Genus TELLINIMERA Conrad 

 [Am. Jour. Conch., vol. vi, 1870, p. 173] 



Type. Tcllinimera eborea Conrad. 



" A more perfect hinge of the left valve of this genus gives the following 

 character : Cardinal teeth two ; anterior one V-shaped, nearly direct, or 

 slightly directed anteriorly; the posterior tooth bifid, oblique; posterior 

 lobe thick, and longer than the anterior lobe; cardinal plate compara- 

 tively broad laterally, posteriorly channeled ; anteriorly with a small pit. 

 apparently for the reception of a lateral tooth." Conrad, 1870. 



Conrad took the unwarranted liberty of changing the name Tellinimera 

 to Tellimcra when he elevated the subgenus to the rank of a genus. 



The genus is restricted in its known distribution to the Cretaceous.
