274 MELVILL AND STANDEN: SHELLS FROM LIFU. 
A small, very compact globular species, attenuate, however, 
towards the apex, the remaining whorls, which are compressed 
at the sutures, being very closely papillose with regular longi- 
tudinal papillary ribs, spirally crossed with liree, the canal is very 
short, callous at the base and stained dorsally with darker ochre- 
brown, mouth round, outer lip denticled within with teeth 
that extend as strize some way into the aperture. Five specimens.

Long., 13, Lat. 5 mill, sp. maz. 
A polished white shell, usually seven whorled, most of the 
many specimens are, however, somewhat worn or broken at the 
apex, the aperture is ovate, peristome hardly callous, outer lip 
thickened and much denticulate within, the denticles extending 
in the form of striz far into the mouth. There is a sutural 
tooth, and the columella is twice denticled towards the base, 
the canal being short. Occasionally pale ochraceous transverse 
spots exist round the sutures, and, dorsally, upon the last whorl 
a beautiful latticed pattern is with a lens observable in the 
smooth substance of the polished shell, this pattern being 
absent in the middle of the whorl. 
We have great satisfaction in uniting with this species the 
name of the Rev. Lewis Shackleford, who has rendered us great 
assistance in many ways.
