Description. — Test stout, somewhat elongate, tapering slightly 

 until near the initial end where it tapers abruptly to the somewhat 

 blunt end; triserial portion nearly circular in cross section, of few 

 chambers, the later biserial portion making up about three-fourths 

 of the test, slightly compressed; chambers overlapping and appear- 

 ing crowded, broadly elliptical in cross section, inflated; suture 

 deep and distinct, end strongly convex, wall of fine arenaceous 

 or calcareous shell material, smooth; aperture oval, slightly back 

 from the inner margin of the chamber and with the border raised 

 somewhat and thickened; color light gray. 



Length 0.38-1.00 mm. 



Distribution. — This recent species is very widely distributed, 

 being one of the few Textulariidae associated with typical Glohi- 

 gerina-ooze. It is very widely distributed all over the world and 

 shows little if any variation. It has proved to be one of the most 

 common species of the genus in the material I have examined from 

 the western Atlantic, being found abundantly off the entire eastern 

 coast of the United States, in the Gulf of Mexico, and in the Carib- 

 bean Sea. Challenger stations show it is distributed generally over 

 both the South and North Atlantic.
