PROTEONINA TESTACEA (Flint). 



Plate 20, figs. 1-4. 



Reophax dijjlugifwmis H. B. Bkady, var. testucea Flint, Rep. U. S. Nat. Mus., 



1897 (1899), p. 273, pi. 16, fig. 1. 

 Proteonina difflitgiformis-testacea Rhimbler, Arch. Prot., aoI. 3, ]903, p. 247, 



fig. 81 (in text). 



Description. — Test irregularly flask shaped, apertural end produced; 

 wall composed of a single layer of empty tests of other foraminif era; 

 interior rather neatly finished, exterior more or less irregular. 



Length, up to 2 nmi. 



Distribution. — ^The type station for this species is Albatross D2234, 

 in 810 fathoms, southward of Long Island. I have had material 

 from this same station and from more than 20 stations from Georges 

 Banks to Cape Hatteras, the Gulf of Mexico, and the Caribbean Sea. 



It seems worthy of specific rank for it has very definite and constant 



charactei's.
