CYPRINA. j.i3 



G. angtdafa of Briart and Cornet appears to be closely related to C. aineaia, 

 Sowerby (see p. 134). 



0. {Venilicardia) Jid-eni, dc Loriol,' from the Gault of Cosne, resembles some 

 forms of G. angulata.- 



Beviarl-s. — G. aiK/ulafa varies in its relative height and length, and in I lie 

 position of the umbones. The shell is usually stont, Init occasionally rathcf lliin. 

 Sowerby gives a good figure of G. angnlata, except (liat the teeth, as pointed out 

 by Rtoliczka, are not correctly drawn."
