S. Fish Com., 1880. Fisr. 1. Mangilia cerina Verrill. Pkurotoma cerinum Kurtz and Stimpson, Proc. Boston Soc. Nat. Hist., iv, p. 115, 1851 ; Stimpson, Shells of New England, p. 49, pi. 2, fig. 2, 1851. Mcingelia cerina YcrnW, Amer. Journ. Sci., iii, p. 210, 1872; Verrill, Rep. Invert. Anim. Vineyard Sd., in Rep. U. S. Fish Cora., i, p. 637, description, 432, (autli. ed. p. 343), 1874. This shell is easily distinguished by its slender form, with the whorls angularly shoiddered, and having a wide, concave, subsutural band. The ribs are few, angular, thick, obtuse. The whole surface is covered by fine, spiral lines, minutely decussated by the lines of growth. Lip with a well-marked sinus below the suture, near the shoulder. Niicleus with the apical whorl regular, smooth, and very small, dei)ressod ; the second whorl is crossed by fine riblets, then two spiral gi'ooves ap- pear around the middle; on tlie third whorl there are three spiral grooves, and the riblets are more prominent, producing a decussated sculpture. On the fourth whorl the normal sculpture appears. This species was erroneously omitted from Binney's edition of Gould's Invertebrata. It is found near Newport, R. L,
