"Lockhartia" cushmani Applin and Jordan and notes on two previously described foraminifera from tertiary rocks in Florida

This paper discusses changes made in the names of three foraminiferal species originally described by the writers, with particular emphasis on "Lockhartia" cushmani Applin and Jordan. The internal characters of this form are fully described and compared with the diagnostic characteristics of the genus Lockhartia Davies and with the geno-lectotype of Rotalia, R. trochidiformis Lamarck, as given by Davies (1932). Comparisons are also made with Lockhartia bermudezi Cole. A plate of illustrations demonstrates the features described. In addition. Elphidium leonensis Applin and Jordan is briefly discussed and the generic placement of Miscellanea nassauensis Applin and Jordan is mentioned.
