NEW ARCTIC FORAMINIFERA COLLECTED BY 



CAPT. R. A. BARTLETT FROM FOX BASIN 



AND OFF THE NORTHEAST COAST 



OF GREENLAND 



By JOSEPH A. CUSHMAN 



('With Two Plates) 



During the course of his expeditions to the Arctic and sub-Arctic 

 regions in the past seven years, 1925-1932, Capt. Robert A. Bartlett has 

 obtained, in addition to other extensive collections of marine inverte- 

 brates, considerable numbers of bottom samples which have been ex- 

 amined for foraminifera. A paper has been completed containing 46 

 genera and nearly 100 species of foraminifera from the collections 

 from off the northeast coast of Greenland and from Fox Basin, Baffin 

 Land. Ten of these forms that are apparently new are here described 

 and figured so that they may be available while awaiting publication 

 of the larger paper which will carry full station data for these species. 



Genus URNULA Wiesner, 1931 



Uniitia Wiesner, Deutsche Siidpolar Exped., vol. 20, Zool., p. 82, 193 1. 



Genotype. — Urnula quadrupla Wiesner. 



Test attached, in young stage similar to Webbinella, later adding 

 chambers and each becoming polygonal in outline, whole test plano- 

 convex, rounded, base with a thin chitinous layer, dorsal side with a 

 fine arenaceous covering ; aperture in adults rounded, one near the 

 middle of each chamber. Recent, Arctic and Antarctic. 



This genus has been recently described by Wiesner from material 

 collected in the Antarctic. Another species probably belonging to this 

 genus was also collected in the Antarctic and should be known as 

 Urnula depressa (Heron- Allen and Ear land) . The present new species 

 extends the range of this genus to the Arctic. 



URNULA ARCTICA, n. sp. 



Plate I, figs. I, 2 



Test attached, plano-convex, dorsal side somewhat rounded and 

 convex, ventral side conforming to the surface of attachment ; cham- 

 bers four to eight in number, rather uniformly arranged, those tests 

 having four chambers with the whole test in a circle divided by sutures
