94 CRETACEOUS GASTROPODA 
2. VoLUTILITHES ACCUMULATA, Stoliczka. Pl. IX, Figs. 3 and 4. 
V’.. testa ovate-elongata, spira brevi, quartam partem totius altitudinis formante ; 
anfractibus senis seu septenis, accumulatis: primis duobus teretibus levigatis, ultimo 
supra inflato, antice valde attenuato, omninis convexis, transversim costatis, spiraliter 
minute striatis ; costis 16—18 in uno circuitu, ad suturas subangulatis ; columella ad 
medium triplicata: plicis obliquis, mediana crassissima. 
Spiral angle 60°—75°; sutural angle about 10°. 
The short spire, consisting of about five whorls only, these being strongly 
convex, the thickness of the posterior and the attenuated prolongation of the 
anterior portion of the last whorl, farther the numerous transverse ribs, varying 
from 16 to 18, and the three oblique columellar plaits, of which the middle is the 
strongest, can serve as the principal distinctions of this species from Vol. Casparini, 
D’Orb. and Vol. latisepta, n. sp. 
The embryonal whorls are as usual equally smooth, but they are not so high 
and aremuch more strongly convex than in /’. latisepta; the posterior portion of the 
inner lip appears to be also thicker in the present species. The surface is finely 
striated spirally and the striae become coarser with the size of the shell, or rather 
the impressed lines become more distant and somewhat deeper. The ribs on the 
upper whorls, next to the smooth embryonal ones, are more numerous, thin and 
more oblique, while the following are straight or even somewhat bent in the opposite 
direction (to the right) ; on the last whorl they are slightly flexuous and disappear 
soon below the middle of the height. 
T am not convinced that this species is not identical with Vol. d’ Orbignyana, 
Miiller (Petref. Aachner Kreide-form. 1851, IT, p. 40, Pl. 5, Fig. 27); in all respects 
it is most nearly related to it, and differs only by a shorter spire and greater number 
of columellar plaits. Miller says, that his specimen is “‘ perfectly preserved,” and 
with two columellar plaits only, while our specimens have distinctly three plaits, if 
the number may not be found to be increased by a fourth posterior one. 
Loculities.—N ear Olapaudy, Andoor, E. of Anapaudy, and 8. of Serdamungalum ; 
although not rare, no specimen has yet been found perfect with the outer lip. 
Formation.—Trichinopoly group.

1850. »  submuricata, D’Orb., Prod. II, p. 226; idem Guabb, ete. 
Vol. testa ovata, antice attenuata, postice apice acuta, inflata, spira brevi; an- 
fractibus paucis, tranversim atque spiraliter costulatis ; costulis primis Sortioribus, in 
ultimo anfractu antice evanescentibus ; ultimis acutis, supernis crassioribus, duabus 
prope suturam sulcis latioribus sejunctis, solum in anfractibus superioribus conspicws ; 
apertura angusta ; labio ad medium 4-5 plicato, plicis anterioribus Sortioribus. 
This species has a remarkably short spire with an angle of about 90 degrees, 
and the last whorl, which becomes anteriorly gradually thinner, measures nearly
