Marine isopods collected in the Philippines by the fisheries steamer Albatross in 1907-08 . ed with hairs. Theouter branch of the uropoda is narrow and produced to a blunt extremity. The innerbranch is twice as wide as the outer branch, has the posterior margin straight in themiddle, with the inner postlateral angle rounded and the outer postlateral angleproduced to a blunt extremity. The last three segments of the thorax, the abdomen,and the uropoda are thickly covered with stiff setae, or spines, those on the abdomenbecoming denser and longer. The first three pairs of legs are prehensile, the last fourpairs ambulatory. The prehensile legs have the merus armed with four spines. Only one specimen, a female, was collected at station 5254, Linao Point, N. 44° E.,1 mi. (7° 02 00 N., 125° 37 45 E.), at a depth of 21 fathoms, in sand and specimen, catalogue number 40911, United States National Museum. I have placed this species in Stebbings genus Argathona a notwithstanding the slightdifference in the form of the second maxilla, which, instead of ending in a curved,. a bee Fig. 8.—Argathona setosa. a, Abdomen, X 9§; b, maxilliped, X 271; c, first leg, X 20£; d, first maxilla, X 38$; e, second maxilla, X 51f. sharp unguis, seems to end bluntly. There is also an additional article to the maxil-lipeds, btit this may have been overlooked in Stebbings specimen. This species is very similar to Stebbings species, Argathona normani, but differs inlacking tubercles on the last two thoracic segments and on the fourth, fifth, and sixthsegments of the abdomen. The shape of the inner branch of the uropods is also differ-ent. Stebbings specimens were from the Gulf of Manaar and south of Galle. Argathona sulcata, sp. nov. Body oblong-ovate, times longer than wide, 8 mm.: 20 mm. Surface light yellow. Head wider than long, 2 mm.: mm. Anterior margin rounded and produced inthe middle in a very small, median point. Eyes twice as long as wide,
