 Cuvier constituted thifc genus, having discovered that 

 the organization of the animal differed from those with 

 which it had previously been classed. Bruguiere and 

 La Marck had joined these shells with the Lucinae, 

 but the, latter has now followed Cuvier in separating 

 them. Shell transverse, equivalve, no flexuosity ; api- 

 ces curved inward, opposed to each other; two pri- 

 mary and two lateral teeth, the posterior one nearest 

 to the hinge ; muscular impressions simple, valves some- 

 times convex, strongly ribbed transversely, longitu- 

 dinally striated, margins serrated, and closely inter- 

 locking.
