AET. 19 FORAMINIFERA FROM TENNESSEE BEERY AND KELLEY 3 



tinct. Walls stout, arenaceous, with much cement. Aperture a sim- 

 ple hole at the end of the last chamber; there is no evidence of a 

 neck, as in most species of this genus. 



Length, 0.59 mm. 



This species of Reophax looks very like certain species of Hor- 

 7)iosi7ia, but in thin section it is at once evident that it belongs to the 

 genus Beophax. It does not seem to be closely related to any of the 

 described species of the genus. If it should prove to be unique for 

 this part of Ripley it should be of much economic importance.

Test elongate, tapering, small, ratio of length to width about 3 : 1. 

 Chambers slightly inflate giving a rough outline, biserial throughout. 

 Chambers numerous usually about 9 in an adult specimen, have usual 

 Textularian shape with rounder exterior margins. Sutures slightly 

 depressed, fairly distinct; wall arenaceous, fair amount of cement. 

 Aperture simple arched slit on the interior face near point of attach- 

 ment of last chamber. 



Length, 0.86 mm. 



This species, which has been described from the Cretaceous of New 

 Jersey,^ and the Midway of Texas- is the most common Textularia 

 found in the Ripley on Coon Creek. The specimens fit into the 

 species closely.

TEXTULARIA SAGITTULA Defrance. var. COONENSIS W. Berry, new variety 



Plate 2, Figure 3 



Test elongate, tapering, small, ratio of length to width about 2 : 1. 

 Chambers extremely small, numerous, usually about 20 in an adult 

 specimen; chambers form a sharp angle at the margin and are 

 arranged biserially. Sutures distinct, even with the surface, slightly 

 limbate, wall thin hayaline, perforate, colorless. Aperturial end 

 usually not preserved. Where it is present the aperture is a simple 

 arched slit at the line of attachment of the last formed chamber,
