Plate 7. ORBULINIDAE: ORBULININAE, CATAPSYDRACINAE 



Figures 1-5. Orbulina universa d'Orbigny 35 



1, Three-chambered hypotype (USNM P3911) 

 from the Recent Atlantic, showing rarer multi- 

 locular development, but with typical areal 

 aperture of large scattered pores. 2, Hypotype 

 (USNM P3908), from the Miocene Chocta- 

 whatchee formation of Florida, showing early 

 Globigerina stage incompletely enveloped by later 

 spherical chamber, termed "CandorbuHna" by 

 Jedlitschka. 3, Typical spherical unilocular 

 hypotype (USNM P3910). 4, Rare bilocular 

 form (USNM P3909) of the type described as 

 "Biorbulina" by Blow. Both from the Recent 

 of the Atlantic. 5, Hypotype (USNM P3907), 

 showing "Candorbulina" type of development, 

 from the Miocene of Austria. Figs. 1, 3, 4, X 55. 

 Figs. 2, 5, X 95.

 and Bermudez). 



6a, Spiral side of holotype (Cushman Coll. 

 23430). 6b, Umbilical side, showing umbilical 

 bulla covering primary aperture. 6c, Edge view, 

 showing infralaminal accessory apertures be- 

 neath umbilical bulla. From the Eocene of Cuba. 

 7a, 8a, Spiral side of hypotypes (USNM P4218a, 

 b). 7b, 8b, Umbilical side, showing slight varia- 

 tions in size of bullae. 8c, Edge view, showing 

 infralaminal accessory apertures. From the 

 Oligocene-Miocene Cipero formation of Trinidad, 

 B.W.I. All X 60.

 tendency to spread along sutures, with small in-

 12a, Spiral side of hypotype (USNM P3922). 

 12b, Umbilical side, showing enveloping final 

 chamber obscuring primary aperture and earlier 

 umbilical region. 12c, Edge view, showing 

 Porticulasphaera stage with development of 

 bullae over sutural openings, characteristic of 

 Globigerinatheka. From the Eocene Navet for- 

 mation of Trinidad, B.W.I. X 95.
