Variety differing from the typical in having the surface entirely 

 smooth. 



This occurs with the typical form at many stations. The only 

 record from the Atlantic is that from the Challenger station off Prince 

 Edward's Island given by Brady.

 Nubecularia (part) H. B. Brady (not Def ranee) Rep. Voy. Challenger, 



Zoology, vol. 9, 1884, p. 133. 



Test elongate, uniserial; initial end coiled or milioline; chambers 

 distinct, simple; wall imperforate, porcellanous, with sand grains 

 attached to the exterior; aperture at the end of an elongated tubular 

 neck with an everted phialine lip, the apertural opening with a series 

 of inwardly pointing teeth. 



Recent. 



This genus is only known from the Indo-Pacific. 



Genus TRILOCULINA d'Orbigny, 1826

 Lamarck), Ann. Sci. Nat., vol. 7, 1826, p. 299. — Cushman, Special Publ. 

 No. 1, Cushman Lab. Foram. Res., 1928, p. 151. 



Miliola (part) Lamarck Ann. Mus., vol. 5, 1804, p. 351. 



Miliolina (part) Williamson, Rec Foram. Great Britain, 1858, p. 83 (and 

 later authors). 



Test with the early chambers quinqueloculine, at least in the micro- 

 spheric form, later ones added in the planes 120° from one another, 

 the third of each series added in the plane of the third preceding and 

 covering it so that the surface of the test is composed of but three 

 visible chambers, interior not labyrinthic; aperture simple, typically 

 with a bifid tooth. 



Triassic to Recent.
