and scattered its seeds along the shore ; from wliich arose the 

 apple-trees of Xormandy^ whose brilhant fruit perpetuates 

 the memory of her triumphs and revenge. 



The genus 8olen inckides only such species as have 

 narrow linear shells, with the umboes at one end, and are 

 commonly called Eazor-shells. 



The genus Solecurtus comprises certain natural and 

 characteristic species, that cannot be referred either to the 

 genus Solen, or to any of his relatives. The shell is 

 equivalve, ovately oblong, transverse, gaping at both ends, 

 and covered ofttimes externally with fine undulated stride, 

 crossing the valves obliquely and longitudinally. Two 

 cardinal teeth pertain to each valve ; and one, rarely two, 

 to the other, but not interlocking as in the Solenes. 



The shell of Fanop^eaj which is of a large size, is closely 

 allied to that of Solecurtus. Oval, equivalve, inequilateral, 

 and gaping widely at both ends, it contains a single acute 

 cardinal tooth in each valve, with an external hgament 

 attached to a large fulcrum, and having the muscular 

 points of attachment distant from each other, as also a

The Gli/cimeris presents the characteristic of its tribe, 

 in gaping at both ends. It is equivalve, thick, transverse,
