dispar is a male at 1½ yrs, attaining a total length of 136 mm and body weight of 6.5 g; at 30 months, in the female phase, the length is 169mm and weight 16-3 g. Pandalusjordani matures as a male, and to a lesser extent a female, at about 18 months, reaching a length of 105 m m and weight of 3"8 g; at 2½ yrs all are in the female phase, averaging 118 m m in total length and 5"8 g in body weight. P. platyceros is fast a male at 1½ yrs, attaining a length o f 140 m m and weight of 14.2 g; most remain as males for another year, and at 3½ yrs the total length of 180 n u n and weight 35.5 g. Panda/us hypsinotus matures as a male, and to some extent as a female, at about 1½ yrs, at a total length of 124 m m and weight of 10.3 g; at 30 months the length is 130 turn and weight 12"7 g. Almost as many females as males of P. borea/is mature at l½ yrs attaining a length of 95 m m and weight of 3.2 g; at 30 months, in the female phase, the length is 119 m m and weight 6.1 g. Panda~us danae matures fast as a male, and to some extent as a female, at 1½ yrs, reaching 88 m m in length and 4-4 g; in the female phase, at 2½ yrs the length is 105 m m and weight 8.5 g.
