IV. A Desorterion of the REenF-FRAGMENTS obtained from the 
ReEnF-FACE, FUNAFUTI, upon which ADHERENT FORAMINIFERA 
have been found. 
It seems desirable to keep the description of this series of 
specimens distinct from the foraminiferal sands, chiefly in order 
to show how important a part the larger encrusting and adherent 
foraminifera play in forming the growing reef, a fact which has 
been brought into prominence by the evidence of the Funafuti 
collections, both of the core and the samples dredged up from 
the living reef. These reef-samples are here arranged, firstly, 
in their order of position around the Atoll from N., E., 8., to 
W.., and, secondly, in the order of the depth from which they were 
dredged. The foraminiferal sands which are described subse- 
quently are arranged in order of depth; the bathymetrical 
distribution of the various organisms may thus be readily 
seen. 
N.W. of Pava I., 63 fathoms (1897). 
Two reef-specimens. (1) An encrusting mass of Polytrema 
planum measuring 3 cm. X 2°75 cm. This specimen was evidently 
torn off the reef at a weak point of attachment. It is smooth 
exteriorly, with a slightly undulate surface, and shows on the 
under, attached, surface a rudely concentric manner of growth,
