456 FUNAFUTI ATOLL. 
TRITONIUM PILEARE, Linne. 
Tryon, Joc. cit., p. 12, pl. vi., figs. 31 - 36; pl. vii., figs. 38, 39. 
A few were found alive in the lagoon. Tryon indicates the 
range of this species as circumzequatorial. Its occurrence in 
every archipelago in the Pacific is therefore to be expected. 
TRITONIUM CHLOROSTOMUM, Lamarck. 
Tryon, loc. cit., p. 13, pl. vii, figs. 47, 48. 
One empty shell from the lagoon beach of Funafuti. This 
species appears to share the geographical range of its predecessor. 
TRITONIUM GEMMATUM, Reeve. 
Tryon, loc. cit., p. 13, pl. vii, figs. 41 — 44. 
A single specimen was taken on Funafuti. 
Tryon cites this from the Paumotus, and Melvill and Standen 
from Lifu. Representatives from New Caledonia and Fanning 
Island are in this Museum. 
TRITONIUM DIGITALE, Feeve. 
Tryon, loc. cit., p. 29, pl. xv., figs. 142, 143. 
Common alive in the Funafuti lagoon. 
Tryon gives Fiji, and Smith* Strong Island, as localities. In 
this Museum it is exhibited from San Christoval, Solomons, 
Aneiteum, New Hebrides, Marquesas, and Hawaii. 
TRITONIUM TUBEROSUM, Lamarck. 
Tryon, Joc. cit., p. 23, pl. xiii., figs. 111 — 113. 
One specimen, alive, from the Funafuti lagoon. 
From Lifu, Melvill and Standen note this species; and examples 
from Woodlark Island and Port Moresby, British New Guinea, 
repose in this Museum. 
TRITONIUM MACULOSUM, Gmelin. 
Tryon, loc. cit., p. 25, pl. xiv., fig. 121. 
One dead shell was found on a western islet of Funafuti. This 
Museum has the species from the Gilberts. 
DIsToRTRIX ANUS, Zinne. 
Tryon, loc. cit., p. 35, pl. xv., fig. 153 ; pl. xvii, figs. 173, 174. 
I did not find this species on Funafuti, but have seen specimens 
collected there by Mr. G. Sweet.
