ART. 6 FORAMINIFERA: POLYMORPHINIDAE — CUSHMAN AND OZAWA 95 



Flint's Polymorphina compressa, described in 1897, is quite different 

 from d'Orbigny's species, figured in 1846, from the Vienna Basin in 

 its broader test and depressed sutures, and its earlier chambers are 

 more rounded and inflated and the sutures are generally much 

 oblique. Our specimens examined are those described by Flint, 



Distribution. — Only known off the Atlantic coast of the United 

 States, 88-440 fathoms. Doctor Flint selected a set of specimens 

 from several stations along the Atlantic coast, but did not keep 

 separate those from the different stations, and so the exact station 

 can not be given. 



PSEUDOPOLYMOEPHINA PHALKROPEI Cushman and Ozawa, new species 



Plate 24, figures S a, b 



Test oblong, but little compressed, rounded at the base; periphery 

 broadly rounded; chambers inflated, as long as wide, slightly em- 

 bracing, arranged in a nearly biserial series; sutures depressed, very 

 distinct; wall thin, smooth, transparent; aperture radiate. 



Length 0.70 mm.; breadth 0.42 mm.; thickness 0.30 mm. 



Eolotype. — (Cushman Coll. No. 2237.) From the Atlantic coast 

 of Massachusetts in the Woods Hole region, dredged by the United 

 States fisheries steamer Phalerope. 



Its round and inflated chambers separated by the deep sutures are 

 the most important character of the species, and there is no other 

 species of the genus which is likely to be confused with the present 

 one. 



PSEUDOPOLYMORPHINA PARVA (Clodius)

Polymorphina {Guttulina) parva Clodius, Archiv. Ver. Fremde Nat. 

 Mecklenburg, 75 Jahrg, 1922, p. 127, pi. 1, fig. 10 a, h. 



Test elongate, subfusiform, more or less compressed; chambers 

 spherical, arranged in a quinqueloculine series, becoming biserial 

 later; sutures much depressed, distinct; wall smooth, thick; aperture 

 radiate. 



Pseudopolymorphina parva is unique in its spherical chambers 

 separated by very deep sutures. 



We have no specimen of the present species,
