TURRITELLA cingenda. 



TAB. CCCCXCIX— Jig. 3. 



Spec. Char. Subulate, transversely striated ; sides 

 of the whorls rather concave, upon their lower 

 edges is a crenated band. 



1 HE 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.
