Retrieved through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=594443 on 2013-04-14〕 ==Description== The height of the shell is 5 mm. The small shell is turbinate, depressed, orbicular, and rather solid. It is sordid white and clouded red. It is irregularly keeled all over, with the interstices finely, irregularly, neatly obliquely lirate, and peculiarly punctate. The larger keels are smooth or obsoletely granular. The five whorls are convex, the last obtusely angular. The base of the shell is flat or slightly convex and spirally lirate with equal lirae and spotted brown. The interstices are transversely neatly striate. The aperture is subquadrate. The outer lip is closely dentate. The throat is conspicuously lirate. The columella is obtusely unidentate. The margin of the umbilicus is regularly tuberculate with rounded granular tubercles.〔(Tryon (1889), Manual of Conchology XI, Academy of Natural Sciences, Philadelphia ) (described as ''Trochus angeli'')〕 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「Brookula angeli」の詳細全文を読む スポンサード リンク
