Genus PSEUDOPOLYMORPHINA Cushman and Ozawa, 1928 



Psexidopolymorphina Cushman and Ozawa, Contr. Cushman Lab. Foram. Res., 



vol. 4, p. 15, 1928. 

 Synonym: Polymorphina (part) of authors. 



Genoholotype. — Pseudopolymorphina hanzawai Cushman and Ozawa. 



Test elongate, often somewhat compressed; chambers rounded, 

 generally as long as broad, arranged in a closed sigmoid series in the 

 earlier stages, becoming biserial in the adult; sutures distinct, de- 

 pressed; aperture radiate. Jurassic to Recent. 



Recently this genus has been placed as a synonym of Apiopterina 

 Zborzewski. As already noted the latter is not recognizable and is 

 based on a more or less globular form, whereas Pseudopolymorphina 

 is biserial in the adult. 



PSEUDOPOLYMORPHINA cf. SUBNODOSA (Reuss) 



Plate 9, Figures 11a, h 



The small, somewhat immature specimen figured may possibly 

 belong to this species of Reuss, which has been mainly recorded from 

 the Tertiary of Europe. It is from Port Lotten, Kersail, Caroline 

 Islands. 



Genus SIGMOMORPHINA Cushman and Ozawa, 1928 



Sigmomorphina Cushman and Ozawa, Contr. Cushman Lab. Foram. Res., vol. 

 4, p. 17, 1928. 



Genoholotype. — Sigmomorphina yokoyamai Cushman and Ozawa. 



Test, at least in the adult, with the chambers added in planes 

 slightly less than 180° and more than 144° apart from one another, 

 each succeeding chamber farther removed from the base. Eocene to 

 Recent, possibly also in the uppermost Cretaceous. 



This genus will not be confused with Guttulina when forms of the 

 two genera are studied, the later development of Sigmomorphina 

 being very different and being derived from Guttulina by the addition 

 of distinct characters. 



SIGMOMORPHINA SEMITECTA (Reuss) var. TERQUEMIANA (Fornasini) 



Plate 9, Figures 6-9 



There are fairly numerous specimens from off Nairai, Fiji, and from 

 Levuka, Fiji, in 12 fathoms, several of which are here figured and 

 which seem close to this variety. It has not previously been recorded 

 from the Pacific, but has been recorded from the shallow water of 

 the Mediterranean. 



Genus GLANDULINA d'Orbigny, 1826 



Glandulina d'Orbigny, Ann. Sci. Nat., vol. 7, p. 251, 1828. 

 Synonym: Nodosaria (part) of authors.
