Characters. — The typical PiduinuUna rej^anda has a troclioid or discoidal 

 shell, formed of about two and a half revolutions, all visible on the upper (spiral) 

 surface, the outermost alone visible on the lower. Outermost convolution con- 

 sisting of six or eight slightly convex segments. Septa (in normal specimens) on 

 the upper surface more or less limbate, the raised line of shell-substance prolonged 

 round the external margin of the segments forming an obtuse peripheral carina. 

 On the inferior surface segments convex, especially the later ones ; septa 

 depressed, often obscure ; surface sometimes tuberculate, sometimes marked by 

 large perforations, radiating from the irregular umbilicus. Peripheral margin 

 almost entire, sometimes lobulate, the peripheral convexity of the ultimate and 

 penultimate segments being most prominent. 



The figured specimen (PI. II, figs. 25 — 27), shows one of the modifications 

 which have fewer chambers than the large forms and are more compact, forming 

 a more or less conical shell, with neatly limbate sutures on the aboral face. It is 

 near P. pulchella (d'Orb., 1829), but of stronger build. 



Occurrence. — Fulvinulina rejjanda, according to the ' Challenger ' Report, is a 

 shallow-water foi^m commonly found at depths ranging from the shore-line down 

 to 200 fathoms, and sparingly down to 1000 fathoms. Egger, in the ' Gazelle '
