THE MOLLUSCA—HEDLEY. 415 
ScaLa OvALIS, Sowerby. 
Tryon, op. cit., p. 69, pl. xiv., fig. 40. 
With doubt I refer here a species obtained on the lagoon shore. 
SCALIOLA LAPILLIFERA, Sp. nov. 
(Fig. 8). 
Shell ovate conical, broad for the genus, 
white, thin and translucent. Whorls seven, 
rounded, the earlier closely coiled, the later 
looser, surface obscurely marked by growth 
strie. Apical whorls smooth and bare ; the 
rest beset with adherent sand grains more 
closely disposed about and below the peri- 
phery. Aperture round, free from the preced- 
ing whorl, with expanded and reflected lip. 
Length 2, breadth 1 mm, 
Three examples from the sandy beach of 
the lagoon, 
This is smaller and proportionately broader 
than other Scaliola and especially differs by 
the almost solute whorls. It is less coated 
with adherent matter than S. caledonica. 
TANTHINA, sp. 
Specimens of an Janthina too young to determine specifically 
occurred on the outer beach. 
NaTICA VIOLACEA, Sowerby. 
Tryon, Man. Conch. viii., 1886, p. 18, pl. iii., fig. 41. 
One dead and broken example from the beach of the lagoon. 
Tryon quotes this from Fiji; Melvill and Standen from Lifu. In 
this Museum it is represented from the Bampton Reef, Coral Sea 
and New Caledonia. 
NATICA MAROCHIENSIS, Gmelin. 
Tryon, op. cit., p. 22, pl. v., figs. 74-96 ; pl. vii., fig. 36; pl. viii., 
fig. 49. 
Several dead shells occurred on the lagoon beach. 
Melvill and Standen quote this from Lifu. In this Museum its 
Australian range is shown to be from Torres Straits to Sydney, 
and it is also represented from the New Hebrides, New Caledonia 
and Hawaii. 
NatviIcA MAMILLA, Linne. 
Tryon, op. cit., p. 49, pl. xv., fig. 43; pl. xvi., figs. 46, 48; pl xvii, 
figs. 65, 69. 
One specimen was obtained attached to a native ornament as 
described ante p. 247.
