102 MELVILL AND STANDEN : SHELLS FROM LIFU. 
M. (Costellaria) dimidiata Sowb.—A few good specimens. 
M. (Costellaria) discoloria Chemnitz.—Common. 
M. (Costellaria) exasperata Reeve. —Abundant, but mostly 
of a variety we characterize as follows :— 
M. (Costellaria) exasperata var. Hadfieldi var. nov. 
(PL Ail fie 4-) 
Shell turreted, eight or nine ribbed, differing from the type 
in being dark-brown, banded at the line of the sutures of the 
upper whorls, and also twice transversely banded at the last 
whorl. Occasionally specimens occur wholly suffused with 
dark-brown. 
An extremely common form at the Loyalty Islands, several 
hundred specimens having been forwarded by Mr. Hadfield. 
M. (Costellaria) modesta Reeve.—A few. 
M. (Costellaria ?) nitidissima sp. nov. (Pl. IIL, figon 
M. testa minuta, perlevi, nitente, bvunnea, tenut, anfractibus 
sex, paullum ventricosts, longitudinaliter costulatis, apertura 
oblonga, labro extertore vix tncrassato, columella qguadriplicata. 
Long., 5 mill. Lat., 1°5 mill. 
Hab., Vatu. 
Four specimens from shell-sand, all precisely alike, of a 
very small brown, very shining and smooth shell, longitud- 
inally roundly costate ; columella four-plaited. The species 
may really belong to Volutomitra rather than Costellaria. 
M. (Costellaria) nodilyrata A. Adams.—Several. 
M. (Costellaria) pacifica Lamarck. — Rather larger than 
M. cadaverosa of which it may be but a variety. Many 
specimens. 
M. (Costellaria) semifasciata Lamarck._-Not uncommon. 
M. (Pusia) alveolus Reeve.—Three not quite full grown 
specimens we refer almost certainly to this species; the 
vivid black and white marking, as in JZ. /wsa Reeve, render- 
ing it conspicuous. It is allied both to this species and 
also AZ. Shoplandi Melvill, lately described from Aden. 
M. (Pusia) amabilis Reeve. 
A few good specimens.
