Ocular tubercle rather tall, conical; proboscis long, swollen medially, taperingnoticeably in distal third; segment 4 of palp almost twice shorter than segment2; tarsus and propodus subequal ............................................ *C. nasuta (p. 128)*Colossendeis macerrima Wilson, 1881(Pl.

The distribution range is wide: C. macerrima occurs in the bathyal zones of thePacific, Atlantic and Indian Oceans.*Colossendeis nasuta Hedgpeth, 1949(Pl. XXIII, figs. 4–6)Hedgpeth, 1949: 302–303, fig. 46e–h.Only one find has been recorded up to now, south-west of Kyushu Island at adepth of 710 m.*Genus Hedgpethia Turpaeva, 1973 2Type species: Colossendeis articulata Loman, 1908.Trunk elongated, segmented; segment 1 longest. Lateral processes separated bynot more than their diameters. Proboscis robust, much longer than trunk, greatlyexpanded medially, in some species with short “neck”. Abdomen very small, situatedalmost ventrally and pointed vertically downward. Chelifores absent; palps andovigers 10-segmented.One species is found in the Sea of Japan.*Hedgpethia californica chitinosa (Hilton, 1943)(Pl.
