GASTEROPODA. 81 



My cabinet contains but four specimens of tliis species, and those are not in very 

 good condition ; the identification, therefore, must be considered doubtful. The 

 volutions project a little at the lower part, which give them a conoidal form : Mon- 

 tague says, "terminating in a fine point;" my specimens have the apex very obtuse, 

 so have all the species of this genus.

But one specimen of this shell has come into my possession ; it appears to be 

 identical with the recent British species. The costa3 are not quite vertical, but have 

 a little inclination, so that the lower part inclines to the left of a perpendicular line, 

 but they do not curve. Montague states this species to be covered, in a recent 

 state, with a brown epidermis. It is said by Dr. Fleming (British Animals, p. 303) 

 to be a deep-water shell. 



6. Chemnitzia inteenodula. S. Wood, 1847. Tab. X, fig. 6, 6 a. 



Ch. Testa, subulatd, subcglindricd, elongatd ; anfractibus numerosis planis, longitudinaliter 

 costatis ; costis obliquis, obtusis, cunfertis, ad interstitias serie unicd granulorum ; aperturd 

 subquadratd j columella recta uniplicatd ; labro simplici, intus Icevigato. 



Shell tapering or subcylindrical, smooth, and glossy, with twelve or fourteen flat 

 volutions, longitudinally costated ; costse slightly oblique ; interspaces with an 

 elevated nodule ; aperture subquadrate ; columella straight, with one fold ; outer lip 

 simple, smooth within. 



Axis, fy of an inch.

This species is not rare. In some characters it resembles Turbo gracilis, Broc. 

 (Tab. vi, fig. 6), but that shell has the ribs more vertical, and has not the connecting 

 link between them. Our shell appears as if its ribs were bound together by some- 

 thing passing through them, which gives a sort of knob between each rib, with a
