CATALOGUE 



OF THE KNOWN" SPECIES, RECENT AND FOSSIL, 



OF THE 



FAMILY MARGINELLID^. 



BY JOHN H. REDFIELD. 



The Marginellidce form a distinct and well marked group, and may be 

 regarded as a subdivision of the larger group of Volidacece, and inter- 

 mediate between Volutidce and Cyprceidce. As now restricted, the family 

 contains only the genera Erato, Marginella and the fossil genus Vol- 

 varia, including in Marginella many subgenera proposed by authors. 

 The genus Ringicula, of Deshayes, which some have placed next to Mar- 

 ginella, is now better referred to the family Tortiatellidce, near Cinulia, of 

 Gray. The genus Packyhathron, of Uaskoin, represented by two little 

 known species, and by him placed in the family Marginellidce, is probably 

 more nearly related to Oniscia, and by Cheuu has been with good judg- 

 ment referred to the family Gassididce.
