FORAMINIFERA OF THE FUNAFUTI ATOLL. 391 
and having a diameter of 1:8 cm., encrusted with Polytrema 
planum, which has ensured its preservation. 
Dredgings taken near Tutanga (bearing 102° to Tutanga, 
155° to Tegasu), 136 fathoms (1897). 
Fragmentary rock-specimens and Halimeda-joints. One piece 
consisting of an encrusting mass of Polytrema planum measures 
3X2 em. and is 4 mm. thick. The outer surface is smooth and 
of a very pale green colour. ‘lo the under surface a fine speci- 
men of Haddonia torresiensis is attached. 
The smaller fragments bear numerous dark-coloured speci- 
mens of Polytrema miniaceum. 
A fragment of Aleyonarian largely composed of the aggluti- 
nated spicules. 
Associated with these are Sagenina frondescens (on Halimeda) 
and Cycloclypeus Carpentert (form A). 
Dredgings west of Tutanga, 200 fathoms. 
Specimen A 2. 
Two rather massive pieces of organic calcareous rock. and 
fragments of a Gorgoniid stem. 
The largest piece of rock measures 12°5x6xX3°5 cm., and 
consists of large flaky masses of Polytrema planum built in tiers, 
rudely resembling the nest of the wasp (Vespa); with many 
adherent foraminifera, bryozoa, Serpule, brachiopoda (Cranza), 
and alge. Besides P. planum the other foraminifera are Poly- 
trema miniaceum, whose small pustular tests are scattered over a 
large portion of the rock, and Carpenteria serialis, sp. nov. 
(Pl. 35. fig. 3). There are apparently two kinds of alge—one 
a thin, pink, encrusting form, and the other a thread-like or 
filamentose and branching organism rather doubtful in its 
affinity. 
The smaller piece of rock measures 8°5 x 5 x 2°5 em., and has 
a double nodular shape, with a lumpy surface, overgrown with 
Polytrema planum, P. miniaceum, and several species of bryozoa. 
The alcyonarian stems are encrusted with a pink alga, and 
foraminifera (as Carpenteria utricularis, Polytrema miniaceum), 
a sponge, and numerous bryozoa,
