. Bulletin - United States National Museum. Science. FiG. 596.—Argeia pugettensis. a, Dorsal view of immature female, b. Ventral view of SAME. X 14^. (Second post-larval stage.) sal view they appear attached to the lateral margins of the segments. They form a border around the abdomen. The inner branches are rounded, sac-like bodies, usually decreasing in size f I'om the iirst to the last. There are five pairs of incubatory lamelLT? which do not completely inclose the marsupial pouch. The distal part of the first pair has the posterior margin not produced in a lobe. The legs are all prehensile. The basis of all seven pairs is provided with a high rounded carina. The male is narrow, elongate, symmetrical in outline, 5i mm. long and li mm. wide. Eyes are present. The anterior margin of the head is widely rounded. The first pair of an- tennae are composed of three articles. The second pair are composed of four articles. All the thoracic segments are distinct. The lateral margins are straight, but not contiguous. All seven pairs of legs are prehensile. The seg- ments of the abdomen are coalesced in a single segment, narrower than the thorax, which tapers to a point. It is 1 mm. wide and 1^ mm. long. There are no uropoda and no pleopoda. The individual described was found in the branchial cavity of JVec- tocrangon Pig. 697.—Argeia pugetten- sis. (Cryptoniscan stage.).
