Spire high and tapering; shell subpyriform; smooth, pale yellowish, sprinkled with fulvous; body-wreath with six bands, the three uppermost linear, and composed of alternate white and chesnut-coloured dots, the three lower of two broad castaneous bands, marked with subsaggitate oval spots, and an intermediate narrow belt of alternate brown and white dots. * * * * * This shell, like the former, (fig. I) constituted part of the Leverian collection of exotic shells. Its length is an inch and half, its greatest breadth exceeding five-eighths of an inch. Notwithstanding the inferiority of its size, this very elegant and curious shell is not less interesting than the preceding. The general tints in both are nearly the same, but in the present shell are rather deeper, the dots of fulvous brighter and more thickly sprinkled, and the bands more numerous. Like the former shell it has two broad bands of brown, checquered with subovate spots of white, and an intermediate dotted line, but these are placed rather nearer towards the narrower end of the shell, and the intervening space between the spire and the larger band, encompassed or girt round with two other linear bands, composed of white and brown dots, besides another still more conspicuous, and composed of larger spots along the base or body-wreath, contiguous to the spire or turban. This little shell may be considered as affording an excellent type of one of the rarer kinds of Conus Ammiralis, the variety denominated the Six-banded high-spired Admiral Cone. During a period of some years that have now elapsed since the dispersion of that collection, no other example of this variety has occurred to our observation more perfect and characteristic in all its markings. FIGURE III. CONUS AMMIRALIS var CEDO NULLI α. OLIVE-BANDED NONPAREIL CONE. Spire high and tapering; marbled white, fulvous, and dusky; body-wreath with three subolivaceous bands, the broadest towards the spire, with four belts of whitish dots; the two others towards the narrow end each with a single row of dots. * * * * *
