A handsome fusiform shell, whorls probably ten, the apical 
being absent in our specimens, whorls slightly angled and 
ventricose, ribs and transverse liree of about equal size, the former 
being small and feeble; at the sutures and round the middle 
of the last whorl are ochre bands. Outer lip much thickened 
and expanded, sinus spoon-shaped, wide and broad, outer lip 
finely denticled within, columella also denticulate. (@jcaupos, 
treasure).

Long., 4°50, Lat. 2 mull. 
A pure white, curtly pyramidal species, the surface not 
shining. Whorls six, turreted, angled at the suture, ventricose, 
longitudinally thickly ribbed, transversely ornamented with few 
lirations. In the middle of the upper whorl and doubly-ranked 
in the last whorl, are transverse regular deep pittings, squarrose, 
profound, between the ribs, which suggest the trivial name. 
The mouth is narrowly oblique, outer lip thickened, furnished 
with four strong denticles, the columellar teeth are more obscure 
and feeble. Only one specimen, and that slightly worn ; but 
the characters are so remarkable as to excuse description from 
such scanty material. (@vpidwros, furnished with windows or 
doors.)
