The specimens on which the species described herein are based 

 have been in the senior author's hands for several years, some of 

 them since 1920. Suites to serve as cotypes had been selected, some 

 photographs for illustrating the species were taken, and, except for 

 Operculinoides anfiguensis, manuscript names were applied to them, 

 but the descriptions were not written. The final preparation of this 

 paper for publication was done jointly. Seven new species are 

 herein described, as follows : 



OpercuUna tuberculatta: Upper Eocene, Tantoyuca formation, Tampico Embay- 



nieut, Mexico. 

 ■Operculinoides advenus: Upper Eocene, equivalent of Tantoyuca formation, 



Tampico Embayment, Mexico. 

 Operculinoides vicJcsburgensis : Oligocene, Byram calcareous marl of Mississippi 



and Alabama. 

 Operculinoides semmesi: Oligocene, Mes6n formation, Tampico Embayment, 



Mexico.
