184 CRETACEOUS GASTROPODA 
as identical with the previous species (vide Jahrb. Geol. Reichs-Anst. 1863, vol. XITT, 
p. 50). Mister described his N. ceeta from the Gosau, but I never met with 
it, nor have I seen anywhere a specimen which had been collected in these Alpine 
cretaceous deposits, although there is no reason to assign, why it ought not to 
occur, for several of the fossils from Transylvania and the Alps are identical. The 
species has been lately found in the cretaceous deposits of Lowenburg in Germany. 
Our South Indian specimens agree perfectly with those from Transylvania, which 
T had compared. 
In my paper, quoted above, I have also drawn attention to the similarity of 
N. Conimbrica, which had been described by Sharpe from Portugal, What 
Schafheeutl (Leth. Geog. Siid-Bayerns 1863, p. 389), Pl. LXV d, Fig. 2) describes 
and figures as V. cincta, Miwmst., along with most of the other determinations of 
this author, must first be a little better ascertained before it be admitted. 
Locality—From a conglomeratic coarse sandstone of the wlelegH oat of 
Parully in the Trichinopoly District; rare. 
Formation.—Ootatoor group. 
2, NeERINEA BLANFORDIANA, Sfoliczka, Pl. XIV, Figs. 4-6. 
Ner. testa turrita; anfractibus medio excavatis levigatisque, marge anteriori 
semper tumescente atque tuberculato, posteriori ad fasciam suturalem interdunt levi- 
gato, interdum sub-tuberculato ; columella, labio atque labro biplicatis, plicis anteriori- 
bus semper crassioribus ; plica posteriori in labio sepe obsoleta. 
Spiral angle 20°—25°; sutural angle 3°—5°. 
Height of one whorl : its width (considered as 1: 00) v.. —0'30—0'°36 
The difference in the proportions of the whorl and the greater spiral angle 
distinguish this species easily from the N. incavata, even when the preservation of 
_ the specimens is not very good. The sutural band is always very narrow, sometimes 
scarcely traceable. The posterior margin of each whorl is either smooth (vide Fig. 4, 
a very much worn specimen from a coral limestone), or, where the surface of the 
shell is better preserved, ornamented with large tubercles; the middle portion is 
concave and smooth (vide Fig. 5); the lower margin always somewhat enlarged and 
tuberculated. The columella is solid, and has like the posterior portions of the inner 
and of the outer lip each two folds, the upper or posterior ones being in each case 
much thinner and becoming often obsolete near the aperture. 
This species resembles, as regards form and the changes in orn namentation, very 
much the Nerinea Buchii, Kefst. sp. from the Alpine Gosau formation (vide Abband, 
Geol. Reichs-Anst. Wien, 1852, Vol. I. pt. II, p. 34, and Sitzungsb. Akad. Wien, 
1865, Vol. LII, Revision, etc., p. 27). The European species differs by its usually 
hollow columella, even or much less concave whorls, and in having above the ‘anterior 
tuberculated margin of each whorl a deeply impressed line, interrupted by the pro- 
longation of each tubercle. This latter character is additional for NV. Buchii, and 
has not been, I believe, previously noticed.
