« Protoconch multispiral, dome shaped, of 3-3,5 strongly convex whorls, first 1,5-2 whorls smooth, remainder whorls reticulated with oblique axial costae crossed by spiral ribs of about equal width […]. Teleoconch of 5-6 whorls, weakly angulate near middle of spire, sutural ramp gently concave, whorl sides gently convex; last whorl about 2/3 shell length. Axial sculptutre consisting of 7-8 ptominent, slightly opisthocline, flexuous, and narrowly rounded axial folds; folds regularly spaced, with much broader interspaces, reching from suture to suture on spire but fading out after crossing the shoulder slope and at about the middle of the base. » – P. Mariottini: “Brachycythara beatriceae, a new species from the Alboran Sea and the eastern Atlantic (Gastropoda: Neogastropoda: Conidae)”, The Nautilus vol.121(3), Melbourne (Florida) 2007, p.159-162.

« Spiral sculpture of numerous, very fine threads that densely alternate with bigger interspaces; the subsutural thread shows weel-marked axial denticles. At higher magnification, it can be observed that each interspace consists of several (up to five) rows of rounded tiny granules, each one linked axially to the upper and lower thread by a very fine connection. » – Ibid.
 
The shell differs from that of atlantidea primarily by the darker coloured basal band and by a smaller number of axial folds. Also, in beatriceae, the protoconch has the same colour than the teleoconch, is longer (3-3,5 whorls) than that of atlantidea, and bears this reticulated sculpture made up of sharp axials and spirals. The species is named after the author’s daughter.
