5A CRETACEOUS GASTROPODA 
Vol. LII, p. 64,) from the Gosau deposits of the Eastern Alps is, no doubt, the 
nearest ally to our Indian form, and, so far as I know the single specimen of the 
former, it differs by being anteriorly slender and more produced. Better materials, 
when procured on both sides, will make a closer comparison of these two forms 
unavoidable. 
Locality —Near Moraviatoor in Trichinopoly district; only two specimens are 
as yet known. 
Formation.—Ootatoor group.

Oyp. testa pyriformi, globosa, postice subobtusa, antice breviter attenuata, vie 
emarginata, levi, polita, anfractibus occultis; apertura subangusta, antice dilatata, 
utrinque denticulata; labro inflexo, crasso, rotundato, postice extenso, antice imtus 
insinuato, tenwissimo; labio calloso, antice sinuato atque plica elevata terminante, 
lateraliter compresso et acuto. 
The shell is distinguished by its strong globosity, being anteriorly not much 
produced. The whorls are perfectly concealed and the place of the spire is indi- 
cated by a slight impression only; the surface is smooth and polished. The 
aperture is slightly curved, narrow above and nearly of double the width near the 
anterior extremity, where it is slightly notched, while the posterior channel turns 
quite upwards towards the dorsal convexity, exactly asin living species of Lawponia. 
The outer lip is considerably thickened, posteriorly somewhat expanded, inflexed 
in its entire length and internally denticulated; near the anterior canal, where the 
aperture widens, the outer lip and equally the inner are much thinner, laterally 
compressed and forming more or less sharp ridges. The dentition of the inner lip is 
somewhat stronger near the anterior termination than in the middle and posteriorly ; 
at the anterior canal the lip terminates with a strong fold, which can be traced all the 
way inside along the base of the spire; the next tooth is also somewhat longer, and 
both these are separated by a deeper insinuation from the other teeth. These 
characters also quite agree with those of living Cyprea. Gray regarded the 
inner fold along the anterior canal of greater importance than seems necessary, 
and established his sub-genus Naria, which, if based upon that peculiarity alone, 
must again be abandoned. 
Specimens which are devoid of the shell-surface are more globular, because 
the anterior portion, being very thin and consisting nearly all of shell, is lost in 
the cast. We have figured (Pl. IV, Fig. 3) one of those casts, which also exhibits 
the impressions of the marginal dentition in the aperture very clearly. A similar
