FROM THE hues AT FUNAFUTI. 183 
Unlike the other Foraminifera, this form is conspicuously 
absent from dredgings taken immediately inside the rim of the 
atoll on the opposite sides of the lagoon, and increases in numbers 
and character towards the middle of the lagoon. 
S. frondescens is apparently restricted to the S. Pacific.

This species is not a common form, but it is generally distri- 
buted in tropical and subtropical areas. It was found by the 
‘Challenger’ at five or six stations amongst the coral-reefs of 
the Pacific. 
The specimens found in the lagoon at Funafuti are typical. 
The test sometimes branches towards the end.

The particular part of the lagoon where this species appears 
to thrive best is near the middle, from sample 10, and four miles 
from the nearest reef; at this place the Haddonie have a 
peculiar habit of sheltering between the fronds of Halimeda, and, 
by adhering at various points to the joints, cement them into 
a more or less coherent mass.
