CATALOGUE 



OF THE KNOWN SPECIES, RECENT AND FOSSIL, 



OP THE 



FAMILY MARGINELLID^. 



BY JOHN H. REDFIELD. 



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

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

 mediate between VohUidce 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 Tornatellidce, near Cinulia, of 

 Gray. The genus Pachybathron, of Gaskoin, represented by two little 

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

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

 ment referred to the family Gassididce.
