302 CRETACEOUS GASTROPODA 
narrowly but deeply canaliculated. The surface is smooth, occasionally with some 
traces of a fine spiral punctuation or striation, as is common among all Nazrcrpz. 
The aperture is semilunar, slightly oblique, much narrower posteriorly than ante- 
riorly ; the inner lip thin and anteriorly furrowed, exposing a slight fissure. 
The height of the spire, as compared with that of the aperture, the large 
number of volutions and the narrow but deep sutural canaliculation, easily dis- 
tinguish this species from similar forms, like Natica (Amauropsis ?) Clementina, 
D’Orb., Littorina (Huspira) pungens, Sow., and others. Geinitz (Quadersandst., 
etc., 1849-50, p. 128,) unites under the name Nat. vulgaris, Reuss, a very large 
number of apparently different species, some of which very much resemble our Indian 
fossil. We would also draw attention to Awricula spirata and Nat. lamellosa, 
Romer (Kreide. pl. 11, fig. 4, and pl. 12, fig. 18), two apparently identical species 
which, as regards the form and small height of the volutions, are remarkably like our 
Eusp. pagoda, but Rémer’s descriptions and figures, referring on the one hand to a 
doubtful thickening of the outer lip and on the other to strong lamellar, transverse 
strize, do not at the present permit an identification. <A similar doubt exists with 
regard to the identity of our species with Nat. exaltata, Goldf. (Petr. Ger. III, 
p. 119, pl. 199, fig. 13). 
Locality.—Between Andoor and Veraghoor, in light coloured sandstone; not 
common. 
Formation.—Arrialoor group. Prof. Forbes’ specimens are also from the upper 
beds near Pondicherry.

This species is distinguished by its regularly conical and pointed spire, being 
composed of numerous almost plain volutions, separated by a shallow suture. 
The last whorl is much inflated and globose, the surface being marked with oblique 
strie of growth, although otherwise smooth, the aperture ovate with a thin inner 
lip, and the columella distinctly excavated. The species in form resembles Litto- 
rina (Buspira) pungens, Sow. (Trans. Geol. Soc., Lond., 1836, IV, p. 348, pl. 18, 
fig. 5), but this last one has the whorls near the sutures canaliculated, as can be 
observed on typical specimens from the Blackdown Greensand, though Sowerby’s 
figure is not very clear on this point. 
Locality.—East of Anapaudy ; only the figured specimen has as yet been found. 
Formation.—Trichinopoly group, but near the boundary of the Arrialoor group,
