Genus NUBECULARIA Defrance, 1825 



Nubecularia Defrance (Genoholotype, Nubecularia lucifuga Defrance), 

 Diet. Sci. Nat., vol. 35, 1825, p. 210.— H. B. Brady, Rep. Voy. Challenger, 

 Zoology, vol. 9, 1884, p. 133. — Chapman, The Foraminifera, 1902, p. 81. — 

 CuSHMAN, Special Publ. No. 1, Cushman Lab. Foram. Res., 1928 

 p. 168. 



Amorphina Parker, Ann. Mag. Nat. Hist., ser. 2, vol. 19, 1857, p. 278 (fide 

 Sherborn). 



Test typically coiled, planispiral, free or usually attached, consisting 

 of an oval proloculum, with a second coiled tubular chamber followed 

 in the adult by irregular chambers varying more or less with the 

 attached surface. 



Lias to Recent. 



This genus now most abundant in shallow warm waters of the Trop- 

 ics is planispiral, although due to its attachment it frequently builds 

 up material on the outer surface making an asymncietrical test. 



NUBECULARIA INFLATA Terquem 



Under this name Terquem^* describes and figures a peculiar 

 attached form from the coast of France. It has four or five irregular 

 chambers in the last coil. It is not elsewhere recorded. This is not 

 the same as the later N. inUata Brady { = Silvestria hradyi (Millett)). 



NUBECULARIA LUCIFUGA Defrance 



This species described by Defrance from the Eocene of the Paris 

 Basin is recorded in so many forms that it is almost hopeless to try 

 and untangle the synonymy without recourse to the original speci- 

 mens. Brady in the Challenger report mentions that the species 

 occurs in the West Indies, but I have failed to find specimens there 

 that I could refer to Def ranee's species. There are several records 

 from the region of the British Isles. Earland^^ figures the early 

 Cornuspira stage from specimens from shore sand at Bognor, Sussex, 

 England. 



Genus CALCITUBA Roboz, 1883 



Calcituba Roboz, (genoholotype, Calcituha polymorpha Roboz), Sitz. Akad. 

 Wiss. Wien, vol. 88, pt. 1, 1883 (1884), p. 420.— Chapman, The Forami- 

 nifera, 1902, p. 80. — Cushman, Special Publ. No. 1, Cushman Lab. Foram. 

 Res., 1928. p. 168. 



Test adherent, branched, of irregular chambers, more or less 

 cylindrical; wall imperforate; apertures simple, at the ends of the 

 branches. 



Recent. Pacific and Mediterranean. 



This species is known from the Mediterranean, and I have had it 

 also from the Pacific.
