Prosopeas anceyi Pilsbry, 1906
“This species is especially remarkable for its subulate, greatly lengthened form. The name proposed by Mr. Ancey is preoccupied for a Philippine species.” (Pilsbry, 1906)
Pilsbry (1906) original descriptions on Prosopeas anceyi – “Shell fragile, subpellucid, glossy, subulate, very narrowly and almost vertically subrimate; under a lens, sculptured with close and arcuate growth-striaa. Spire long, gradually tapering, the apex obtuse, quite large and smooth. Whorls 10, plano-convex, rather rapidly increasing, separated by an impressed, very minutely and regularly crenulated suture. Last whorl cylindric-oblong, tapering basally, hardly ascending. Aperture vertical, oblong, narrowed above and below, the base receding. Columella slightly arcuate, a little thickened, reaching to the base of the aperture, scarcely truncated. Columellar margin lengthened and narrowly dilated above the rimation. Lip acute, rounded and produced in front. Color pale grayish-corneous.”
Prosopeas anceyi – “Length 15.25, diam. 3.25, aperture 4x2 mm.” (Pilsbry, 1906)
