Description

Body rounded-ovate to ovate. Head of moderate size, poorly delimited. Eyes little swollen. Funnel organ composed of two narrowly connected dorsal segments and two elongate-oval discrete ventral segments. Arms stout, much coiled, rather short, the longest less than three times the length of the body, with the formula usually 4, 3, 2, 1; dorsal arms weakest as well as shortest. Suckers large near umbrella mar' gin in both sexes, but not abruptly so. Third right arm of male short, about 76 per cent, of its mate, its copulatory fold wide and open with a very narrow marginal groove which terminates in a fleshy calamus; ligula also fleshy, minute, about 4.6 per cent, as long as the arm, its concavity shallow and crossed by nine or ten weak transverse ridges and grooves. Umbrella delicate, webbing the arms for 22 to 31 per cent, of the length of the longest, thence continuing a little way out the dorsal angle of each arm as a soon obsolescent carina, but on the ventral angle as a wide velumlike membrane to the tips of the arms; web formula inconstant except that sector A is a little the shortest. Integument closely papillose, more regularly so below than above, the oral surface of the umbrella also papillose; a distinct supraocular cirrus present, with one or two slightly enlarged papillae in front of it. Color in preservation near Wood Brown, consistently clouded dorsally with Fuscous; oral surfaces paler. Ctenidium very large and plumelike, with 15 to 17 lamellae to a side. Measurements of holotype: Total length 135, length of body 3 7, of longest arm 90, of R. 3rd arm 65, of ligula 3, of sector D of web 28 mm. Type-Locality: 50 fathoms, off San Juanico, Baja California; Ben Fukuzaki, in -net, Aug. 1952. This very distinctive species is characterized by the short arms, webbed to the tips ventrally by the velum-like prolongations of the umbrella margin, the peculiar fleshy hectocotylus, tripartite funnel organ, and large plumelike ctenidia. The specific name is derived from the L. velum, veil, + gero, a bearer.
