“NEOBUCCINUM TENERUM.
(Pl. I., figs. 2, 2a.)
Shell small, ovately fusiform, thin, subpellacid, horn-colour, covered with a very thin periostracum, exhibiting somewhat remote, slender, threadlike, arcuate, longitudinal liræ, and rather obscure spiral striæ between them. Whorls 6½ convex, the first 2½, forming the large protoconch, smooth, glossy; the rest not shining, separated only by a slightly oblique suture, the last rounded above, contracted anteriorly; aperture subpyriform, acuminate above, and produced anteriorly into a short, open channel; labrum just a trifle thickened, brownish white within, gently curved in the middle when viewed laterally, very slightly faintly expanded, with a very shallow, broad, indistinct sinuation towards the suture; columella curved above, rather straight below the middle, covered with a thin glossy callosity. Length, 15 millim.; diam., 7; aperture, 6.5 long, 3.3 broad. Operculum (pl. I., fig. 2a) horny, reddish brown, marked externally with lines of growth, and exhibiting a nucleus which is paucispiral at the nuclear end. Lower surface roughened, with a narrow, red, raised ridge, parallel with the outer margin, which is smooth and shining.
Length, 5 millim.; width, 3.
Off Coulman Island, 100 fathoms.
The general form of the shell and the character of the operculum agree with Neobuccinum. It is of thin and delicate texture, and the very fine periostracum is produced upon the threadlike riblets at the upper part of the whorls, forming a sort of fringe below the suture. The riblets are about twenty in number on a whorl. Only a single specimen was obtained.”
