THE MOLLUSCA—HEDLEY. 401 
south end of the main islet of Funafuti, where the lagoon com- 
municates with the ocean, are some clumps of Millepora rising to 
the surface from about ten or twelve feet. On these is a colony 
of the giant Vermetus, and built in by coral growth are Magilus 
and Galeropsis. Near the Millepora were bushes of Plexaura, 
among whose branches perched Avicula. A sandy flat sheltered 
behind a long shingle bank yielded at low water Mitra episcopalis, 
Murex ramosus and Trochus obeliscus. 
A mile to the north, where the quiet waters allowed mud to 
settle, the gregarious Planaxis sulcatus occurred in quantities. 
Cypraea moneta and C. caput serpentis were here abundant, and 
to the rocks in the neighbourhood adhered Chama. Nearer the 
village, at the spot sketched on p. 71, I found as dead shells most 
of the small species described as new. 
A few small reefs in the lagoon opposite the village were 
excellent collecting grounds. The sandy patches among the coral 
were inhabited by Strombus luhwanus and S. floridus, and by 
numerous Cerithide#, among which the large C. nodulosum was 
conspicuous. What seemed a brilliantly coloured worm disap- 
peared at a touch with a snap and proved to be the animal of 
Tridacna elongata seen through the opening of the valves sunk in 
coral. Loose coral blocks rolled over and split up yielded a 
harvest; under the block might be Conus rattus, C. lividus or 
Mitra limbifera, and within it Lithodomus and Arca. 
In a few hours spent on the leeward islets of the Atoll, I 
gathered on the beach several large but dead species of Cypraea, 
Oliva and Conus, which I had not elsewhere encountered. ‘A 
glimpse of a rich and distinct deep water fauna was afforded 
by a few hauls of the tangles in 80 — 40 fathoms on the western 
outer slope of the Atoll. Almost everything here collected appears 
to be new to science. 
The sole representative of a fluviatile fauna was a species 
of Melania which occurred in some abundance in the native 
wells. 
Mr. George Sweet has kindly allowed me to inspect a collec- 
tion of shells he made on Funafuti in 1897. I have been able 
in several cases to increase my list by species which he took, but 
which [ had not seen. 
CEPHALOPODA. 
I was unable to secure any specimens of Cephalopoda at Funa- 
futi, though I observed traces of them, as beaks thrown up on the 
beach and ink in the hands of the natives (p 64). Pictures of an 
Octopus were recognized by the natives as “‘feki,” and of a Loligo 
as “mofeki.” I was told that on rare occasions empty Vautilus
