LUCINA divaricata. 
TAB. CCCCXVII. 
Spec. Char. Orbicular, gibbose, marked with 
two sets of oblique arched striae, and 3 or 
4 deep lines of growth. 
Syn. Tellina divaricata, Linn. 
Lucina divaricata, Lam. env. de Paris ,

This round and almost globose shell, is rendered very 
remarkable by two sets of hollow lines that converge 
towards each other, and meet upon the disk near the 
posterior side, at an obtuse angle ; the shell is thick and 
glossy, inside it is commonly dull, and partially granu- 
lated. 
So exactly do the fossil specimens agree with recent 
ones from the West Indies, that Lamarck considers 
them the same, and we see no reason to differ from him 
in opinion ; they are both liable to some variation, 
especially in the fineness of the pattern : the recent 
specimens are white. 
This pretty Hor dwell fossil has been sometime in the 
collection : the addition of a very neat individual has 
lately been made by the Rev. T. Cooke. 
It occurs also at Grignon and Bordeaux. 
The large figures are from Bordeaux specimens*
