RemarJcs. Altogether there are 15 Bpecies 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.

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 sjpecies belong to the lowest beds of the Indian 

 Cretaceous formation, to the Ootatoor group and the Yaludayur 

 group, and only one, A. Gardeni, belongs to a higher horizon, the 

 Arrialoor group, which resembles our white chalk.

This species is found in the same deposits. Shell perfectly smooth, 

 with scarcely visible lines of growth, and very thick. 

 Locality. Umtamfuna. Bed e.

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.

Mr. Baily, in his paper, looks upon this Turrifella 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 di- 

 stinguish it from the Indian species.

Mr. Baily 's specimen not only agrees with the Indian Scalaria in 

 the description and figure, but more so even upon a careful examina-
