Shell oblong, smooth, of an uniform light brown colour, whitish 
within ; a narrow interrupted white band proceeds from the middle 
of the margin of the outer lip and continues along the posterior edge 
of the volutions to the apex ; a less defined band traverses the dor- 
sum more anteriorly, and terminates at the middle of the inner side 
of the aperture; spire acuminated, comprising more than one half 
the length of the shell; volutions eight to nine, slightly convex, su- 
ture a little elevated; aperture rather wide, shining, broader poste- 
riorly ; outer lip whitish, and thick externally, edge sharp, violaceous 
for a little distance within, with six or seven linear denticulations ; 
inner lip, a fine whitish varix extends from the curve of the aper- 
ture to the anterior point of the channel; within this varix, at its 
centre, are five or six denticulations, closely set, parallel, prominent, 
proceeding over the columella, whitish at their edges, the inter- 
stices and the portion exterior to them being of a reddish brown 
colour; channel projecting, narrow, slightly recurved, with a dark 
violaceous colour within ; a number of rather strong striz pass from 
the inner side of the aperture to the edge of the anterior half of the 
outer lip. 
Length, 5°, of an inch ; width, 29, of an inch.

I have seen but one of this characteristic species: the aperture is 
allied in form to that of Columbella Puella, Sowerby. It may be 
convenient to readers to state, that the species Col. Puella is by acci- 
dent, in the index of the ‘Thesaurus Conchyl.’ of Sowerby, jun., 
entered as Col. Nympha.

Shell oblong-ovate, of a dull white colour ; spire acuminated, form- 
ing about one-half the length of the shell; volutions six to seven, 
which, with the last volution, the columellar side of the shell forms 
an even convexity; the first four or five whorls are of a rose or 
bluish-pink colour, minutely longitudinally striated ; the others are 
smooth, with somewhat distant fine brown lines, seven, eight, or so 
in number, passing spirally and continuously from just within the 
outer lip along the three last whorls, to the commencement of the 
pink striated volutions ; aperture moderately wide and long, rather 
straight ; outer lip sharp at its edge, forming a notch at its junction 
with its next whorl, thickened externally, without denticulation ; 
inner lip also edentulate, smooth, shining, externally forming a rather 
thick, slightly elevated varix, which extends to the extremity of the 
channel, and from the whole length of this varix fine strize pass over
