494 FUNAFUTI ATOLL. 
HELIACUS DIscorpDEus, Pease. 
Tryon, loc. cit., p. 21, pl. vi., fig. 6. 
One dead shell from the shore of the lagoon. Previously known 
only from the Paumotus. 
LITTORINA OBESA, Sowerby. 
Tryon, loc. cit., p. 247, pl. xliii., fig. 53. 
In great profusion at and above high water-mark, on stones 
and even tree stems, on the windward beach of the atoll, in com- 
pany with Nerita, Truncatella, and Melampus. 
Recorded by Melvill and Standen from Lifu, by Smith* from 
Rotuma, and shown in this Museum from Eddystone Island 
(Solomons), Vate (New Hebrides), the Gilberts, and Fanning 
Island. 
Mopu.vus tectum, Gmelin. 
Tryon, loc. cit, p. 260, pl. xlviii., figs. 87 — 89. 
One dead shell was found on the beach of the Funafuti lagoon. 
Tryon quotes this from Fiji and Hawaii; Melvill and Standen 
from Lifu. It is in this Museum from New Caledonia. 
RISELLA CONOIDALIS, Pease. 
Tryon, loc. cit., p. 263, pl. 1., fig. 38. 
Dead shells were not uncommon on the sandy beach of the lagoon. 
The species was originally described from the Paumotus. I 
have collected it at Panie, New Caledonia. Schmeltz mentions 
it from Tahiti. There can, I think, be little doubt that the shell 
described twelve years later from Lifu by Montrouziert as Hchi- 
nella gaidei is identical. 
PLESIOTROCHUS SOUVERBIANUS, /scher. 
Tryon, Joc. cié., p. 264, pl. 1, figs. 44 — 46. 
Not rare as dead shells on the sandy shore of the lagoon. 
Originally described from Lifu. 
FossaARUS LAMELLOSUS, Montrouzxter. 
Tryon, loc. ct., p. 271, pl. li., fig. 7. 
Three dead shells were found on the beach of the Funafuti 
lagoon. The type from New Caledonia is described as imperforate, 
but these have a deep and narrow umbilicus.
