It is not without doubt that we refer an imperfect specimen of a Twurritella 
to this species, which is so common in the upper ecretaceous beds of Northern 
Germany. The character of the ornamentation is in general the same, as noted by 
Goldfuss and Romer. There are six spiral and granulated striz on each whorl, 
the one on the posterior or upper margin being the strongest, and the two anterior 
being placed closer to each other, than the one immediately below the strong keel. 
The other strize are placed still nearer to the anterior suture of the whorls and are 
usually not granulated. The entire surface of the shell is besides very minutely 
striated. 
The differences, which we have to note between our fossil and the European 
species, are the whorls being slightly higher in proportion to their width, and the 
fourth of the striz from the top being stronger, than any of the two others on 
each side, above and below it. In Goldfuss’ figure a similar fact seems to be indi- 
cated in the third ridge from above, and it is not quite impossible that such a 
slight variation may occur in the ornamentation of one and the same species. We 
do not wish to be positive as to our identification of such imperfect specimens, but 
we desire to draw the attention of any subsequent explorer in South India to this 
very interesting fossil, for if it proves to be identical, it is more important than a 
dozen of other new species. 
Our species can also be compared with Sowerby’s Z. granulata from Black- 
down, but in this the spiral keels are usually more closely arranged. 
Locality.—W. of Odium, in a calcareous sandstone; apparently very rare. 
Formation.—Ootatoor group.
