P3 is 2 mm. long, with 7 segments. The disk is mm. in diameter. No. 4 (station 45): The centrodorsal is hemispherical. The cirri are about XXV, in two rows, 9-11, from to mm. long. The segments are very markedly constricted centrally, those before the antepenultimate being twice as long as broad and the antepenultimate half again as long as broad. The cirri in the distal row have very much longer segments than the others, with relatively large opposing spines a. d dTZ mm Figure 9.—a, Anledon longicirra (A. H. Clark), longest cirrus segment, b, A. farviflora (A. H. Clark), longest and c, distal- most cirrus segments, d, A. iris (A. H. Clark), P,. and terminal claws. The IBri are six times as broad as long. The IBr2 are rhombic, twice as broad as long, shorter and with sharper lateral angles than in the preceding specimens. The arms are 15+ mm. long, rather smooth; the first brachials are basally in contact interiorly. The distal intersyzygial interval is 3 muscular articulations. Pi is mm. long, with 8 segments. P2 is mm. long, with 6 segments. P3 is mm. long, with 7 or 8 segments and bearing a genital gland. The disk is mm. in diameter and the anal tube is mm. in height. No. 5 (station 45): The cirri are about XXV, 10-11, from 2 to 3 mm. in length; the fourth segment is about four times as long as broad. The arms are about 15 mm. long. Pi is mm. long, with 6 segments. P2 is mm. long, with 4 segments, or lacking. The disk is 1 mm. in diameter. No. 6 (station 44): The cen
