194 EOCENE MOLLUSCA. 
curvas obliquas sese decussantes gerentibus, ad suturam incrassatis, plicatis: apertura 
angusta ; labro valde arcuato, postice late emarginato. 
Shell 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 separated 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.” 
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 ; hut the more elevated posterior 
margins, the thickened and plicated edges of the whorls in the present species, 
apparently justify the separation.
