Description

"Shell of ''Conasprella nereis'' is thin delicate smooth and glossy, its outline straight-sided and elongate; the shoulder is smooth, sharp and distinctly carinate with a small groove just anterior to the shoulder carina. The anterior one-third of the shell has six to eight wide and deeply incised spiral sulci. Shell colour is pale blue-white with three light brown bands: one just anterior to the shoulder, one at mid-body and one anterior to the mid-body line. Three to four rows of alternating brown and white dashes between brown bands: dashes are rectangular-shaped, giving the shell a checkerboard effect. Spire colour is white with alternating dark brown, crescent-shaped brown flammules, said flammules extending from the suture across the shoulder, on to the body whorl, producing a pattern of alternating white and dark brown dashes along the shoulder carina. The aperture of the shell is pale lilac, and its periostracum is thin, smooth and translucent yellow-brown." The length of the shell varies between three 19 mm and 27 mm.
