Nubecularia Cushman (not Defrance), Publ. 311, Carnegie Instit. Washing- 

 ton, 1922, p. 58. 



Test attached, in the early stages with a proloculum and one or 

 more coils of an undivided tubular chamber about it followed by 

 irregularly branching tubular portions with the base flattened and 

 the upper side arched; wall calcareous, imperforate; apertures formed 

 by the open ends of the tubes. 



Recent. Tropical, in shallow water.

 Cornuspiramia antillarum Cushman, Special Publ. No. 1, Cushman Lab. 



Foram. Res., 1928, p. 164, pi. 55, figs. 1, 2. 



Test attached, early portion consisting of a proloculum and one or 

 two chambers, forming a single coil, the main portion of the test con- 

 sisting of an irregular branching tube, slightly convex, with an irreg- 

 ular periphery, spreading over the surface of the test to which it is 

 attached; aperture at the ends of the branches. 



The species is commonly found attached to the short eel grass, 

 Posidonia, in shallow sandy areas in the tropical West Indian region. 

 It was found at Jamaica and at the Tortugas under similar conditions 

 so is probably widely distributed in such habitats. 



It is evidently a deriative from a Cornuspira-\ike ancestry which 

 has become very widely spreading into tubular masses due to the 

 attached habit. The spreading tubes may cover an area of several 

 millimeters. They are flattened on the attached side and gently 

 convex on the other. As all stages were seen on a single leaf of 

 Posidonia, the development must be a rapid one. 



Subfamily 3. OPHTHALMIDIINAE 



Test free, planispiral, in the later stages usually two or more 

 chambers making up a coil, later chambers variously arranged in 

 different genera.
