ASTARTE obovata. 



TAB. CCCLIll. 



Spec. Char. Obovate, uniformly convex, cor- 

 rugated ; lunette impressed ; anterior margin 

 subtruncated, interior edge crenulated. 



JL HE transverse rugae are most conspicuous upon the 

 anterior part of the surface, where they are also some- 

 what waved. From A. excavata, tab. 233, it may be 

 distinguished by the anterior side not forming a separate 

 lobe, and by being less elongated transversely. 



Found by Prof. Sedgwick in the inclined beds of the 

 ferruginous Sandstone, beneath the green Sand, on the 

 eastern side of Sandown-bay, on the Isle of Wight ; and 

 mentioned by him in his paper on the Geology of the 

 Isle of Wight, in the third Vol. new series of tiie Annals 

 of Philosophy, p. 335, No. 5.
