Journal of molluscan studies
PLATE XXI. THE shells forming the subject of the present article were for the most part received from Dr. Cox, together with the specimens of Chloritis treated of in the previous paper. PAPUINA coiir-LANATA, n.sp. PL XXI, Fig. 12 . Shell imperforate, trochoidal, the earlier whorls bluish white, the penultimate becoming yellowish brown, the last dark brown above, yellowish brown below, finely distinctly striated and with excessively fine and close spirals above, and distant shallow spiral
... allow spiral furrows below. Spire conical, apex exserted, suture shallow, margined. "Whorls 6, convex, increasing regularly, the last dilated towards the mouth, convex above, slightly flattened at the suture, bluntly keeled at the periphery, slightly compressed below and excavated at the umbilical region, very shortly descending below the periphery in front. Aperture subelliptical, very oblique, margins convergent; peristomo white, thickened, expanded, and refloxed; upper margin slightly curved, outer rounded, columellar flattened, adnato to the parietal wall. Diam. maj. 26*5, min. 20-5 mm.; alt. 18 mm. JTab.-Probably New Ireland (Mus. Cuming). Type in the British Museum. A single specimen from Now Ireland sent by Dr. Cox was found to have its counterpart in the Cuming Collection in the British Museum without habitat. The new species is allied to P. vexillaris, but is readily distinguished by its broader and more flattened base, the more pronounced peripheral keel, the more expanded peristome and dilated aperture, and by the absence of the obliquely descending wrinkles above the periphery.
