TROPICAL PACIFIC FORAMINIFERA OF "ALBATROSS" 49 



a higher apertural face and 5 or 5 l / 2 chambers per final whorl. Although 

 compressed in shape, its periphery is rounded and not angled as in 

 P. salisburyi R. E. and K. C. Stewart and some other species. 



Genus SPHAEROIDINA d'Orbigny, 1826 



SPHAEROIDINA BULLOIDES d'Orbigny

Sphaeroidina bulloides d'Orbigny. — Cushman and Todd, 1949, Contr. Cushman 

 Lab. Foram. Res., vol. 25, p. 13, pi. 3, figs. 8-11. 



This probably long-ranging species occurs rarely in a few of the 

 deep-water samples. 



Its wall is thin and translucent and the aperture, when unbroken, 

 is a small semicircular opening filled by a tooth. 



SPHAEROIDINA COMPACTA Cushman and Todd 



Sphaeroidina compacta Cushman and Todd, 1949, Contr. Cushman Lab. Foram. 

 Res., vol. 25, p. 19, pi. 4, fig. 14.— Parker, 1954, Bull. Mus. Comp. Zool., 

 vol. Ill, no. 10, p. 539, pi. 11, fig. 19. 



This species, described and subsequently recorded from the Gulf 

 of Mexico, has also been found around the Marshalls (Cushman, 

 Todd, and Post, 1954, p. 367). A few typical specimens were found 

 in three samples in the present collections. 



This is a larger, more robust species than Sphaeroidina bulloides, 

 with a thicker and nearly opaque wall. The aperture is large, widely 

 open, with incurved edges and only a slight tooth, if any. The area 

 around the aperture is roughened slightly by a granular deposit on 

 the wall. 



Family ANOMALINIDAE 



Genus ANOMALINA d'Orbigny, 1826 



There has been little consistency in the concept of this genus as it 

 has been recognized in the past. Its type species, Anomalina punc- 

 tulata d'Orbigny, described from Recent material from off Mauritius, 

 needs to be understood. Until the characteristics of this species are 

 known, the genus will probably remain, as it has been, a dumping- 

 ground for species whose overall characteristics are similar to those 

 of Cibicides, differing only in being nearly involute on the dorsal side 

 as well as on the ventral. 



The species here placed under this genus are done so on the basis 

 of past usage, but with reservations, pending the clearing up of the 

 problem.
