''Conus circumcisus'', common names the circumcision cone or the auger cone, the borer shell, or the leader cone, is a species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails and their allies.〔 Like all species within the genus ''Conus'', these snails are predatory and venomous. They are capable of "stinging" humans, therefore live ones should be handled carefully or not at all. ==Description== The thin shell is striated throughout. The color of the shell is yellowish or violaceous white, clouded.with chestnut, with distant revolving series of chestnut spots and short lines, most conspicuous on two irregular lighter bands.〔George Washington Tryon, Manual of Conchology, vol. VI, p. 81 (described as ''Conus circumcisus'')〕 The shell of ''Conus brazieri'' G. B. Sowerby III, 1881 is rather solid, with revolving striae throughout. Its color is whitish, tinged with pale rose-pink, with two broad, light yellowish brown bands, sprinkled here and there with a few very minute brown spots. The spire is conspicuously marked with dark brown blotches.〔George Washington Tryon, Manual of Conchology, vol. VI, p. 81 (described as ''Conus brazieri'')〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Conus circumcisus」の詳細全文を読む スポンサード リンク
