54 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 77 



Test elongate, fusiform, margin almost entire, initial end more or 

 less pointed, apertural end produced into an elongate, cylindrical 

 neck; chambers not numerous, inflated; sutures fairly distinct, but 

 not depressed, except in the case of the last-formed one; wall more or 

 less hispid, the last chamber especially more inflated and spinose 

 and often covered with fistulose tubes; aperture a long neck, not 

 radiate. 



Length, 0.50-0.85 mm.; breadth, 0.22-0.28 mm.; thickness, 

 0.22-0.28 mm. 



The present species is very unique in its long produced neck and 

 lip, which are similar to those of Uvigerina, but the other characters 

 are undoubtedly those of Pyrulina. 



Distribution. — It is known as a Recent species and seems to be 

 mostly hmited to the deep sea. Brady figures an excellent specimen 

 from the South Atlantic from Challenger 388, in 1,990 fathoms 

 (3,640 meters), and records it also from the South Pacific. We have 

 Recent specimens from the Atlantic off the eastern coast of the 

 United States from Albatross D2035 in 1,362 fathoms, D2105 in 

 1,395 fathoms, and D2562 in 1,434 fathoms. There are also speci- 

 mens with hispid exterior from the Tertiary of Trinidad, from South 

 of Hospital Hill, San Fernando, collected by P. W. Jarvis which are 

 very close to Recent specimens. We have also a single smooth speci- 

 men with an elongated neck similar to this species from the middle 

 Oligocene of Hermsdorf near Berlin, which should be noted in con- 

 nection with this species. More specimens are needed to definitely 

 place it. It also occurs in the Pliocene of Fiji, a series of sediments 

 deposited in fairly deep water.
