Original description of Pelicaria marwicki by Finlay, 1931:
- "Shell closer to coronata Tate than to clathrata Tate, but, like these two, much shorter in the spire and with a more thickened aperture than the Recent scutulata Mart. It has the short spire of clathrata, but no lamelliform axials; whorls angled, and growth lines and outer lip far more sigmoid. Related to coronata in general habit of shell and callus deposit (which extends over whole of body whorl, and sometimes ¼ of next whorl; clathrata has only two-thirds of a whorl callused over) and the tendency to sulcation of the suture anteriorly, but this never goes to the same depth and extent, the callus shoulder remaining mostly as a flat or lightly concave platform. Shell more squat than coronata, spire being lower than aperture; angle of whorls much less developed and lower down, almost entirely hidden by callus on penultimate whorl. Peripheral knobs about the same in number, but very much weaker; small sharp tubercles instead of projecting nodules. Apertural callus very heavy, forming three marked “lips,” one projecting upwards and outwards at suture, another forming a pad on base, a third at end of the strongly marked fasciole. Columella very much bent (almost a semicircle) to the right."
