The shell has a regularly conic shape. It is flesh colored, with squarish maculations of chestnut brown, the latter occupy a zone extending from the periphery to the middle of the whorl, and are separated from each other by a space about equal to the width of the brown spots. On the base, the spiral cords are dotted with maculations of the same color. The are at least two nuclear whorls, apparently smooth. The postnuclear whorls are marked by spiral cords and axial riblets forming tubercles at their junction, thus lending the spiral cords a granulated appearance. Of these cords, 3 occur upon the first, 4 upon the second, 7 upon the third, 8 upon the fourth, and 10 upon the penultimate turn between the periphery and the summit. These spiral cords are separated on all but the body whorl by spaces about equal to the cords in width. On the last turn, however, the sulci are broader and the tuberculated cords are less regular than on the preceding turns. The sutures are slightly constricted. The periphery of the body whorl is decidedly angulated, and marked by a broad spiral cord. The base of the shell is short, slightly rounded, and marked by 14 somewhat flattened spiral cords of somewhat irregular width, increasing slightly in width from the periphery to the umbilical area. The spaces that separate them are also of somewhat irregular width, but in general are almost as wide as the cord. In addition to the spiral sculpture, the base is marked by numerous coarse lines of growth which cut the cords but do not render them tuberculated. The aperture is subcircular. The posterior angle is obtuse;. The outer lip is thin. The columella is strongly curved and reflected over the base as a slight callus at the umbilical area.〔( Paul Bartsch (1915) REPORT ON THE TURTON COLLECTION OF SOUTH AFRICAN MARINE MOLLUSKS, WITH ADDITIONAL NOTES ON OTHER SOUTH AFRICAN SHELLS CONTAINED IN THE UNITED STATES NATIONAL MUSEUM ) (described as ''Calliostoma africana'')〕 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「Calliostoma africanum」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.
