Stations 4, 5, 6, 9. 



Very rare, a few small but typical specimens in the N.Z. area only. 



254. Bolivina inflata, var. arenacea, nov. PI. IV, figs. 31-33. 



At Stations 2 and 6 (N.Z.) and at Station 55 (Ant.) a few minute arenaceous 

 isormorphs were found. They are slightly larger than the hyaline form, but 

 otherwise correspond, except in the constitution of the test, which is built up 

 almost entirely of ferruginous cement in which hardly any trace of mmeral 

 grains can be seen under a fairly high power. The shell-wall is extremely thin 

 and delicate.

255. Bolivina plicata, d'Orbigny. 



Boliviua plicata, d'Orbigny, 1839, FAM. p. 62, pi. viii, figs. 4-7. 



Heron-Allen and Earland, 1914, etc., FKA. 1915, p. 648. 



Stations 2, 3, 5, 6, 8-10. 



Fairly plentiful, very good and typical specimens at Stations 5 and 6. 



256. Bolivina reticulata, Hantken. 



Bolivina reticulata, Hantken, 1875, CSS. p. 65, jal. .xv, fig. 6. 

 MiUett, 1898, etc., FM. 1900, p. 547. 



Stations 6, 7, 9-11. 



The records are few and the specimens are nearer Hantken's original figure 

 than Brady's. With a few exceptions they all represent a variety with a sharply 

 truncate marginal edge, and practically parallel faces. This gives the test a very 

 compressed appearance.
