MELVILL AND STANDEN : SHELLS FROM LIFU. 295 
the mouth is brown within, columellar margin plain. Likewise 
the sinus on the outer lip is inconspicuous, small and rounded. 
Three specimens. (Airos, plain, simple.) 
C. longa sp. nov. (PI. X., fig. 40). 
C. testa attenuata, prolongata, solidula, brunnea, anfractibus 
novem vel decem, ventricosulis, ad suturas timpressis, longt- 
tudinaliter crassicostatis, costis paucts, sptraliter bt- vel tri- 
Jilostriatis, ultimo anfractu medio usque ad basim filo-striato, 
strits duodecim vel tredecim accingentibus, apertura tri- 
angulart, sinu extenso, canalt brevi, labro exteriore cras- 
stusculo. 
Long., 5 mtll., Lat., 1°50 mill. 
A small brown attenuate shell, being long in proportion to 
its width, of the same facies as the Australian C. Letourneuxiana 
Crosse, but smaller, more approaching in this respect C. zacrusta 
of Tenison Woods, from Tasmania, the whorls are (probably) 
nine or ten, but all our many specimens are worn at 
the apex. The whorls are ventricose, longitudinally few and 
thick ribbed, impressed at the sutures, crossed spirally with few 
(three or four) spiral lines, which, at the junction with the 
longitudinal ribs are pale and shining. The last whorl has 
altogether twelve or thirteen such spiral revolving lines. The 
canal is short, aperture triangular, this appearance caused by the 
wideness of the sinus. The outer lip is incrassate, as in most 
of this section. The specimen in most perfect condition, 
which is therefore taken as the type, is not so attenuately 
long as some others. 
C. Rogersi sp. nov. (Pl. X., fig. 41). 
C. testa oblongo-fusiformi, colore valde variabilt, nunc pulchré 
pallide rosea, nunc ochracea unicolore, nunc spiraliter brunnea 
multivittata, anfractibus sex, apicali rubro-coccineo vel fulvo- 
ochraceo, vitreo, ceteris angulato-costatis, undique spiraliter 
liratis, liris majoribus ad angulos costarum, suturis tm- 
pressis, apertura oblonga, labro simplice, sinu perinconspicuo, 
sepius absente. 
Long., 4°50 mill. Lat., 1°50 mull.
