidistant ; on the upper 

 whorls 4. Spire, well-elevated, with straight outlines. Whorls, 

 4f, scarcely convex, with a very light suture. Aperture, larger than 

 semicircular, rather flattened above, moderately expanded, much on 

 the right below. Labrum, slightly double and very little pectinated 

 by the carinse, produced above and much reflected, scarcely detached 

 from body-whorl. Labium, little detached from body-whorl, straight, 

 except the curve to the right below ; very little below the plane 

 of labrum in the lower part. Umbilicus, moderately deep. Labral 

 lamella, very little produced. Operculum, concave, minutely gra- 

 nulated. 



Height 0-077, greatest breadth 01 1, least breadth 0*078. . 



Named in compliment to M. Felipe Poey, now of the Havanna. 



Lindsleya Henryana, Chitty. 



Hab. Pool's Rock and Halley's Mountain, Hanover. 



Form, globose-conic. Colour, pale horn. Sculpture, 18 blunt 

 coarse spiral carinse, with 1 very fine (about the periphery) inter- 

 vening ; on the upper whorls 7. Spire, well-elevated, with straight 

 outlines. Whorls, 4\, well-rounded, with deep suture. Aperture, 

 very slightly expanded, more than a semicircle, spreading above and 

 below, very slightly detached from the body-whorl. Labrum, thin 

 and smooth, pectinated by about 10 points outwards, scarcely pro- 

 duced above. Labium, moderately detached from body-whorl, thin, 

 curved to the right below, on a plane with the labrum above, rather 

 lower below. Umbilicus, rather broad, and suddenly very deep. 

 Labral lamella, considerably produced, more expanded above ; within 

 the umbilicus, and higher up the outside of the labium is another 

 lamella, almost as strong as the labral lamella. Operculum, slightly, 

 concave, with about 1 2 very coarse granulations on the labral lower 

 side. 



Height 0-053, greatest breadth 0-067, least breadth 0-054. 



Named in compliment to Henry Adams, Esq., of London, the

Lindsleya Alderiana, Chitty. 



Hab. John Crow Hill, Portland. 



Form, globose-conic. Colour, pale yellowish horn. Sculpture, 

 striee of growth visible ; 1 7 strong spiral carinse, with 1 fine in each 

 interspace, 3 fine intervening at the periphery, where the strong 

 carinse are wide apart ; on the upper whorls 3, with finer intervening. 

 Spire, well -elevated, with slightly concave outlines. Whorls, nearly 

 5, moderately convex, with a moderate suture. Aperture, semicir- 

 cular, slightly expanded below. Labrum, slightly produced above, 

 rather reflected, scarcely detached from the penult whorl, rather 

 strongly pectinated by about 1 1 of the spiral carinse. Labium, very 

 slightly curved to the right, else almost straight, moderately de- 

 tached from the body-whorl, rather below the plane of the labrum. 

 Umbilicus, very deep. Labral lamella, slightly produced. Oper-
