Schistoloma perakensis (Fulton, xxxx)
Junior synonym of Schistoloma sectilabrum (Gould, 1844)
Fulton (1903) original descriptions on Coptocheilus perakensis – “Shell narrowly perforate, moderately solid, reddish-brown, spire elongately-conic, obliquely striated, last two whorls margined at the suture, whorls 7½, slightly convex, aperture circular, brown within; peristome sub-duplicate, expanded, whitish, margins connected by a raised callus, somewhat angular at upper columellar portion; operculum normal. C. perakensis differs from sectilabrum, Gld., in having no notch or sinus on its peristome, which is thinner, and also by its less convex whorls; from anostoma, Bens., it is distinguished by its smaller aperture, less convex whorls, and its more elongated form. The name Coptocheilus being said to be preoccupied, Kobelt has proposed the name of Schistoloma for this group.”
Coptocheilus perakensis – “Maj. diam. (including peristome) 11, long. 23 millim.” (Fulton, 1903)
