 39, 40 (in text); Bull. 100, XJ. S. Nat. Mus., vol. 4, 1921, p. 112, pi. 23, fig. 5. 



Description. — Test elongate, rounded in end view, composed of 

 inflated chambers separated by rather deep sutm^es, making the 

 outline of the test sinuous; wall somewhat coarsely arenaceous; 

 aperture in the early chambers slit-like at the ventral border of the 

 inner margin, in later chambers gradually moving away from the 

 margin and in the last-formed chamber subterminal and rounded. 



Length about 1 mm. ; microspheric proloculum 0.022 mm. 



Distribution. — There are single specimens from three stations 

 southeast of New York which are very close, if not identical, with 

 this species which I have described from the western Pacific in 

 fairly deep water. They are perhaps less rounded than the Pacific 

 form, but have the characteristic aperture which stands out, with a 

 tubular neck some distance above the base of the chamber. There 

 is another specimen which questionably may be this, from off Fowey 

 Rocks, Florida, in 70 fathoms (128 meters).
