AMPHISTEGINA LESSONII d’Orb. 
Vavau. — Vavau is elliptical in outline, highest in the northern por- 
tion, where it reaches 500 ft. The southern shore is deeply indented 
and denudation has separated off numerous small islands from the main- 
land. Four terraces are visible. 
Ist terrace. Organisms somewhat indistinct. They consist of Polyzoa, 
echinoderms, and the following 
Foraminifera : MILIoLina FERUSSACI d’Orb, sp. 
CARPENTERIA, somewhat indistinct. 
GLOBIGERINA. 
?GauDRYINA, a textularian form, probably belongs to 
this genus. 
GYPSINA. 
POLYTREMA MINIACEUM Pallas, sp. 
? GYPSINA GLOBULUS Reuss, one indistinct specimen. 
2d terrace, ? 310 ft. Lithothamnion, Polyzoa, Gasteropoda. 
Foraminifera : TEXTULARIA. 
GYPsINA, numerous specimens. 
CaRPENTERIA. 
POLYTREMA MINIACEUM Pallas, sp. 
MILIoLINA. 
2d terrace, 1 350 ft. Polyzoa, echinoderm spines, Lithothamnion. 
Foraminifera : Mintonina, several specimens. 
CARPENTERIA. 
? GLOBIGERINA CONGLOBATA Brady (or possibly SpHa@- | 
ROIDINA BULLOIDES), one specimen only. , 
AMPHISTEGINA LESSONII d’Orb, one specimen. 
2d terrace, 360 ft. Numerous fragmentary organisms embedded in a 
crystalline matrix. Lithothamnion is the most abundant organism. 
Kchinoderms, Gasteropoda, and annelids (?) are also present. 
Foraminifera : PoLYTREMA MINIACEUM Pallas, sp. 
CARPENTERIA. 
AMPHISTEGINA LESSONI d’Orb. 
GLOBIGERINA, one specimen enclosed in an annelid (?) 
tube. 
GYPSINA. 
3d terrace. Highest point, north shore. The only organisms are 
alcyonarian spicules, and of these the rock is mainly composed.
