194 EOCENE MOLLUSCA. 



curvas obliquas sese decussantes gerentibus, ad suturam incrassatis, plicatis: aperturd 

 angustd ; 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 ; but the more elevated posterior 

 margins, the thickened and plicated edges of the whorls in the present species, 

 apparently justify the separation.
