122 CRETACEOUS GASTROPODA 
from the eocene rocks of Alabama, in which species Conrad records three plaits 
on the inner lip. There is no difficulty as to confounding specimens of this 
Neptunea with Voiut. radula, Forbes, even when the plaits in the latter are not 
visible, as the spiral and transversal ribbings in this last named species are much 
more closely placed to each other and the square interspaces consequently much 
smaller. 
Localities—N. of Kunnanore and E. of Anapaudy, Serdamungalum, Kolako- 
nuttom, Shutanure, Andoor, E. of Veraghoor. The species is very common at the 
locality between the first two named places and not rare at the others. 
Formations.—Trichinopoly and (?) Arrialoor groups. To the last group only 
the Veraghoor locality refers, according to Mr. Blanford’s map. 
XXIV. FUSUS, Klein, 1753. 
1. Fusus VERTICILLATUS, Stoliczka. Pl. X, Fig. 20. 
Fus. testa elongata; anfractibus angulate-convexis, supra valde constrictis, 
transversim minutissime-, spiraliter crasse-striatis ; striis spiralibus alternatim fortio- 
vibus, una ad medium anfractuwm carinata, maxime elevata, obsolete tuberculata, 
secunda infra crassiore, atque ceteris in basi ultini anfractus sensim tenwioribus, supra 
carinam striis senis, alternatim fortioribus, ornatis; labro ad marginem tenwi, 
sulcato ; labio tenuissimo ; canali recto. 
Spiral angle 46°; sutural angle 11°. 
This species is well characterized by its ornamentation, the transverse strize 
of growth being only minute, although very distinct, while the spiral striation is 
much stronger. Each of the whorls is angulated in the middle by a sharp, 
obsoletely tuberculated carina, and above this there are, with the exception of the 
sutural margin, six striz, alternately stronger and thinner; the second of the 
striae below the carina is strongly marked on the last whorl and the following three 
become gradually thinner towards the anterior extremity, alternating regularly with 
others in strength. The strive of growth are only very slightly elevated in crossing 
the spiral striz and produce occasionally slight undulations of the latter. The inner 
lip is thin, the spiral striation being consequently partially apparent on the interior 
margin of the aperture; the canal quite straight; the outer lip sharp with an 
undulated margin, being slightly grooved internally. 
Locality —N. of Odium, in a brownish calcareous sandstone, very rare. 
Formation.—Ootatoor group.
