This specimen consists of a large limestone-cast exhibiting the 

 basal and penultimate whorls only, the remainder of the spire being 

 absent. The whorls are shallow, infundibuliform, postero-horizon- 

 tally depressed, obtusely angulate at and between the margins, and 

 separated by a deep suture ; the margin of the inner or columella- 

 lip is smooth, rounded, thickened, and excavated ; the aperture is 

 filled with matrix and not definable, but, where this is rubbed down, 

 columella-plications are observed to be present. The surface of the 

 whorls shows indications of one or two obscure spiral bands, which 

 give rise to obtuse angulations apart from that produced by the 

 marginal carination.

Although not quite so rounded in its whorls, this specimen is 

 closely related to a large internal cast in the British Museum 

 (Mantell Coll. 32578) labelled Campanile cf. gigantens, from the 

 Eocene (Lutetian) strata of Verona, Italy, which exhibits three 

 prominent columella-plications extending through its whole axis. 

 The specimen now described was previously regarded as ' a Nerincea 

 of Neocomian affinities ' ; x but a further study of its characters 

 removes all doubt as to its proper place being with the large 

 Cerithiidse, so characteristic of the Eocene Period. That it belongs 

 to this horizon is a fact further strengthened by the presence 

 of Amphistegina and Operculina of. complanata in the limestone- 

 matrix (see § P in the Notes on the Eoraminiferal Structures, etc., 

 p. 177). 



Locality. — Bur Dab (Somaliland). 



Collector.— Mr. E. B. Parkinson. [G. 12053.] 



Matrix. — Cream-coloured limestone, weathering a straw-colour.

This form is represented by a basal fragment possessing four 

 whorls, which have been more or less distorted or compressed through 

 the process of fossilization. The whorls are obtusely angulate on 

 both margins, infundibuliform, deeply sutured, depressed and concave 

 above ; they are of uniform height, with the exception of the last r 

 which is about double that of the others. The base shows two 

 strong columella-plications, and there may be a third, but it is 

 not exposed. The surface of the last whorl possesses distant 

 concentric sulcations, about midway between the lower marginal 

 angulation and the basal area.
