Test typically about 2}^ times as long as broad, only slightly com- 

 pressed, the early, spirally twisted chambers irregular, elongate, 

 but in adults with two to four biserial chambers somewhat more 

 compressed and inflated; sutures distinct, slightly depressed, strongly 

 oblique; wall smooth, finely perforate; aperture narrowly elliptical, 

 with the opening usually somewhat narrowed at the base of the 

 chamber. Length, up to 1.00 mm.; breadth, 0.30 mm.; thickness, 

 0.18 mm. 



The original specimens described by Brady were from the South 

 Pacific region. In our material it has occurred very rarely in the 

 ^/6aiross collections, the only record being Albatross station H3840, lat. 

 17°21'00" S., long. 149°15'00" W., m 1,585 fathoms, vol. m. It 

 has, however, occurred abundantly in the shallow water at some 

 stations, particularly off Fiji, at Viva Anchorage, in 3 fathoms; off 

 Nairai, 12 and 24 fathoms; off Levuka, 12 fathoms; and off Niau. 

 Specimens are common also in 7 fathoms off Rotonga, and are rare 

 at Vivau Anchorage, Tonga Islands, in 18 fathoms. 



VIRGUUNA FIJIENSIS Cushman 



Plate 4, Figure 6 



Virgulina fijiensis Cushman, Cushman Lab. Foram. Res. Special Publ. No. 6, 

 p. 49, pi. 7, figs. 9a-c, 1936; No. 9, p. 31, pi. 5, fig. 5, 1937. 



Test very elongate, slender, six or seven times as long as broad, 

 slightly compressed, somewhat twisted throughout, the later portion 

 becoming more definitely biserial, periphery broadly rounded, slightly 

 depressed, oblique; wall smooth, finely perforate; aperture narrowly 

 elongate, slightly curved, continumg to the base of the inner margin 

 of the last-formed chamber. Length, 1.60 mm.; breadth, 0.25 mm.; 

 thickness, 0.18-0.20 mm. 



The types are from off Nairai, Fiji, in 12 fathoms. 



This is a very elongate, slender species, which keeps the twisted 

 spiral character throughout most of its development.
