Marine isopods collected in the Philippines by the fisheries steamer Albatross in 1907-08 . le. Eyes ab-sent. Terminal segment of body with posteriormedian lobe, on either side of which is asmall triangular process; uropoda small,consisting of a single article. The legs are all ambulatory, similar,with dactylus uni-unguiculate. They arealike in both sexes. This genus differs from NannoniscusSars, its closest ally, in lacking the largemedian lobe of the head, in not having anolfactory papilla to the first antenna, inthe differently shaped abdomen, and inhaving the uropoda composed of a singlearticle and not double-branched as in thatgenus. The type of the genus is Nannoniscus fig. 4.—haploniscus ex-bicuspis In 1899, Sars admitted CISDS-that this species was not congeneric with the type species of the genusNannoniscus, but allowed it to remain there. The following species also belongs to this genus and is very similarto Sarss species. HAPLONISCUS EXCISUS, new species. Body oblong-ovate, a little less than twice as long as wide. Colorin alcohol whitish. Surface a Norwegian North-Atlantic Expedition, XIV, Zoology, Crustacea, I, 1885, 76 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. XXXV.
