Berry 1909, p. 418 (locality record only). Scaeurgus patagiatus Berry 1913, p. 564. Body short, rounded, firm, compact, nearly or quite as broad as long; widest anteriorly or near the middle, evenly rounded behind; much flattened ventrally, with a conspicuous median longitudi- nal groove; dorsum arched; sides rounded, often flattened or sunken above the periphery in preserved material giving an angular appearance. Mantle opening wide, reaching a little more than halfway between the funnel and eye. Surface (except on the funnel and ventral aspect of the head and arms) everywhere thickly covered with small distinct rounded papilla or tubercles; on the ventral surface of the mantle they are in the main separate and irregularly but evenly distributed; on the dorsal surface they have a tendency to run together and arrange themselves in more or less irregular longitudinal series, occasionally forming short low ridges similar to those which have been remarked in Polypus marmoraius. These ridges also recall those of P. marmoraius in their position and frequent bilateral symmetry; four of them form the usual quadrilateral on the dorsum, besides various others more laterally situated. A conspicuous series of similar but less obscure ridges begins a short distance from the base of the arms (affecting all of them except the ventral pair), and extends along their outer surfaces, reaching its maximum on the third pair, where it results in a nearly continuous fold. A narrow keel-like ridgeor fold bounds the periphery of the body from a point on either side opposite the base of the funnel nearly to the posterior; in the gap where the resulting lateral folds are discontinuous on the extreme posterior point of the body is a large soft vertical papilla of elongate- conical shape.
