756 LIMESTONES AND TUFFS OF MALEKULA, N.H., 



PoLYTREMA PLANUM Carter. (Plate xL, fig.ll). 



This encrusting foraminifer, so common as a reef-former at the 

 present day, has ah-eady occurred in the fossil condition in the 

 Miocene limestones of Wai Malikoliko and Wai Bubo, Santo, 

 New Hebrides.^' It now occurs in the Miocene limestone at 

 Laleppe, Malekula, associated in its characteristic way of laminar 

 intergrowth with a calcareous alga; and also in the Post-Miocene 

 limestone of Port Stanley, Malekula, where it also played an 

 important part in building up the rock. 



LiNDERiNA cf. BRUGESI Schlumberger. 



Linderina b7'ugesi Schlumberger, 1893, Bull. Soc. Geol. France, 

 ser.3, Vol.xxi. pl.iii. fig. 9. 



Our specimens occur in the friable limestone from Bartaleppe, 

 Malekula, and there is very little doubt that they belong to 

 Sclilumberger's species. In median section Linderina can be 

 separated from Gypsina by the continuous nature of the 

 chamberlet-wall in the former, whereas in the latter the cells 

 are entirely cut off from one another, excepting for the mural 

 perforations. 



A species of Linderina from the Miocene limestone of Borneo 

 has already been recorded and figured by Newton & Holland,! 

 and a more doubtful occurrence of the genus was noted from 

 Riu-Kiii Island by the same authors. J Schlumberger's origina 

 specimen of L. brugesi came from the Upper Eocene of Bruges, 

 Gironde. 



Lepidocyclina angularis Newton k Holland. (Plate xxxviii., 



fig-3). 



L. angularis Newton & Holland, 1902, Journ. Coll. Sci. Tokyo, 

 Vol.xvii. Art. 6, p.lO, pl.i. figs.1-6; pl.iii. fig.7. 



This species is characterised by its depressed central area, the 

 outer boundary of which is marked by strong calcified pillars,
