Description. — Test elongate, tapering gradually to the somewhat 

 acute initial end; early portion composed of triserially arranged 

 chambers with rounded angles and forming the lesser portion of the 

 test; later portion biserial, often somewhat irregular, wall arena- 

 ceous, of fine material and smoothly finished; aperture elongate, 

 somewhat back from the inner margin of the chamber and often 

 with a raised border; color, gray. 



Length up to 3 mm. 



Distribution.— Type-specimen (U.S.N.M. No. 16710) from Alba- 

 tross station D2105, 1,395 fathoms (2,542 meters). This species 

 described by Schwager from Kar Nicobar was recorded by Brady 

 from seven stations in the North Atlantic at depths of 290 to 1,750 

 fathoms (530 to 3,200 meters), and one in the South Atlantic in 

 1,900 fathoms (3,475). Additional stations were two from the 

 South Pacific and one in the North Pacific. In my material from 

 the North Pacific I failed to find this species and the only other 

 Pacific record is that of Sidebottom quoted above. As it does not 

 occur in any of Chapman's records from the Australian or general 

 Indo-Pacific region, it certainly seems as though its distribution 

 in the South Pacific is either very limited or the recorded specimens 

 may not be typical of this species. 



In the North Atlantic, except for the Challenger stations and the 

 single record of Pearcey from the Faroe Channel it is not recorded. 

 Heron-Allen and Earland fail to record it in their various papers on 

 the foraminifera in the region of the British Isles, The three Chal- 

 lenger stations, for which definite references are given in the North 

 Atlantic are in a line southeast from the region of New York. All 

 but one of the twenty stations from which I have had this species 

 are in this same general region as are also two of Flint's stations. 

 Its concentration of records in this particular area seem to indicate 

 that we have here a variety very limited in its distribution. A 

 comparison of the figures given by Schwager and those of Brady and 

 Flint also seem to indicate that this is not identical with the species 

 described by Schwager. Schwager's measurements, eight-tenths of 

 a millimeter, show that his specimens were very much smaller than 

 those of 2 and 3 millimeters, obtained off our eastern coast.
