Remarks. Altogether there are 15 species of Cephalopods described out of this bed, three of which are also found in the Valudayur group of Southern India. Only two species belong to a higher horizon, one of which occurs in India in the Arrialoor group.

Valudayur gr.
There is only one quite strange form ; all the others are found or have their representatives in the Indian Cretaceous series. We see that four out of seven species belong to the lowest beds of the Indian Cretaceous formation, to the Ootatoor group and the Valudayur group, and only one, A. Gardeni, belongs to a higher horizon, the Arrialoor group, which resembles our white chalk.
Cerithium (Fibula ?) detectum, Stol.
Pal. Ind. fig. 192, pl. xv. vol. i.-iv.
This species is found in the same deposits. Shell perfectly smooth, with scarcely visible lines of growth, and very thick.
Locality. Umtamfuna. Bed e.
Cerithium kaffrarium, nov. sp. Pl. III. fig. 5.
Spiral angle 40°. Number of whorls 9.
The shell is very characteristically ornamented — coarse and trans- verse ribs, which are intersected by thin spiral lines. Each of the whorls is contracted near the suture, forming a deep furrow.
Locality. Umtamfuna river, from bed e
Turritella multistriata, Rss.
Sowerbii, Forbes.
Bonei, Baily.
Mr. Baily, in his paper, looks upon this Turritella as a new species ; but it agrees perfectly with Mr. Forbes's original in the Collection of the Geological Society ; his figure is not very clear, which may account for the making of a new species, as the African specimen has nothing in its characteristics which could enable any one to distinguish it from the Indian species.

Scalaria turbinata, Forbes. Transact. Geol. Soc. vii. p. 127, pl. xii. fig. 18.
Scalaria ornata, Baily.
Mr. Baily 's specimen not only agrees with the Indian Scalaria in the description and figure, but more so even upon a careful examina-
