 tion of the well-preserved original ; it seems, therefore, to me not reasonable to create a new species because it is derived from a different locality, but shows again the coincidence of the African and Indian Cretaceous deposits.

Locality. Umtamfuna river, bed e. In India : Pondicherry.

Solarium Wiebeli, nov. sp. Pl. III. fig. 6.

Angle 130°. Number of whorls 5.

The surface perfectly smooth, only the lines of growth are faintly visible ; but neither transverse striae nor ribs can be distinguished, as in Solarium pulchellum, Baily, from the same stratum ; in shape also this species varies much from Baily's Solarium, which possesses gradually widening whorls, whilst in the present species each whorl is double the width of the preceding one.

Locality. Umtamfuna river, bed e.

Turritella (Chemnitzia) Meadii, Baily.

Chemnitzia Sutherlandii, Baily.

Mr. Baily calls a small Chemnitzia, which shows slight spiral lines, Turritella Meadii ; but it is, I think, only a young individual of his new species Chemnitzia Sutherlandii, which can be identified with some varieties of Chemnitzia undosa, Forbes. The last whorls do not show the transverse lines so distinctly ; and altogether it is impossible to find two specimens which show exactly the same ornamentation of surface. The older whorls are always more distinctly ribbed, but not the later ones. In full-grown specimens, the spiral lines, which even in young ones are very feeble, disappear.

EuCHRYSALIS GIGANTEA, Stol.

This is the species erroneously referred by Bailey to Turritella Renauxiana, D'Orb.

Locality. Umtamfuna river, bed e. In India : north of Alundanapooram, east of Anapaudy, Comarapolliam. Trich. & Arr. Gr.

Dentalium, spec.

A small fragment of a smooth Dentalium, which it is not possible to identify with any already described species.
