Its color pattern is creamy yellow with radial dark purple flammules dorsally and ventrally, grading off on the anterior side to crimson and rose pink. The separate tubercles have dark color giving the effect of dots. The rather small shell has a conical shape. It shows long, spirally arranged peripheral spines on all five whorls (about equal to width of shoulder). The whorls are flat-sided. The early whorls show, on the upper surface, five beaded spirals, between which on the later whorls are intercalated one or more much smaller beaded or simple threads. These are crossed obliquely by small, sharp, imbricated lamellae, visible only under a lens. At the periphery the thin keel is produced into narrow, guttered spines with two or three radial threads on each . The body whorl carries 10 to 15 triangular spines. The base is elegantly flammulate with dark purple, sculptured like the upper side, having one strong nodulous and seven or eight smaller spirals and the same imbricate minor sculpture. The peripheral keel should have, when intact, about 20 spines The shell lacks a sutural channel.The white columella has a very narrow basal, milk-white callus. The aperture is rounded. The outer lip leadis at the suture, which is laid on the prominent basal spiral before mentioned. The aperture is white except where the color markings show through the glaze. This species closely resembles ''Bolma guttata'' (A. Adams, 1863) but the spire is relatively shorter and has a less pronounced granular sculpture. The spines when perfect are about 4 mm. long. 〔 (Smithsonian miscellaneous collections v. 50 (1908) ) (described as ''Astraea persica'')〕 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「Bolma persica」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
