A. solid, finely granulated species, and peculiar on account of its 

 very small umbilicus. The upper whorls are cancellated, as stated 

 by Sowerby, but the radiating costse are much stronger and more 

 conspicuous than the spiral lirae upon and between them. The spiral 

 lirte on the body-whorl are finely granose through being crossed by 

 the oblique lines of growth, although this feature is not mentioned 

 in the brief original description.

 Hah. — Sandwich Is. Type in B.M, 



This species is not " tenuiter decussata " as described and figured by 

 Sowerbj^, but "ornamented with spiral raised striae" (Pease), with 

 still finer interstitial striae, and the lines of growth are only faintly 

 apparent. The umbilicus is moderately large and finely grooved 

 within.

Hal. — Chikewa, Boshiu, Japan. 



A very distinct species, very narrowly perforate, with the last 

 whorl "sculptured with many subequal spiral cords" (Pilsbry). 

 Only the upper whorls are cancellated.

Hah. — Port Jackson and Camp Cove, New South Wales. Type 



in B.M. 



A thin, widely umbilicated species, very finely spirally striated, 

 and with the spire strongly cancellated ; the body- whorl is broad 

 and the aperture rather patulate.

The original figure of this species is quite useless, but that given by 

 Eecluz, from a specimen he received from M. Potiez, is a very good 

 representation of the previous species ( V. Recluziana) excepting that 

 the spire does not show the cancellation. This, however, is accurately
