Oval-conic, strong, sliiniug, indistinctly zoned with olive and 

 pale fulvous (more rarely and chiefly when worn or young, with 

 whitish and chestnut brown), the darker colouring, chiefly 

 present on the body-whorl, in tliree bands, of which the middle 

 one is moderately broad, and most conspicuous, the infrasutural 

 one is, at the least, equally as broad, but less defined, and 

 only separated from the former by a pale narrow fillet, whilst 

 the basal is hardly visible till the shell is held up to the 

 light : the penult whorl olivaceous with a paler spiral fillet ; the 

 rest of the turns are more or less light coloured. A narrow 

 retuse or indented area runs beneath the fine suture ; and is 

 studded at the top with small isolated nodules that are not in 

 the same line with the longitudinal ribs with which the re- 

 mainder of the surface is adorned. These last, generally about 

 fourteen or fifteen on each of the larger turns, are usually some- 

 what flexuous and oblique upon the body, and much narrower 

 than their intervals ; the reverse holds good upon the apical 

 coils. Two strongly incised spiral lines (occasionally a third 

 obscure one above them) wind round the base of the body-whorl, 

 which, as well as the principal turns of the spire, is otherwise free 

 from spiral sculpture. The spire, which tapers to a very fine 

 point, is composed of seven or eight volutions, the lower one of 

 which (whose breadth to its length is usually as five to three) is 

 about equal in height to the rest united. They arc of rather 

 fast longitudinal increase, not much rounded ; and, at least, the 

 lower ones, subangulatcd above. The body, which fills about 

 four-sevenths of the dorsal length, is moderately broad, but not 

 ventricose, the surface being merely convex ; the basal attenua- 

 tion is inconsiderable, and the basal declination very gradual : 

 the very short beak, whose spiral sulci are few in number, is not
