principal constriction of the whorls, as is also distinctly seen in his figures; but 
while there are usually two impressed lines in this suleation, close to each other, 
there is often a third line seen above it, and it could only have been this to which 
Prof. Forbes refers as the second sulcation. On the upper volutions there is gene- 
rally nothing seen of the impressed lines, the deeper sulcation only remaining 
visible. 
The posterior portion of the inner lip is very much thickened, smooth, and 
separated from the equally thick outer lip by a narrow channel. The columellar 
portion of the lip exhibits two strong folds, the anterior of which is more oblique ; 
they were not visible in Prof. Forbes’ specimen, although he suspected their presence, 
and in that was undoubtedly more correct than D’Orbigny, who might rather have 
called the species a Buccinum, but not a Fusus, to which it has barely a resemblance, 
even in an imperfect state. The anterior emargination of the aperture is externally 
indicated by two sharp ridges, which mark its former limits, the lower one being 
more rounded. 
Locality —Comarapolliam, N. of Arrialoor; only a few specimens have as yet 
been found. Prof. Forbes’ specimens are said to be from Pondicherry. 
Formation.—Arrialoor group.

This species is intermediate between C. breviplicata and Camdeo ; it has the 
habitus of ribs and of the whorls of the first, but the great number of ribs and the 
elongated form of the latter. There are only five volutions present, and the two 
uppermost are smooth; along the suture there is only one broad sulcation, but this 
is placed much nearer to the suture than in Hue. breviplicata, as will be better seen 
by a comparison of the respective figures. The transverse ribs amount on the last 
whorl to 30, and they become obsolete, after they have passed the middle of the 
whorl, where the spiral striation begins. The upper ridge, indicating and bounding 
the anterior notch exteriorly, is especially strong and sharp. The inner lip is 
thickened posteriorly, and has in front two oblique folds, being comparatively much 
thinner than in Hw. breviplicata. 
Locality. —Comarapolliam, where a few specimens have been procured with 
the two other species of Huclia. 
Hormation—Arrialoor group.
