Alycaeus kelantanensis Sykes, 1902  

Sykes (1902) original descriptions on Alycaeus kelantanense – “Shell conic, minutely umbilicate, white in colour, the upper whorls often being yellowish, apparently due to the animal within. Sculpture close well marked rib-striae, with microscopic spiral striation intersecting the ribs. Whorls 5, moderately convex, the last whorl gibbous, and constricted about 2 millim behind the lip, the sculpture being thence much finer and more remote. Aperture subcircular, lip double, the upper outer margin forming a slight wing where it approaches the last whorl.”

Möllendorff (1902) descriptions on Alycaeus (Orthalycaeus) kelantanensis – “T. semiobtecte perforate, turbinate, solidula, subpellucida, subtiliter et confertim costulato-striata, lineis spiralibus tenuissimis decussate, virescenti-albida. Spira fere regulariter conica, apice acutulo. Anfr. 5 perconvexi, sutura profunda disjuncti, ultimus medio inflatus, gibbosus, tum valde constrictus, denuo inflatulus et campanulatus. Tubulus suturalis, circularis; peristoma duplex, internum continuum, leviter expansum, superne appressum, externum valde expansum, superne in alam antrorsum curvatam productum, basi similiter sed minus distincte dilatatum.”
