OF SOUTHERN INDIA. 359 
covered with spiral ridges, each measuring about one mm. in thickness and separ- 
ated by equally broad furrows. There is no distinct granulation to be observed on 
the ridges, but they appear to be a little rough. The umbilicus is large, and the 
aperture nearly quadrangular. 
This species in general form and ornamentation very much resembles Astralium 
muricatum, Zek. sp., from the Gosau-deposits of the Alps (Sitz., Akad., Wien, 1865, 
LIT, p. 589, and Abhandlungen Geol. Reichs-Anst., 1852, vol. I, pt. I, p. 57, pl. 10, 
figs. 7, 10, 11), but it is distinguished by the want of distinct tubercles or spines on 
the spiral ridges, which are also more numerous than in the European form, 
Locality.—Moraviatoor, in brownish, calcareous sandstone; only a few, not 
perfectly preserved specimens have as yet been obtained. 
Formation.—Ootatoor group.

A very distinct, broadly conical, thick shell, which has each of the whorls 
ornamented with four sharp and slightly undulating ridges. Two of these are 
placed at the respective anterior and posterior margins of the whorls, and two in the 
middle; they are separated by three equally broad and deep furrows. The surface 
of the shell appears to be otherwise smooth. The basis of the last volution is flat, 
not umbilicated, but the columella and a neighbouring portion of the inner lip are 
strongly thickened and callous; the aperture is quadrangular, much broader than 
high. 
I am not acquainted with any cretaceous species which could be compared 
with this remarkable shell. The ridges show only a very slight undulation, but no 
spines or tubercles, still I do not think that the species could belong to any other 
known genus. The general form of the shell, the thickened solid columella and 
the strong inner lip perfectly agree with species of Calear. 
Locality —Moraviatoor, in brownish, calcareous sandstone: only the figured 
specimen, which is in many respects rather imperfect, has as yet been found. 
Formation.—Ootatoor group.
