Helix carinata, Min. Conch, t. 10. 
Having ascertained by more perfect specimens that the 
Helix carinata , Min. Conch., and Pleurotoma jlammi- 
gera of Phillips are the same species, I have taken the 
opportunity, while figuring some others of the same genus, 
to give another representation of that shell : the former 
figure did not show the zigzag marks of colour which are so 
remarkably preserved, nor the form of the aperture, which 
is probably the reason why Prof. Phillips did not think his 
P.jlammigera to be the same. The outline at the back 
shows the size it sometimes attains. 
De Koninck, in his work on the fossils of Belgium, has 
figured it with its coloured marks, and Gold fuss (tab. 183. 
f.9.) has given the same shell, but neither of these authors 
has yet published the name. 
PLEUROTOMARIA conica. 
TAB. DCXL .—fig. 4. 
Spec. Char. Conical, with straight sides and pro- 
minent convex base; whorls flat above, con- 
vex below the band, transversely and elegantly 
striated ; striae above the band very oblique, 
arched ; band concave, prominent, with a 
furrow beneath it; umbilicus closed, with a 
thin columella.
