This remarkably variable species is but poorly figured in Dunker s work The illustration above cited represents tbe spire much more obtuse at the apex than is usual. The operculum is purpuroid The following measurements will show how variable is the size ol different specimens:- Length 13 millims., diam. 5j „ 11 „ „ 5 ,, 10 „ „ 4 1 li 4 ,, 1 1 2 >> " 67. NASSA (ALECTRION) GLANS, Linn. Nassa glans, Kiener, Coq. Viv. pi. 15. f. 52; Reeve, Con. Icon. fig. 5. Hab. Station 7. Philippine Islands and Australia are other localities. . . The operculum of the single specimen of this species is of a bright vinous red colour, of an elongate subtrigonal form, the angles being rounded and the margins simple. The shell itself differs from the ordinary form of the species in having a less elongated spire, and the body-whorl less inflated and encircled with only eight red lines instead of nine. 68.

The costa? in the Japanese specimen are fewer than in the originally described examples. In the latter the penultimate whorl has about 32 upon it, whilst the same volution in the former has but 22 to 24; in one specimen, however, there is the normal number. The largest example is 28 millims. long and 12 wide. The operculum (fig. 45a) is rather elongate, brown, serrated along the outer margin and also on the inner edge for a short distance from the nucleus. 69. NASSA (ZEUXIS) VARICIFERA, A. Adams, var.
