Relationships within the Tonnacea are discussed briejly; the Oocorythidae are
confirmed at fiill family status. Oocorys umbilicata and 0. bartschi clericus are
described as new. The gross anatomy ofO. umbilicata is described. Oocorys bart-
schi bartschi is now known fi^om throughout the Gulf of Mexico and noHheast
Florida, and the range of 0. caribbaea is extended from south of Cuba to the
Bahamas. Hadroocorys, new genu^, is proposed for 0. verrilli and 0. tosaensis.
The deep waters of the Gulf of Mexico, Carib-
bean Sea and Bahama Islands have been well
sampled by the Bureau of Commercial Fisheries
(now National Marine Fisheries Service) and the
University of Miami. Among the molluscan
specimens obtained, the genus Oocorys Fischer,
1883, is well represented. Notable among these
collections are those from the Tongue of the
Ocean (TOTO), Bahamas, in which three species
(two new) are represented, two in surprising
numbers. This allows more extensive examina-
tion and assessment of intraspecific variations
and suprageneric relationships of Oocorys than
was possible when Turner (1948) published her
monograph of the group.
Collections on which this report is based are
housed primarily in the U.S. National Museum
of Natural History, Washington, D.C., and the
Rosenstiel School of Marine and Atmospheric
Science, University of Miami. Institutional ab-
