116 MELVILL AND STANDEN: SHELLS FROM LIFU. 
C. nassoides Sow. —C. maculosum Mighels. — A few 
specimens of this pretty little species. 
C. salebrosum Sow. — Several, showing much beautiful 
variation. 
C. zebrum Kiener.—Described originally from the Galapagos 
Isles, but we see hardly any difference in the numerous 
Lifu specimens, including the var. de/ectum Sowb., which is 
also represented. 
C. (Vertagus) aluco Linné.— A handsome and _ infrequent 
species. 
C. (Vertagus) articulatum Ads. & Reeve.—Several. 
C. (Vertagus) fasciatum Bruguitre.—A large number of very 
fine specimens. One good and several poor examples of 
the form known as V. martinianus Pfr. 
C. (Vertagus) lineatum Lamarck.—Several specimens. 
C. (Vertagus) obeliscus Bruguitre.—Several specimens in 
poor condition. 
C. (Vertagus) semi-nudum Sowb.—Several. A form allied 
to C. obeliscus and differing slightly in sculpture. 
C. (Lampania) lacteum Kiener.—Plentiful. 
C. (Lampania) piperitum Sowerby—Plentiful. 
C. (Lampania) zonale Bruguitre.—Several. 
C. (Pyrazus) palustre Linné.—Two specimens in poor 
condition, 
Bittium sp.—Several specimens of a form near B. abruptum 
Watson. Probably a new species, but we hesitate at 
present to describe it as it does not seem to possess many 
salient characters. 
Potamides caledonicus Jousse.—One small specimen only. 
Cerithiopsis sinon Bayle. (Pl. I., fig. 3).—Several speci- 
mens of a remarkably beautiful shell, which appears to be 
so scarce and little known that we give a figure of it. It 
was originally described as C. c/athratus Ads., and in the 
British Museum there are three tablets so named; but 
Bayle preferred the change on account of this name being 
pre-occupied by a fossil species.
