A long-, conspicuous s])inc j)r()jocts forward on cither side of the first thoracic segment at tlie place of union of th(> lateral part of the segnientwith the dorsal portion. The same occui's on th(> tliii-d segment. The ahdomen tapers to a bluntly pointed extrem- ity. About two-thirds the distance between the base and the extremity are two strong tubercles, one on either side of the median line. On either side of the median line, where there is a comparatively smooth area, the surface of the a})domen is covered with long and short spines. There are also two long spines on either side of the lateral mar- gin near the middle of the segment, and numerous ones near the base. The first pair of legs are pre- hensile. All the others are ambu- latory, and ver}" much elongated. The uropoda are small, almost inconspicuous, single-branclied, and composed of only one tiny article. A single specimen of this species w^as collected by the U. S. Bureau of Fisheries steamer Alhatross at Station 4390, oti' Santa Catalina Islands, coast of southern California, latitude 33^ 2' 15" north, longi- tude 120° 42' west. Depth, 2,182 fathoms. The type is in the U. S. National Museum, Cat. No. 32072. Family XIX. MUNNOPSID.^.« P^yes wanting. Two divisions of thorax sharply defined. First pair of antenna? with tiagellum well developed. Second pair of antenna^ very nmcli elongated. First pair of legs generally smallcM" than the others, never sulx-hi^li- forni; three following pairs very much elongated and ambulatory in character; last three pairs of legs natatory in character, with some of the joints flattened tind expanded, and fringed with plumose hairs. I'ropoda small. Fleopoda as in the Janiridm. 543.—MuxNA Second leg. x 15^. «See Sars for characters of family, Crust, of Norway, II, 1899, p. Please note that these images are extracted from scanned
