ART. 6 FORAMINIFERA: POLYMORPHINIDAE — -CUSHMAN AND OZAWA 105 



Distribution. — We have a good series of the present species from 

 the upper Ohgocene of Ahnatal, near Cassel, Germany. There is a 

 single specimen in the collection from the Oligocene of Lattdorf, 

 Germany. 



PSEUDOPOLYMORPHINA CURTA Cashman and Ozawa, new species 



Plate 27, figures 3 a, & 



Pseudopolymorphina species Cushman and Ozawa, Jap. Journ. Geol. and 

 Geogr., vol. 6, 1929, p. 71, pi. 15, fig. 7. 



Test oval, compressed, rounded at both ends, margin even; cham- 

 bers few, as long as wide, more or less compressed, slightly embracing, 

 arranged in an almost biserial series; sutures but little depressed, 

 often obscured; wall thin, smooth; aperture radiate. 



Length of holotype 0.55 mm. ; breadth 0.40 mm. ; thickness 0.27 mm. 



Holotype. — (Cushman Coll. No. 11731.) From 32 fathoms, one-half 

 mile northwest of Eagle Island, Casco Bay, Me. 



A characteristic of the species is the oval test composed of a few 

 more or less compressed rounded chambers. Pseudopolymorphina 

 species recorded by us from the upper Pliocene of Sawane, Japan, is 

 very similar to the present species. 



Distribution. — In addition to the above localities, we have speci- 

 mens from Hudson Bay, Richmond Gulf (about 3 miles from entrance, 

 in 15-20 fathoms). 



PSEUDOPOLYMORPHINA SPATULATA (Terquem)

(in text) . 



Test slightly compressed, elongated, periphery broadly rounded; 

 chambers inflated, slightly overlapping, arranged at first in a nearly 

 quinqueloculine or triloculine series especially in the microspheric 

 form, abruptly becoming biserial; sutures but little depressed, distinct; 

 wall smooth; aperture radiate. 



Maximum length 2.30 mm.; breadth 0.55 mm.; thickness 0.30 mm. 



As is noted in the remark given with Pseudopolymorphina decora, 

 it is diflicult to distinguish Pseudopolymorphina spatulata from 

 Pseudopolymorphina decora because of transitional forms. Especially 

 the megalospheric form of the present species, having an almost 

 biserial test, shows a great resemblance to Pseudopolymorphina decora. 



Polymorphina truncata d'Orbigny, figured by Fornasini, having 

 alternating rounded chambers, is not different from the present 

 species, although its apertural view is almost circular.
