and very thick, as may be seen in our Fig. 1, Pl. XVI. Judging from the cast 
the anterior canal could have been only short and very narrow. 
Locality.—Near Veraghoor, in whitish sandstone; very rare. 
Formation.—Arrialoor group.

In some specimens the posterior or contracted portion of the whorls is often 
quite smooth, except a thickened margin, while in others there are two stronger and 
some finer spiral strize present. On the anterior or nearly perpendicular portion 
there are three or four striz with or without any intermediate ones. The trans- 
verse ribs terminate either on the middle angle of the whorls, or they are somewhat 
more prolonged posteriorly, but always much less marked. The aperture is consi- 
derably narrowed on both ends, and anteriorly produced ; the canal has not, however, 
been seen perfect, but it must have been only very short. ‘The inner lip is strongly 
callose, with a posterior tooth. 
As to form and ornamentation this species resembles Cerith. Stoddardi, Hislop, 
from the so called intertrappean beds near Rajamundry (Quar. Journ. Geol. Soc. 
Lond., XVI, p. 177, Pl. VIII, Fig. 35). It differs from that species chiefly by the 
unequal strength of the spiral strize and by having the transversal tubercles on the 
different volutions corresponding to each other in almost perpendicular lines, while 
in Cerith. Stoddardi the tubercles correspond to each other in very oblique lines 
and the spiral strize are more numerous and almost all of the same thickness. 
Localities —Garudamungalum, in a blueish, calcareous sandstone, and Kara- 
paudy, in whitish, soft sandstone; rare. 
Formations.—Trichinopoly and Arrialoor groups.
