Daphnella is a genus of conoid gastropods bearing finely sculpted shells with a short anterior canal (Powell 1966).
Characters (Powell 1966): Shell of moderate size, 10–30 mm, elongate-ovate, with long body-whorl, slowly contracted to short unnotched spout-like anterior canal. Body-whorl usually more than half shell height. Protoconch polygyrate, diagonally cancellated. Sinus moderate, sutural, reversed L-shaped. Adult sculpture delicately and densely spirally lirate, usually reticulated by equally fine and dense axial lirae. Frequently irregularly maculated with reddish-brown. Radula a pair of slender awl-shaped marginals, constricted near end, so that point resembles a candle flame.
