Description. — Test suboylindrical, gradually tapering to the initial 

 end, the early triserial portion forming but a small part of the test, 

 the later biserial portion making up fully three-fourths; chambers 

 of the later portion well rounded, nearly circular in cross section; 

 sutures well marked, wall arenaceous, usually rather coarse, but in 

 some cases finer and more smoothly finished; aperture in the biserial 

 portion a subcircular opening near, but not connecting with the 

 inner border of the chamber; color gray. 



Length 1-5 mm. 



Distrihutioti. — This species described in an earlier paper on the 

 Pacific foraminifera occurs also in the Atlantic. Flint had this from 

 ojff the coast of South America, off Brazil, from the region south of 

 Yucatan, off the Windward Islands, in the Gulf of Mexico, and off the 

 coast of Georgia. Except that I have not had it from off the coast 

 of Brazil, I have had it from all the other regions from which Flint 

 records it. It is interesting also to note that Brady records G. suh- 

 rotundata from Challenger stations 23 and 24 off the Lesser Antilles, 

 close to the stations from which Flint and I have had this species. 

 The distribution of G. flintii in the Atlantic then follows very defi- 

 nitely the distribution of so many species found in the Atlantic, south- 

 ward from Cape Hatteras, in the Gulf of Mexico and the Caribbean 

 and on the eastern coast of Brazil.
