 faces of the segments flat or slightly hollowed, peripheral edge square 

 or obtuse-angular; apertural end broad, margin everted, orifice simple.

Genus TUBINELLA Rhumbler, 1906 



Tubinella Rhumbler (Genotype, by designation, Articulina inornata 

 H. B. Brady), Zool. Jahrb., Abteil. Syst., vol. 24, 1906, p. 25.— Cushman, 

 Special publ. No 1, Cushman Lab. Foram. Res., 1928, p. 151. 



Articulina (part) H. B. Brady (not d'Orbigny), Rep. Voy. Challenger, Zool- 

 ogy, vol. 9, 1884, p. 185. 



Test with an ovoid early portion, the remainder of the test nearly 

 straight, cylindrical; partially divided; aperture, the open end of the 

 last chamber; color, bluish-white. 



Recent. 



This genus apparently has developed from a quinqueloculine young 

 possibly through Articulina by acceleration of development. The 

 wall seems to be imperforate and to have the peculiar bluish-white 

 color so characteristic of the Miliolidae.

Test elongate, cylindrical, slightly tapering, the initial chamber 

 elongate, bulbous, rounded at the base, remainder of chambers indis- 

 tinct; wall with very fine longitudinal striae; aperture formed by the 

 open end of the last-formed chamber.

This is a very widely distributed species being known in the 

 Atlantic from a Challenger station off Prince Edward's Island. 

 Except for this record, all the others are from the Mediterranean or 

 the Indo-Pacific.
