/l. lineatus. Plate 4. Fig. 97. 
Description. Shell conical, transversely furrowed ; fur- 
rows closely set with minute punctures ; substance of the 
shell thin; spire elevated, pointed; suture impressed ; colu- 
mella with one fold; whorls six; mouth rather narrow, 
about half the length of the shell ; outer lip crenate. 
Length .3, Breadth 3-20ths, of an inch. 
Observations. 'This very beautiful and interesting little 
species closely resembles the last described, but is spe- 
cifically different. It has a still closer resemblance to a 
species in my cabinet from the Paris basin, which I do not 
know to be described. It is not, however, quite so elevated 
as that specimen. It differs, also, in having one band or 
space, without a furrow, on the superior part of the body 
whorl, while the other has two such bands. In our spe- 
cies the supérior whorls have but three furrows, that from 
Paris has four. These characters may be found to differ in 
other individuals. In outline it resembles the striatus 
(Sowerby) (Min. Conch. vol. 5), but differs in many other 
characters. The Acteon ovoides (Conrad), from the Ter- 
tiary of Maryland, is very similar to this in general form, 
but does not appear to have any punctures in the furrows. 
I have not, however, seen a good specimen of it.
