GYROIDINA SOLDANn d'Orbigny, var. NITIDULA (Schwager) 



Plate 8, figures 9 a-c 



Rotalia nitidula Schwager, Novara-'Exped., Geol. Theil, vol. 2, 1866, p. 263, 

 pi. 7, fig. 110. 



Variety differing from the typical in the very narrow last-formed 

 whorl with the sutures very strongly oblique. 



It may be useful to distinguish this variety which occurs especially 

 in the Pliocene of the Pacific, Kar Nicobar, New Guinea, etc., as well 

 as in the present oceans. It is rare in the Atlantic. A specimen 

 which may be referred to this variety is shown on Plate 8, figure 9. 

 It is close to the form which Brady refers to '^Rotalia broeckhiana 

 Karrer," but the spire in our form is low. All are probably the same.
