ART. 6 FORAMINIFERA: POLYMORPHINIDAB— CtrSHMANANDOZAWA 91 



Distribution. — This species is apparently confined to the cold water 

 of the American side of the Atlantic, very abundant off the New 

 England coast. Our specimens are from the following localities: 

 Bay on east coast (south of Black Whale Harbor, Hudson Bay), 

 10 fathom_s; Gaspe Bay, 10-40 fathoms; Cobscook Bay; off Trials 

 Island, Eastport, Me.; between Crotch and Stave Islands, Casco 

 Bay, Me., 7 fathoms; shore sand, Coffins Beach, Annisquam, Mass.; 

 beach sand, Newport, K. I.; one broken specimen, which may be this 

 species, is from off Iceland. It occurs also at Albatross stations in 

 cold water off the New England coast. 



PSEUDOPOLYMORPKINA SUBOBLONGA Cushamn and Ozawa, new species 



Plate 23, figures 3 a-c 



Test elongated, the greatest breadth in the upper half, obtuse at 

 the base, acute at the apertural end; chambers twice as long as wide, 

 inflated, slightly overlapping, arranged at first in a quinqueloculine 

 series, later becoming biserial; sutures depressed, distinct; wall 

 smooth, rather thick; aperture radiate. 



Length 0.90-1.30 mm..; breadth 0.35-0.60 mm.; thickness 0.20- 

 0.35 mm. 



Holotype. — (Cushman Coll. No. 11663.) From upper Pliocene, 

 Okuwa, Province of Kaga, Japan. Paratypes in collection of Geologi- 

 cal Institute, Imperial University of Tokyo, Japan. 



The present species represents an intermediate form between 

 Quttulina and Pseudopolymorphina, and the arrangement of chambers 

 is not very definite, but generally begins with a quinqueloculine 

 series which becomes more or less biserial later. It differs from 

 Pseudopolymorphina ligua, of the European Tertiary in its less regular 

 biserial arrangement of rather short chambers and depressed sutures. 



Distribution. — It occurs as an upper Pliocene fossil in Japan and as a 

 living species off the coast. We have specimens from the following 

 localities : 



Recent. — Albatross D4807, off Cape Tsiuka, Japan, 44 fathoms. 



Upper Pliocene. — Okuwa. Province of Kaga, and Natsukawa, 

 Province of Echigo, Japan.

Plate 23, figures 4 a, & 



Variety differing from the typical form in its surface ornamenta- 

 tion, consisting of a few low longitudinal costae running from the 

 initial end, obscured near the aperture. 



Length of holotype 1.05 mm.; breadth 0.30 mm.; thickness 0.25 

 mm.
