120 MELVILL AND STANDEN : SHELLS FROM LIFU. 
R. (Moerchiella) spiralis Souverbie.—One specimen seems 
to approach &. artensts Montrouzier, just mentioned. 
R. (Pyramidelloides) miranda Adams.—Several. Probably 
synonymous with &. zzsolzta Desh. from the Mauritius. A 
curiously sculptured and very beautiful species. 
Barleeia Chasteri sp. nov. (PI. III., fig. 22). 
B. testa minuta, levissima, vix pellucente, anfractibus guingue, 
levibus, ventricosults, ochraceo-brunnets, infra suturas trans- 
versim vitta calcarea succinctts, simul ae apud basin an- 
Jractus ultimi, apertura rotunda, pupineformi, labro fere 
continuo, inci assato. 
Long. TG ail. at. 3 well: 
ffab., Lifu (in shell-sand). 
Twenty to thirty specimens of this pretty little shell have 
come under our observation. Some specimens are of a darker 
ochreous-brown colour, and therefore show the contrast with the 
chalky white transverse band just below the sutures more dis- 
tinctly than the paler forms. ‘The whorls are five in number, 
and the whole shell is extremely smooth, barely translucent ; 
whorls slightly ventricose ; operculum unknown. 
We think (as pointed out to us by Mr. Edgar Smith) 
that the genus ar/eeva fits this species more nearly than any of 
the other Rissoid sectional genera or sub-genera, although we 
believe the seas of Europe alone contain nine-tenths, if not all, 
the hitherto described species of the genus. M. Fischer in- 
cludes Fairbankia bombayana Blanford, however, with Bar/eeza, 
and it is probable that it is generally diffused over the tropical 
area—indeed, in Paetel’s Catalogue, some Mauritian and Cali- 
fornian species, not known to us, are included likewise.
