FLABELLINA ELLIPTICA (Nilsson)

text), 1877.— Feanke, Abh. Preuss. Geol. Laudes., vol. Ill, p. 91, pi. 8, 



figs. 14, 15, 1928. 



Test somewhat rhomboid in outline, the early portion distinctly 

 coiled; sutures distinct, slightly limbate, but hardly if at all de- 

 pressed; wall very smooth. Length, 4; breadth, 3.25 mm. 



The very broad, large, smooth form figured here may be referred 

 to the above species, although the early figures are not very definite. 

 A similar form occurs in the Cretaceous of the Gulf Coastal Plain 

 of the United States.

This species described from the Upper Cretaceous of Mexico is 

 also found in the Trinidad collection. The figure given by White 

 shows the costae only between the sutures, and the description reads 

 " with longitudinal ribs crossing the interspaces " as if they were 

 independent on the different chambers. His figure also seems to 

 clearly indicate that the costae are independent of one another on 

 different chambers, as will be seen especially on the left side of the 

 specimen that the different series are not at all aligned. If the 

 figure and description are accurate, it would seem that F. elongata 

 is a synonym of F. decheni Reuss from the Cretaceous of Germany, 

 and that our species figured here from Trinidad and from Mexico 

 is another species. 



The above notes are from our earlier paper. No further material 

 has been found that will help to solve the problem of the identity 

 of this species.
