Locality: Figured hypotypes (USNM P5669a, b) 

 from the type section of the Globorotalia fohsi lobata 

 zone, sample JS 32 (TTOC 193786).

 the Globorotalia fohsi robusta zone, sample JS 46

Globorotalia obesa Bolli, new species 

 Plate 29, Figures 2a-3 



Shape of test very low trochospiral ; equatorial pe- 

 riphery strongly lobate; axial periphery rounded. 

 Wall calcareous, perforate, surface finely pitted, in 

 well preserved specimens with fine, short spines. 

 Chambers strongly inflated, spherical; 10-12, arranged 

 in 2-2K whorls; the 4-4}^ chambers of the last whorl 

 increase rapidly in size. Sutiu-es on spiral side radial, 

 strongly depressed; on umbOical side radial, strongly 

 depressed. UmbUicus fairly wide, deep. Aperture a 

 medium to high arch without lip or rim; interiomar- 

 ginal, umbilical-extraumbilical. Coiling random. 

 Largest diameter of holotype 0.5 mm. 



Stratigraphic range (in Cipero and Lengua for- 

 mations): Catapsydrax dissimilis zone to Globorotalia 

 menardii zone. 



Locality: Holotype (USNM P5673) from the type 

 section of the Globorotalia fohsi robusta zone, Cipero 

 type section, Trinidad, sample JS 16 (TTOC 193261); 

 figured paratype (USNM P5674) from the type locahty 

 of the Globorotalia fohsi fohsi zone, sample Bo 185 

 (TTOC 153997). 



Remarks: Globorotalia obesa, new species, dijffers 

 from G. mayeri Cushman and Ellisor in having fewer 

 and more inJBated chambers in the last whorl. 



Globorotalia minutissima Bolli, new species 



Plate 29, Figures la-c 



Shape of test very low trochospiral; equatorial pe- 

 riphery lobate; axial periphery rounded. Wall cal- 

 careous, very finely perforate, surface smooth. Cham- 

 bers ovate; 10-12, arranged in about 2 whorls; the 5 

 chambers of the last whorl increase moderately in size. 

 Sutures on spiral side radial to slightly curved, de- 

 pressed ; on umbilical side radial, depressed. Umbilicus 

 small, shallow. Aperture a narrow slit, often with a 

 lip or rim; interiomarginal, umbilical-extraumbilical. 

 Coiling random. Largest diameter of holotype 0.2 mm. 



Stratigraphic range (in Cipero and Lengua 

 formations) : Catapsydrax stainforthi zone to Globorotalia 

 menardii zone. 



Locality: Holotype (USNM P5775) from the type 

 locality of the Globorotalia fohsi fohsi zone, sample 

 Bo 185 (TTOC 153997). 



Remarks: Globorotalia minutissima, new species, is 

 distinguished from other Globorotalia species of similar 

 shape (e. g., G. mayeri Cushman and Ellisor, and 

 G. obesa, new species) by its very small size and smooth 

 surface. 



Globorotalia archeomenardii Bolli, new species

 periphery slightly lobate; axial periphery acute with a
