Janiropsis californica Richardson, Harriman Alaska Exp., Crust., X, 1904, pp. 223-224; Proc. U. S. Nat. Mus., XXVII, 1904, i)p. ()()()-0fi7. Locality.âSausalito, California. Body narrow, elongate; .surface smooth; coloi- uniformly whitish. Head with a prominent rounded median lobe on tlu? anterior mar«-in: lateral angulations rounded; lateral margins straight and converging toward the base. Eyes black, distinct, but small, and simple in structure. First pair of antenme are composed of six joints and extend nearly to the middle of the fifth joint of the peduncle of the second pair of antetuuv. Second pair of antenna? are about equal to one-thii'd the length of the body; the flagellum is composed of nineteen or twenty joints. The first thoracic segment is but little wider than the head; the margins are entire, lateral lobes rounded. The second segment has the lateral margin straight, with the epimeron showing slightly along the edge. The third and fourth segments have the antero-lateral lobe rounded, the posterior margin straight, with the epimeron showing as a rounded lobe. The fifth, sixth, and seventh segments have rounded lateral margins, with epimera showing on the posterior part of the segments. Terminal segment rounded posteriorly with smooth margins, and a median lol)e between the uropoda. Uropoda very short, about half as long as the ter- minal segment. Branches about ecpial in length and twice as long as the peduncle. Legs simple, ambulatory, similar in shape and size, and bi-unguiculate. Only two good specimens, both females, were taken at Sausalito, California, by Doctor Ritter and part3\ Two imperfect specimens also are from the same locality.
