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



Orhitolites marginalis Lam. sp, 



Textidaria trochus d'Orb. (PI. xli., fig. 15). 



Carpenteria sp. 



Pulvinulina sp. 



Heterostegina depressa d'Orb. 



The age of these rocks is probably Pliocene or later. The 

 foraminiferon Sphceroidma dehiscens, which occurs in 91a with 

 frequency, has not been found in strata below the Pliocene (Jide 

 H. B. Brady). 



No. 102. — "Outcrops at Laleppe, about 900ft. above sea-level, 

 Malekula."^^ 



This is a rather gritty, pale ash-coloured limestone, principally 

 organic, but with an admixture of volcanic products, chiefly 

 glassy. Besides forarainifera, spines of echinoids were noticed in 

 thin slices of this rock. 



The Foraminifera are : — 



Bilocidina cf. ringens Lam. 



Orhulina universa d'Orb.; frequently showing the enclosed 

 embryonic ' globigerine ' stage of the test. (PI. xli , fig. 13). 



Glohigerina bidloides d'Orb. 



G. conglobata Brady. 



Carpenteria sp.; tests much crushed. 



Pidvimdina cf. repanda F. cfe M. sp. 



Ainphistegina lessoiiii d'Orb.; specimens numerous but small. 

 (PI. xli., tig.13). 



Heterostegina depressa d'Orb.; tests fragmentary, common. 

 Probably of Pliocene age. 



No. 107. — " Bedded sedimentary series on the Laleppe Amil to 

 Bartaleppe track at an elevation of about 700 ft.; Malekula."* 



Fine-grained, ash-coloured, foraminiferal tuff's. 



Glohigerina numerous. Specimens apparently all belonging to 

 G. bidloides d'Orb.
