number, flatly convex, smooth, very finely plicately

Gray, Loudon’s Magazine, New Series, vol. i. p. 487.

It is a character to be observed in this species, that the 
delicate longitudinal ribs are rather distant on the first few 
whorls of the shell, and become gradually finer and closer 
towards the aperture.
