TURRITELLA cingenda. 
TAB. CCCCXC1 X.—Jig. 3. 
Spec. Char. Subulate, transversely striated ; sides 
of the whorls rather concave,, upon their lower 
edges is a crenated band. 
The upper part of the spire is slightly ribbed, but the 
ribs or waves are gradually lost; the striae are fine and 
impressed, they are closer in the middle of each whorl ; 
the base is flat with a round (and in the young shell, cre- 
nated) edge, which produces the band around the spire. 
Found in shaley Clay in Robinhood’s Bay near Scar- 
borough, by Mr. Bean, who has kindly lent us a number 
of interesting fossils from that neighbourhood.
