ACTEON Acutus. 
TAB. CCCCL V.—Jig. 2. 
Spec. Char. Subcylindrical, smooth ; spire 
conical, acute ; one plait upon the columella. 
Generally smaller, and not so perfectly cylindrical as 
the preceding, because the spire is not so much concealed, 
and because it is more tapered towards the base ; the 
aperture occupies about three fourths of the whole 
length. 
Small specimens of this do not at first sight appear 
much related to the A. cuspidatus, they are so much more 
pointed at both ends, but an examination of the columella, 
and form of the aperture, soon point out their connection. 
They occur together at Ancliffe.
