THE MOLLUSCA—HEDLEY. 409 
DELPHINULA LACINIATA, Lamarck. 
Pilsbry, op. cit., p. 266, pl. Ixvii., figs. 1, 2, 4. 
I collected a single worn shell on the sandbank in the centre 
of the Funafuti lagoon. 
It is recorded by Kiener* from New Ireland, by Melvill and 
Standen} from the Loyalty, and there is a specimen in this 
Museum collected by Pére Montrouzier at Woodlark Island, 
British New Guinea. 
NERITOPSIS RADULA, Linne. 
Tryon, op. cit., p. 82, pl. xxix., fig. 68. 
One dead shell was found on the beach. 
Melvill and Standen record this from Lifu. Specimens from 
New Caledonia are described by Fischer. { 
NERITA ALBICILLA, Linne. 
Martens, Conch. Cab. ii., 11, 1889, p. 25, pl. wiii., figs. 1, 2. 
One living example, found in the lagoon. 
This species ranges south along the Australian coast to Sydney. 
Von Martens cites Port Carteret, New Ireland, Solomons, New 
Caledonia, Fiji, Samoa, Tonga, and Tahiti. A specimen from 
Erromanga, New Hebrides, is in this Museum. 
NeERITA MAXIMA, Chemnitz. 
Martens, op. cit., p. 29, pl. vi., figs. 1 —5. 
Two living shells from under stones between tides in the lagoon 
of Funafuti. 
Von Martens quotes for this Jaluit, Marshalls, Fiji, Samoa, 
and Tahiti. 
Specimens are in this Museum from Aneiteum, New Hebrides. 
NERITA PLICATA, Linne. 
Martens, op. cit., p. 63, pl. x., figs. 6 — 10. 
This species occured at Funafuti in great profusion. The wave- 
worn breccia of the outer beach, just above high tide, is its 
favourite haunt. Here a hundred may be gathered from a few 
square feet. Into any crevice they crawl and huddle together 
like a cluster of Helix aspersa when hibernating. Their tenacity 
is wonderful. Often when picking them out of a crevice in the 
coral, I have pulled away the shell and found the foot and 
operculum adhering to the rock, torn from the viscera left in the
