 Parr. 



Holotype of Globoquadrina altispira (Cushman and 

 Jarvis) (Cushman Coll. 22482) from the Miocene Bow- 

 den marl at milestone 71 east of Port Antonio, Jamaica, 

 B. W. I. 



Figured specimen of Globoquadrina sp. (USNM 

 P4575) from the Oloborotalia mayeri zone of the Miocene 

 Lengua formation, on Cunjal road, between Barackpore 

 and Princes Town, Trinidad, B. W. I.

Genus Hastigerinella Cushman, 1927 



Plate 5, Figures l-3b 



Hastigerinella Cushman, Contr. Cushman Lab. Foram. Res., 

 vol. 3, p. 87, 1927. 



Type species: Hastigerina digitata Rhumbler, 1911 

 [=Hastigerinella rhumbleri Galloway, 1933]. Fixed by 

 original designation and monotypy. 



Test free, trochospiral, early portion with globular 

 chambers, later chambers radially elongate, clavate or 

 cylindrical; sutures distinct, depressed, radial; wall 

 calcareous, perforate, radial in structure, with elongate 

 spines which may be concentrated at the outer ends of 

 the chambers, but are normally broken away in fossil or 

 dead shells; aperture interiomarginal, extrairnibUical- 

 umbilical, a broad arch which becomes more extensive 

 with age, extending to the periphery or even becoming 

 spiro umbilical. 



Remarks: Hastigerinella differs from Hastigerina in 

 being trochospiral instead of planispiral, and in having 

 elongate chambers. It differs from Hastigerinoides 

 Bronnimann in being distinctly trochospiral rather than 

 planispiral. 



Cushman, in describing Hastigerinella (1927, p. 87), 

 cited as type species "Hastigerina digitata Rhumbler, 

 Foram. Plankton Exped., Part 1, 1911, pi. 37, fig. 

 9a,b." The digitata of Rhumbler, 1911, is not con- 

 specific with Globigerina digitata Brady, 1879, which is 

 another species of Hastigerinella. This led Galloway 

 (1933, p. 333) to cite as type Hastigerinella rhumbleri 

 n. sp. This confusion primarily results from Rhum- 

 bler's failure to give any descriptions for his plates in 

 the "Plankton-Expedition" volume cited above. How- 

 ever, Ellis and Messina (1949, p. 40) published the 

 plate explanations of Rhumbler's "Plankton-Expedi- 

 tion" that they had obtained as a manuscript from Dr. 

 Otto Wetzel. The copy furnished by Dr. Wetzel was 

 from the manuscript preserved in the library of the 

 University of Gottingen, Germany. On the plate 

 explanation for plate 37, figs. 9a,b were stated to be 

 Hastigerina digitata (Brady) variante digitifera. This 

 "variante" is thus the use of a new name, but it is 

 invalid, according to the Rules of Nomenclature (Art. 

 25c), as no description was given. It must be assumed 

 that Cushman considered the combination Hastigerina 

 digitata as used by Rhumbler (1911, pp. 202, 220) as 

 being a new combination and not referring to Globi- 

 gerina digitata Brady, 1879, for nowhere did Rhumbler 



(1911) use the name Brady in combination with Hasti- 

 gerina digitata. The type thus should be cited as 

 Hastigerina digitata Rhumbler, 1911, but this is a 

 homonyn of H. digitata (Brady), 1879. Galloway in 

 reality only renamed this homonyn and did not describe 

 a new species as he stated, hence the name Hastigerin- 

 ella rhumbleri Galloway, 1933, is the vahd name for the 

 species. 



Types and occurrence: The original specimens 

 figured by Rhumbler were from the Atlantic Ocean in 

 2,000 meters. Figured hypotype of Hastigerinella 

 digitata (Brady) (USNM P3037) is from Challenger 

 Station 120, lat. 8° 37' S., long. 34° 28' W., at 675 

 fathoms. 



Range: Miocene to Recent. 



Genus Globigerinoides Cushman, 1927 



Plate 4, Figubes 2a-c 



Globigerinoides Cushman, Contr. Cushnaan Lab. Foram. Res., 

 vol. 3, p. 87, 1927. 



Type species: Globigerina rubra d'Orbigny, 1839. 

 Fixed by original designation and monotypy. 



Test free, trochospiral; chambers globular to ovate; 

 sutures depressed, radial; wall calcareous, perforate, 

 radial in structure, surface smooth, hispid or spinose; 

 primary aperture interiomarginal, umbilical, with 

 previous apertures remaining open into the umbilicus, 

 smaller secondary sutural apertures on the spiral side, 

 one or more per chamber, often confined to the last few 

 chambers. 



Remarks : The type species has a distinctive colora- 

 tion, being rose-colored in the early portion, later 

 chambers progressively lighter, and final chamber nearly 

 white. D'Orbigny originally described the species as 

 having two supplementary apertures on the final 

 chamber and one on the preceding, but added that the 

 number was variable in other specimens. In the speci- 

 men here figm-ed there are two secondary apertures on 

 the spiral side of each chamber of the final whorl, 

 although the specimen must be rotated to see aU of 

 them. 



Globigerinoides differs from Globigerina d'Orbigny in 

 possessing the secondary sutural apertures on the spiral 

 side. 



Types and occurrence: The original types of 

 Globigerina rubra d'Orbigny are in the Musuem National 

 d'Histoire NatureUe, Paris. Figured hypotype of 

 Globigerinoides rubra (d'Orbigny) (USNM P3916) from 

 the Recent, Albatross Station H 47, lat. 17° 46' 30" N., 

 long. 65° 10' 25" W., at 1,482 fathoms. 



Range : Paleocene to Recent.
