TEREBRATULA Fimbria. 



TAB. CCCXXVI. 



Spec. Char. Orbicular, gibbose ; margin iin- 

 dulato-plicated. 



Full grown shells of this sptcies are more orbicular 

 than young ones, which are rather quadrangular, and 

 not so gibbose : the plaited margin or frill occupies 

 about a fifth part of the diameter of the shell, and is 

 partially separated from the remaining smooth part by a 

 sudden elevation. 



Found in fine grained Limestone, at Charlton Kings, 

 in Glostershire, and at Cleeve Hill, near Cheltenham ; 

 from the former locality it was sent me by Mr. Richard 

 Taylor, and from the latter by Miss E. Warne.
