Description. — "Test plano-convex, moderately vaulted; last 

 volution consisting of seven or eight chambers, with very slightly 

 •depressed septa; septa more curved upon the superior (flat) sur- 

 face; aperture a sm:all, neatly shaped arch at the margin of the 

 -ultimate segment. 



"Diameter, 0.36-1. 13 mm." (Bagg.) 



Remarks. — ^"The above species shows great variation. Pro- 

 fessor Brady considers that the more convex varieties merge into 

 TruncatuUna refulgens, while flattened forms resemble Trunca^- 

 tulinu ■WuellerstorH. The regular-built convex varieties constitute 

 1:he Tnmcattdina boueana of d'Orbigny, and the less regular the 

 TrumcaPidina variabilis of the same author." (Bagg.)
