426 CRETACEOUS GASTROPODA 
The only species which bears some resemblance to our fossil is Cinulia catenata, 
Tate (Quart. Journ. Geol. Soc., Lond., 1865, XXI, p. 38, pl. 3, fig. 4) from the 
Upper Chalk of Ireland. The anterior fold of the inner lip of the Ivish fossil 
corresponds with that of South India, but the posterior portion of the lip has not 
been observed in the former. 
Locality —The single but perfect specimen was found in the soft, glaukonitic 
sandstone near Olapaudy with Fasciol. assimilis, Stol., and others. 
Formation.—Trichinopoly group, but close to the boundary of the Arrialoor. 
2. Evuprycua Larvara, Sfoliczka, Pl. XXVI, Fig. 6. 
Eupt. testa ovata, subdepressa, in superficie sublevigata, spiraliter lineis im- 
pressis obsoletis notata, spira brevissima, obtusiuscula, circiter septimam partem 
totius aititudinis occupante ; apertura perangusta, postice subcanaliculata; labio ad 
medium valde incrassato atque producto, deinde profunde insinuato, antice plica lata, 
in medio furcata terminanti; labro extus varicoso, intus calloso, antice tenwiori ac 
late insinuato, canali angustissimo.

Shell ovate, somewhat depressed from front to back, almost smooth, sometimes 
marked with few obsolete spiral lines; spire very short; aperture very narrow, 
posteriorly canaliculated ; inner lip forming about the middle a thick callous plate 
obliquely projecting into the aperture, then deeply insinuated laterally, and ante- 
riorly terminating with a very broad, flat, in the middle grooved, fold, in front 
of which there is a very narrow channel; outer lip internally and externally 
thickened and anteriorly insinuated. 
The more elongated oval form, almost smooth surface, shortness of the spire, 
and median thickening of the imner lip easily distinguish this from both the 
previous and the following species. 
Locality.—Comarapolliam, in light coloured or ferruginous sandstone ; rare. 
Formation.—Arrialoor group. 
8. EUPTYCHA OVIFORMIS, Forbes, sp., Pl. XX VI, Fig. 7. 
1846. Nerita oviformis, Forbes, Trans. Geol. Soc., Lond., VII, p. 122, Pl. XII, Fig. 13. 
Eupt. testa ovato-globosa, in superficie striis spiralibus impressis notata, spira 
brevi, obtusa; apertura angustissima postice acute canaliculata; labio postice bitu- 
berculato, ad medium late producto, deinde profunde insinuato atque intus ad 
marginem wnidentato, antice plica crassa, lata, in medio furcata terminanti ; canali 
angusto, haud distincto ; labro extus paulum, intus multum, incrassato, antice insinuato.

The globose form, obtuse spire, distinct spiral striation, the posterior and 
anterior small tuberculations of the inner lip easily distinguish this species from
