Asperdaphne capricornea: Shell small, lanceolate, contracted at the sutures; substance rather thin and translucent. Colour either white, buff, or pale pink above, afterwards turning to buff or white; three apical whorls always darker, usually brown buff. Whorls seven and a half, including a protoconch of two whorls. Sculpture : Fine spiral grooves, crossed by still finer radials, ornament the protoconch ; the third whorl has a prominent keel on the shoulder, beneath which is a fainter spiral; on the fourth whorl the radials first appear as eight prominent round-backed ribs, crossed by two, after¬wards three, spiral cords, forming deep meshes by their intersection ; the ribs descend continuously and obliquely from whorl to whorl, but decrease in relative importance; the spirals multiply by intercalation till on the last whorl they amount to twenty-five, but there also they are insignificant compared to their initial stage; two or three of the peripheral spirals project beyond the succeeding fasciole; fasciole distinct, crossed by sharp thread-like radials. Aperture: Sinus simple, rather shallow ; inner lip with a slight callus; canal short and recurved.
Length 4,5 mm., breadth 2 mm.
