(Hig. 5 p320r.) 
Shell imperforate, turritely fusiform, whitish flesh colour; 
remaining whorls 5, sculptured with rather fine, erect and closely- 
set, transverse costulae, the terminations of which are bent for- 
ward in a hook-like manner in the immediate super-sutural region 
and of which there are seventeen on the last whorl, the interstices 
being quite smooth; suture impressed, crenellated by the hook- 
like terminations of the transverse costulae; columella descending 
in a slightly angular curve; aperture oblique, oval. 
Alt. 7:75, diam. maj. 4°5 mm. 
Aperture: alt. 3, diam. 2 mm.

Journal of Malacology, XII, 1905, p. 6 [as Pyramidella (Mor- 
mula) |. 
Channel off Barhampur Id., 6-9 ft.; Nalbano and channel 
S.E. of Nalbano, 4-8 ft. (a single deformed specimen): E. side 
of Rambha Bay, I 42 ft.; southwards from Mahosa, 5-9 ft.; 
main channel W. of Satpara Id., 3-8 ft.; Serua Nadi, 5-9 ft.; 
Mahosa, southwards towards sandhills, 4-8 ft. 
This appears to be a very variable species in sculpture, 
convexity of the whorls and size. Specimens differing in all these 
characters merge into one another but perhaps a single tapering 
specimen, which the author was at first inclined to regard as 
distinct, from ‘‘ Breakfast Island midway between Ganta Sila 
and Chiriya Island South Point (5-6 ft.)’’, may be especially men- 
tioned, the dimensions of this individual being: 
Alt. 8°75, diam. maj. 2°75, diam. min, 2°5 mm. 
Aperture: alt. 2, diam. I mm.
