Show 312 MR. A. ADAMS ON NEW JAPAN SHELLS. [Mar. 14, vertice submamillato ; anfractibus 4|, planiusculis, longitudinaliter oblique strigillatis, anfractu ultimo magno, superne inferne transversim striato, striis subdistantibus, ; apertura acuminato-ovata ; labio arcuato, incrassato, antice subplanato. Hab. Kino-O-Sima. Genus PUTILLA, A. Ad. Testa turbinato-conoidalis, rimata, solida ; apertura subquadrato-orbiculari; labio rectiusculo, incrassato, antice subeffuso, dilatato. Founded on a little, solid, robust, subpellucid shell, which will neither be affiliated to Eulima nor any other recognized form. PUTILLA LUCIDA, A. Ad. (Pl. XIX. fig. 25.) P. testa Candida, leevi, glabra, sublucida, rimato-umbilicata, solida; anfractibus quatuor, convexis ; apertura ut supra. Hab. Gotto Islands : 54 fathoms. FOSSARINA PICTA, A. Ad. (Pl. XIX. fig. 26.) F. testa turbinata, depressa, late umbilicata; spira parva; 4, convexis, spiraliter liratis, liris simplicibus, lutescente, maculis irregularibus atro-purpureis variegata ; anfractu ultimo magno, ad peripheriam rotundato; apertura orbiculata, patula ; labio arcuato, acuto ; labro postice dilatato, ascendente. Diam. 3, alt. 2| mill. Llab. Tanabe ; Kino-O-Sima : on the shore. A species very similar in form to the type, F. patula, Ad. & Ang., from Port Jackson; but the lirae are equal and simple, the aperture is nearly circular, and the outline of the shell is more orbicular. It is marked with irregular purple-black radiating blotches, and the umbilical region is generally pale yellow. AMATHINA NOBILIS, A. Ad. (Pl. XIX. fig. 27.) A. testa capuliformi, solida, Candida ; apice mediano, dextrorsum inclinato, involuto, acuto; extus valde bicarinata; apertura subcirculari, ampla, margine posteriore dilatato. Diam. maj. 25, min. 22, alt. 17 mill. Hab. Cape Notoro, Island of Saghalien. • I found this very remarkable shell cast up on the shore after a gale, in company with Pilidium commodum, Middendorff, Velutina coriacea, Pallas, and many other fine molluscous exuviae. There are now three species of this group-A. tricarinata, Chem., A. bicarinata, Pease, and A; nobilis. MACROCHISMA SINENSIS, A. Ad. (Pl. XIX. fig. 28.) Animal very large and elongated, bearing the shell in a sloping |
