As is usual in Kecent material this species shows a very consider- 

 able variation in the shape of the test, which is typically compressed 

 in distinction from the following one, which is more or less globular 

 in shape. Specimens appear to be identical with Recent material 

 from this same general region in comparatively deep water. 



GLOMOSPIRA CHAROroES (Jones and Parker) var. CORONA Cushman and Jarvis 



Plate 2, Figitrbs 8-10 



Olomospira charoides (Jones and Parker) var. corona Cushman and Jarvis, 

 Contr. Cushman Lab. Foram. Res., vol. 4, p. 89, pi. 12, figs. 9-11, 1928. 



Glomospira charoides (Jones and Parker), Whitei, Journ. Pal., vol. 2, p. 187, 

 pi. 27, fig. 8, 1928. 



Variety differing from the typical in having the irregularly coiled 

 later portion in a sort of irregular crown at the end of the test in- 

 stead of coiling about the whole test as in the typical form. 



This variety also occurs in the Cretaceous, Velasco shale of Mex- 

 ico from which we have specimens. It is the form figured by White * 

 from the Velasco. Recent specimens that we have seen, as well as 

 those figured, have the later portion coiling in the long axis of the 

 test after the spiral is completed.

Mus. Bull. 71, pt. 1, p. 114, fig. 175 (in text), 1910.— Cushman and Jarvis, 



Contr. Cushman Lab. Foram. Res., vol. 4, p. 90, pi. 12, figs. 15 a, 6, 1928. 



The figured specimen is evidently megalospheric and may be a 

 distinct species, but the microspheric form should be studied. The 

 uncoiled portion is partially collapsed. 



No further specimens of this species have been found in a further 

 search of the Trinidad Cretaceous. It has been left under Brady's 

 species for the present at least. Franke, however, has described a 

 somewhat similar species as " Lituotuha incertus " from the Upper 

 Cretaceous of Germany. Further specimens may show that Cre- 

 taceous specimens of Germany and America are identical and distinct 

 from the Recent one.
