Plates 110, 111
Shell reaching 103 mm. (about 4 inches) in length, imperforate and finely sculptured. Color a uniform dull, grayish tan with a faint indication of spiral bands of brown. The fasciole is brown; interior of aperture salmon. Whorls 5 and strongly convex. Spire moderately extended and produced at an angle of about 50°. Aperture subovate. Outer lip thin and simple. Parietal wall with a broad glazed area which is sharply margined. Columella nearly straight and with 3 strong plicae. Suture deeply impressed. Spiral sculpture consisting of numerous, fine, incised, spiral threads which are strongest on the early whorls. Axial sculpture consisting of fine growth lines. Protoconch small and poorly defined. Periostracum probably thin and deciduous. Operculum lacking.
Radula uniserial, consisting of rachidian teeth, each tooth with three fang-like denticles.
Upper surface of the foot a mottled salmon pink, edged with ivory; the under surface a uniform ivory. Head with a central and two large lateral lobes; the tentacles located at the junction of the lobes. Eyes minute, black and located on the lateral lobes at the base of the tentacles on their outer side. Head a mottled salmon, edged with ivory; the tentacles and mantle ivory. Siphon ivory, with two large equal lobes at the base. Osphradium and gill set well back from the base of the siphon. Anatomy similar to that of Odontocymbiola magellanica and americana.

Types. The holotype is in the Museum of Comparative Zoology, no. 233795, from about 160 miles ENE of Mar del Plata, Argentina, on a mud bottom. Collected by the fishing vessel Pescal II and received from E. de Carvalho Rios of the Museu Oceanográfico de Rio Grande, Brasil.
Remarks. This species differs from O. magellanica Gmelin in having more convex whorls, having a fine spiral sculpture and a much more highly developed fasciole which extends beyond the base of the columella. In addition, the spire is more attenuated in O. pescalia, being seven-tenths the length of the aperture, while in O. magellanica the spire is one-half the aperture length.
O. pescalia resembles superficially Adelomelon riosi, but differs in being much smaller and in having a very different radula.”
