this species are procured is, that the posterior constriction of the whorls along the 
suture may be connected with, and dependent on a slight insinuation of the outer lip, 
and in such a case the species would have to be transferred to angelia or Clathurella 
(Defrancia, Millet). I have not, however, been able to detect in our present speci- 
mens any curvation of the striz of growth, which would indicate such a notch 
on the aperture. The spiral strize are fine and cover the entire surface of the shell; 
their slight undulations are caused by the strive of growth. 
Buccinum supracretaceum, Binkhorst, quoted above, is the nearest and among 
cretaceous species the only ally of our Indian fossil. It differs, according to 
Binkhorst’s figure, by the more uniform convexity of the whorls and by the 
transverse ribs being almost perpendicular to the direction of the sutural line. 
Localities.—Vaitagoody and N. of Karapaudy, in Trichinopoly district. Only 
two specimens have as yet been examined ; neither of them has the outer lip, nor the 
anterior extremity with the termination of the canal, perfectly preserved. 
Hormation.—Arrialoor group. 
XXXVI. PSEUDOLIVA, Swainson, 1840. 
1. PsEUDOLIVA suBCosTATA, Stoliczka. Pl. XII, Fig. 2. 
Pseudol. testa ovata ; spira ultimo anfractu breviore ; anfractibus quinis, primis 
duobus levigatis, ceteris transversim multicostatis ; costis circiter 16 in uno circuitu, 
parum obliquis, in ultimo anfractu infra medium evanescentibus ; parte anteriori 
ultini anfractus usque ad sulcum medianum spiraliter striata; sutura canaliculata 8 
margine posteriori anfractuum terminatione costarum coronato ; apertura ovali, 
postice acuta; labio levi, calloso, arcuato. 
Spiral angle 65°; sutural angle, 10°. 
This pretty little shell is, although not perfectly preserved, well characterized 
by the numerous transverse ribs, which on the last whorl become obsolete about the 
middle of its height; they are slightly curved, and on the deeply canaliculated 
suture somewhat produced into sharpened points. Below the principal furrow, 
which is characteristic for the genus Pseudoliva, the anterior portion of the last 
whorl is finely, spirally striated, the rest of the surface being apparently smooth. 
The posterior part of the inner lip is thickened, and so far as visible internally quite 
smooth; the canal or rather the emargination of the anterior extremity is indicated 
by a slight swelling extending from the inner margin in a curve parallel to the 
principal furrow ; the termination of the canal has not been, however, as yet observed. 
Locatlity—Ninnyoor ; occurring in a white arenaceous limestone; only the 
figured specimen has as yet been procured. 
Formation.—Arrialoor group.
