Description. — Test cylindrical, the triserial portion short, iiniserial 

 portion also short, composed of three or four, occasionally five cham- 

 bers, transverse section rounded; chambers distinct, rounded, in- 

 ternally partially divided by a network of incomplete divisions, 

 sutures in the uniserial portion indistinct; wall coarsely arenaceous 

 but on the exterior rather smooth and finished; aperture a simple 

 rounded opening in the center of the end wall of the chamber, in 

 some cases with a slight valvular tooth; color reddish-brown. 



Length up to 1.5 mm. 



Distribution.— Type-spQcim.en (U.S.N.M. No. 16869) from Albatross 

 station D2425 in 119 fathoms (205 meters), off Cape Hatteras. 

 Specimens are common at some stations off the coast of Florida and 

 in the Gulf of Mexico. Goes records this species from the Caribbean 

 in 68 to 830 fathoms (125 to 1,510 meters). I failed to find speci- 

 mens in as deep water as this. Flint's records it from D2377 in 210 

 fathoms (384 meters), Gulf of Mexico, from which station I also 

 have abundant specimens. It seems to be a common species at 

 moderate depths and to show very little variation. I have named 

 this species in honor of the late Admiral James M. Flint.
