ASTARTE lineata. 
TAB. CLXXIX.—Fig. 1. 
Spec. Cuar. Obovate, transvere, depressed, 
slightly truncated ; with a few concentric acute 
ridges, and many minute intervening strie 
upon the surface ; lunette lanceolate, small ; 
margin entire. 
eS 
Auwnosrt lenticular; the anterior side is smallest and 
truncated : the slope upon which the cartilage lies is long 
and straight ; the shell is thin, about an inch wide, and 
has nearly thirty prominent sharp lines or ridges. 
It is with some hesitation that I give this as an Astarte, 
not having seen the hinge teeth it is probable that it will 
prove to bea Lucina. The only specimen known is filled 
with granular iron pyrites, and so liable to decompose, 
that I would not risk losing the opportunity of figuring it 
granted me by the Rey. Mr. Buckland : it was found in 
the selenite bed, in the Heddington Clay, near Oxford.
