A small turreted shell, which numbers from eight to ten convex whorls, each 
being ornamented by 10-18 transverse ribs and 7-9 spiral, sharp, and slightly 
undulating ridges. In young specimens the ribs are less numerous, and increase 
gradually with the size of the whorls. The spiral ridges are sometimes nearly equal, 
but more frequently some of them, especially the middle ones, alternate with finer 
ridges, which also cover the basis of the last volution. 
The aperture is oval, anteriorly somewhat produced and effuse. It has not 
been seen quite perfect in a full grown specimen. The small one represented on 
Plate XVI, Fig. 6, although having the shell surface somewhat obliterated, has a 
thin but distinct varix on the outer lip externally; no varix has been observed on 
any of the preceding whorls. The inner lip is comparatively thin and smooth. 
Until good and full grown specimens of this species have been found, its 
determination as Sandbergeria must remain doubtful, although the great similarity 
between the same and the Cerithiwm antecedens makes it very probable. I am not 
acquainted with any cretaceous species which could strictly be compared with the 
above. 
Localities—East of Alundanapooram and near Arrialoor, in soft, whitish 
sandstones; rare. 
Formation.—Arrialoor group.
