THE MOLLUSCA—HEDLEY. 469 
Named in honour of the brilliant American Conchologist, who 
has so successfully laboured to place the systematic study of the 
Mollusca on a more scientific basis. 
CYLINDRA DACTYLUS, Linne. 
Tryon, Joc. cit., p. 197, pl. lvii., figs. 658, 664 ; Garrett, Joc. cit., 
pp. 7, 65. 
Three specimens from the Funafuti lagoon. 
Garrett found this at Fiji, Tonga, Samoa, Gilberts, Carolines, 
Society, Paumotus, and Hawaii. Melvill and Standen quote it 
from the Loyalties.* Examples from Woodlark Island (British 
New Guinea), and New Oaledonia, are contained in this Museum. 
ERATO SCHMELTZIANA, Crosse. 
Tryon, Man. Conch. v., 1883, p. 11, pl. iv., figs. 54, 55.

MARGINELLA SANDWICENSIS, Pease. 
Tryon, Joc. cit., p. 45, pl. xii., fig. 69. 
Several dead shells were picked up on the beach of the Funafuti 
lagoon. 
Tryon reports it from Hawaii and Fiji. 
MARGINELLA I0TA, sp. nov. 
(Fig. 41). 
Shell ovate, truncate anteriorly, white, 
smooth. Spire slightly exserted. Aperture 
comparatively wide. Outer lip thick, sin- 
uate, smooth within. Inner lip with three 
principal anterior plications and several 
remote subsidiary ones, deep within. 
Length 1:5, breadth ‘95 mm. 
Three specimens from the sand of the 
lagoon beach. 
The only Marginella comparable in 
size, known from the tropical Pacific, is 
M. mariei, Crosse, whose broad shell and 
immersed spire easily distinguish it.
