Notes on Species of Corbiculadm. 



Id 



The Corbicula Largillierti is rare. The specimens in my 

 cabinet, which served for the above description and figure, came 

 from Monsieur Largilliert, from whose collection Philippi 

 described the original Cyrena Largillierti.

 with chestnut or violet on the margins and teeth. The epider- 

 mis is yellowish-green, with occasional spots of a darker color. 

 The hinge is curved and somewhat narrow.
