Harpa punctata, spec. nov. PI. vi., figs. 3, 3a, 3b. 
Shell roundly-ovate, rather thin, smooth, glistening, of four. 
and a-half whorls. Nucleus one turn and a-half, slightly mam- 
millate, apex inserted, first whorl rather excentric, next half- 
whorl marked off from the first by a depressed scar; suture 
simple and distinct; distinguished from spire-whorls by its 
smoothness, but for minute sublenticular longitudinal striz, and 
by absence of ornament. Spire-whorls two, gradated, with a 
marked very slightly rounded angle, behind which the first turn 
is subconvex, becoming gradually less so, the second is subcon- 
cave, and in front of which both are slopingly subconcave ; very 
minutely longitudinally striated under the lens, best seen behind 
the angle, and still more minutely spirally incised. On the 
second spire-whorl are also erect reflected curved scales, at 
gradually increasing intervals, best seen behind the angle, and 
continuous anteriorly with slightly prominent subvaricose longi- 
tudinal strie. Body-whorl ventricose, slightly excavated close to 
the suture, forming a slightly rounded angle, then uniformly 
slaping-convex ; surface divided into ten longitudinal areas by 
the remains of slightly projecting lips, which behind the angle 
form erect, rounded, slightly-reflected plates, the earlier ones 
more and more worn away ; the areas finely longitudinally and 
spirally incisedly striate. Aperture large, nearly plano-convex ; 
outer lip uniformly convex, simple, very slightly thickened out- 
side, rather more so about two lines within, edge almost sharp ; 
posteriorly ascending for two lines, slightly reflected and pointed, 
and forming a marked notch at the suture. Columella slightly 
convex behind, nearly straight in the anterior half, excavated in 
the lower fifth. Inner lip distinct, smooth, with callus increasing 
in thickness from behind forward ; posteriorly it forms a short 
sinus with the ascending outer lip, then is applied spreading 
somewhat and uniformly over the body-whorl ; in the lower half 
with a free margin least marked where it crosses the varix of the 
notch, then slightly inflected and incurved to the extremity of 
the columella. Anterior notch distinct and everted and recurved. 
Ornament, nucleus, and spire-whorls of a uniform salmon tint. 
The latter and the body-whorl closely dotted with small deep 
chestnut spots, their spiral diameter twice as great as their longi- 
tudinal, arranged in longitudinal series so that the dot of each is 
opposite the space in the next. The body-whorl has also two 
broad salmon-coloured spiral bands, one from the back of the 
aperture to a little above the middle of the lip, the other from a 
little above the middle of the aperture to the lower third of the 
lip. Just behind the remains of previous lips in these bands are 
crescents of dark chestnut, and similar crescents are found here 
and there on the body and spire-whorls close to the suture.
