Rather small, slender, with the nucleus of 2 2/3 convex whorls, the first 1 ½ smooth, the next with rather strong spiral cords and slender axial riblets. This sculpture passes by a short transition into that of the first neanic whorl, with coarse protractive ribs arched back in the subsutural region, and spiral cords. Subsequent whorls with less curved ribs passing weakly over the flat anal fasciole. Lip thin, a varix some distance behind it. Anal sinus moderate, extending to suture, but the greatest depth of its rounded end distinctly below the suture. No stromboid notch. No parietal callus at the posterior angle, the inner lip "erased," without definite outer edge. Siphonal canal of moderate length, not contracted. Type C. delgada.

The sculpture of the nucleus, form of the anal sinus, etc., differentiate this group from Daphnella. The nuclear whorls have some resemblance to those of Eucyclotoma and Asperodaphne, genera differing from Cacodaphnella in various other characters.
