Described from a single specimen. The mantle is grey and smooth, with black and opaque white spots scattered over the dorsal surface. The black spots are more numerous than the white. Berthella canariensis and B. californica differ from most species of Berthella in having a tuberculate gill rachis. In most species of Berthella the rachis is smooth.
