THE MOLLUSCA—HEDLEY. 4929 
Strompus sAMaR, Dillwyn. 
Tryon, loc. cit., p. 121, pl. viii., fig. 88. 
Mr. G. Sweet procured one specimen. 
STROMBUS LUHUANUS, Linne. 
Tryon, loc. cit., p. 122, pl. viii., figs. 91, 92. 
Abundant alive on sandy patches between rocks in the lagoon 
of Funafuti. The natives call it ‘‘paneia” and esteem it as 
food. 
Tryon quotes it from New Guinea and Fiji, and Melvill and 
Standen from Lifu. It extends along the Australian coast south 
to Sydney.* 
PTEROCERA AURANTIA, Lamarck. 
Tryon, loc. cit., p. 124, pl. ix., fig. 5. 
One imperfect but recognisable specimen from Funafuti. 
Schmeltz quotes this from Samoa and the Carolines.j It is in 
this Museum from Fiji. 
PTEROCERA BYRONIA, Gmelin. 
(Fig. 18). 
Tryon, Joc. cit., p. 124. 
A native guided me to the haunt of this 
mollusc, a gravel flat on the western side of 
the lagoon, on which the water was waist- 
deep at low tide. Here I collected numerous 
living examples. All the older specimens, though 
alive, had lost the fingers of the shell, which dis- 
figured them almost beyond specific recognition. 
(Fig. 18). Mr. Whitelegge has pointed out to me 
that the callous lining of the aperture is every- 
where perforated by some vegetable organisms, 
probably alge. He suggests that their action 
has resulted in these mutilations. 
On the opercula of most specimens were seated 
a couple of Hipponyx australis, Quoy. 
The natives, who termed it “karea,” valued it for food both 
raw and roasted, and in ancient times used it as an edge for 
various implements. By mistake, I have referred to this species 
in preceding pages (pp. 67 and 263) as P. lambis. 
Cuming collected this species in the Society islands, the Chevert 
Expedition in Torres Straits, and specimens have been received 
by this Museum from Erromanga, New Hebrides.
