identity may be proved in time. I never had occasion to observe any columellar plaits 
on the Gosau-species, but they may have been only obliterate and not visible from the 
want of a satisfactory state of preservation. In the present Indian species, the folds. 
are so faint, that in scarcely one out of ten cases are they distinctly marked, and as 
all the rest regarding form and ornamentation of shell agrees well with the above- 
mentioned species, it is certainly desirable to draw attention to this point in any 
future examination. I am at present in doubt whether such faint plaits do not 
exist in the Gosau species described by Zekeli (ibid. p. 74, Pl. 18, Fig. 8) as Voluta 
torosa and transferred by me to Fusus (Sitzb. 1865, LIT. p. 83); if this be the case, all the 
three forms must be united under one name. It is even questionable whether the 
Fasciolaria torquilla, Zek. sp. (Cancellaria id. Zekeli, loc. cit. p. 81, Pl. 14, Fig. 11) 
could be kept as distinct ; but it has the folds much stronger. The transverse ribs 
of the present species become above towards the suture of each whorl nearly 
obsolete, which is specially due to a greater or lesser contraction of the whorls. The 
spiral strize are originally pretty strong, numerous and very close ; they are crossed by 
numerous fine lamellar strive of growth, which occasionally produce a fine granulation 
on the former. 
The outer lip is sharp, and on the margin internally grooved; the inner lip 
always leaves a small fissure visible near the termination of the columella; close to 
the posterior end it is only slightly toothed.

The whorls, usually about six in number, are regularly convex, broadest in the 
middle, the last considerably longer than the spire. The surface is covered with 
numerous spiral strize, and transversal ribs. Of the latter there are from 16 to 20 in 
one whorl, nearly straight and equal in their entire extent, not tuberculated at 
the suture, as in as. assimilis, nu. sp. While the spiral strize increase in strength with 
age, the transverse ribs disappear gradually altogether, being at first less numerous. 
The canal is at its termination slightly bent inwards, and the columella exhibits
