Tbe specimen from this locality is shorter than th at figured by
Eeeve, and almost as stout as N. mucronata, A. Adams, Avbicb is
very closely allied.

Ih e scnljiture is of a more delicate character than obtains in
P. textus, and the spire is more graceful.

Shell minute, pyramidally ovate-fusiform, pale pinkish yellow.
Whorls 8 ; three apical convex, smooth, tbe rest also convex, divided
by a deep suture, longitudinally ribbed and transversely ridged.
Costæ somewhat oblique, rounded, broader than the interstices,
about twelve in number on the penultimate volution, rather obsolete
towards the lower part of the last. Spiral liræ well raised,
squamose, generally four in number on tbe upper whorls, and about
eleven on tbe last, alternating witb more slender ones in the interstices.
Last wborl rounded above, contracted below tbe middle,
witb a conspicuous scaled ridge around tbe cauda. Aperture light
pink, ovate-subpyriform, contracted anteriorly into a narrow, oblique,
short, recurved canal. Columella subperpendicular, very little
arcuated, coated witb a th in pinkish callus. Outer lip not much
thickened, crenulated at the edge, and armed within witb about
ten fine liræ, which run far within the aperture, but do not reach
tbe margin of the labrum. Length 11-4 millim., greatest width 6 /

This species belongs to the same genus as another form described
by myself as Fusus ? abnormis. On further consideration I am of
opinion th at they would be more correctly placed in the genus
Coralliopliila. Tbe present species is smaller and more coarsely
sculptured than C. abnormis from tbe Andamans.
