Galii. Leucosiidae III. Urnalana gen. nov. Zool. Med. Leiden 79 (2005)

lacking median furrow, lateral margins constricted subdistally; 6^th abdominal segment glabrous, median denticle minutę. Shaft of małe l^st pleopod short, stout, sinuous, dis-tally setose; digitate, cornuted apical process partly concealed by subdistal setae.

Colour.— "the anterior half of the carapax was bluish-white, the posterior half dot-ted with red; a band of crowded red punctae across the middle, interrupted at the median dorsal linę. Below white, with a few scattered red dots" (Stimpson, 1907:152).

Remarks.— Miers (1879: 40) and Stimpson (1907) noted the Japanese specimens they described as Leucosia haematostica differed in their colour pattern from the typical form described by Adams & White (1849), as well as in having "the tubercles on the arms proportionally smaller but similarly disposed, the postabdomen of the małe with the sides nearly straight and the second joint not constricted". Miers ascribed these features to "the difference in age of the specimens, which agree in the form of the carapace, front, thoracic sinus, and legs". However, as comparison with the type materiał of L. haematostica and additional materiał (see above) added to the list of distinguishing characters the form of the małe l^st pleopod, it is described as a new species, U. parahaematostica.

Distribution.— Japan, Korea, Taiwan; 66-101 m depth.
