Anotace knihy

Excerpt from The Nautilus, Vol. 29: A Monthly Journal Devoted to the Interests of Conchologists; May, 1915, to April, 1916 I have recently received a series of Blanfordias, representing a new species, from Prof. Seitaro Goto of the Zoological Institute of the Science College, Imperial University of Tokyo. Professor Goto writes as follows: "I am interested in these snails as the intermediate hosts of the Japanese blood fluke, whose life-history a former student of mine has succeeded in making out. He has already published a short preliminary paper on the subject and I hope that he may be able to quote your authority in his full paper in regard to the specific identity of the snails. The locality of these specimens is Sakai, Saga Prefecture (Kyushu)." Blanfordia Nosophora (Robson). The shell is perforate, turrited, solid, of a russet color, the worn summit pink or dark vinaceous. The surface is glossy, faintly marked with growth-strić. The early whorls are wanting in the adult stage, 5 to 7 whorls remaining. These are strongly convex, united by a deep suture. The last whorl swells out to form a rounded ridge or varix behind the peristome. The aperture is vertical, ovate, somewhat diagonal; deep within it is of a vinaceous color, then yellowish in a band under the varix, finally olive at the edge of the lip. The peristome expands and is narrowly recurved at the edge, and a transparent callus connects the outer and inner margins.
