 Cristellaria subarcuatula Goes (part, not C. subarcuatula Montagu), Bull. Mus. 



Comp. Zool., vol. 29, 1896, p. 57. 



Description. — Test much elongated, earliest chambers close coiled, 

 later ones very early becoming uncoiled and developing an elongate, 

 compressed test, with oblique, slightly depressed sutures; wall smooth; 

 initial end of the test, with a broad flaring plate-like keel, not extend- 

 ing up the peripheral margin, or at least only slightly, bearing nu- 

 merous concentric lines of growth and usually with radial markings 

 as well; aperture radiate, terminal. 



Length up to 5 mm. 



Distribution. — Under the name C. subarcuatula Goes has recorded 

 this species from two stations in the eastern North Pacific, Albatross 

 D3375, 1,201 fathoms, and D3407 in 885 fathoms. 



An examination of Goes' s specimens from these stations shows 

 them to be of the form here figured rather than that shown * by 

 Goes, who simply used as illustrations copies of his figures in the 

 "Report upon the Arctic and Scandinavian Foraminif era " previously 

 published. 2 In reality the specimens found by Goes at these North 

 Pacific stations as is shown by Goes's own material are identical with 

 the form figured by Brady in the Challenger Report as noted above. 

 In many of its characters this form seems worthy of specific rank 

 and its relation to C. obtusata Reuss is very doubtful. I have taken 

 the liberty of raising it to specific rank.

 pi. 6, figs. 14, 15. — H. B. Brady, Rep. Voy. Challenger, Zoology, vol. 9, 

 1884, p. 539, pi. 67, fig. 7.— Flint, Rep. U. S. Nat. Mus., 1897 (1899), p. 315, 

 pi. 63, fig. 4.— Millett, Joum. Roy. Micr. Soc., 1903, p. 253. 



Description. — Test much elongate, compressed, early portion close 

 coiled for a few chambers, then gradually assuming an uncoiled 

 straight form, but with the sutures oblique, the chambers high; 

 surface smooth, sutures slightly depressed, peripheral border rounded; 

 aperture terminal, radiate. 



Length about 2 to 2.5 mm. 



Distribution. — Although not previously recorded from the North 

 Pacific, the species occurred at Albatross station D4875 in 59 fathoms, 

 eastern channel of Korea Strait.
