Conus velatus (Cossman, 1889)


Descrizione e caratteristiche:

 

Sehll smooth, oblong, turbinate, somewhat produced at the base, where it presents traces of transverse sulcation: spire conical, slightly elevated, barely exceeding in height a third part of the whole length of the shell : whorls narrow, angulated, and smooth round the shoulders ; the posterior margins much depressed, very slightly concave, and presenting four or five rather coarse, raised, concentric lines, which are crossed and decussated by prominent, curved, wrinkle-like elevations, corresponding with the curvature in the outer lip ; the edge is thickened, and presents a raised border round the suture, plicated by the extension of the marginal wrinkles over the surface. The aperture is narrow ; the outer lip much arched, and sparated from the suture by a wide, moderately deep curvature. The surface of the shell is much eroded, and the lines of growth are consequently more conspicuous than is usually the case ; these, with the decussated lines on the spire, " give the shell," Mr. Sowerby says, " the appearance of having been enclosed in a net or net-veil ; whence the name." (1) 


The specimen from which the figure is taken, and on which the species was 
founded, forms part of Mr. Bowerbank's collection, and is, I believe, unique. In the general character the shell resembles C. deperditus ; but the more elevated posterior margins, the thickened and plicated edges of the whorls in the present species, apparently justify the separation (1). 


Size. — Axis, 1 inch and 4-12ths; diameter, 5-12ths of an inch (1). 


Locality. — Bracklesham Bay (1).
