Wilson, loc. cit., p. 444, pis. 70, 71. 1948. Barnard, Ann. Mag. Nat. Hist, (xii), 1, p. 247. $—Carapace subcircular, about as wide as long, considerably more than half total length. Eyes minute. 4th segment rather prominent laterally, not as wide as genital segment, which is ovoid, longer than broad in adult. Abdomen of one segment, oblong, shorter than genital segment in adult. Furca with simple rather widely diverging Fig. 11. Lepeophtheirus insignis Wilson, a, immature ?, 6th leg further enlarged; b, <$; c. furca. o*—Similar to $, but carapace relatively slightly larger. Genital segment ovoid, with rudiments of 5th and 6th legs. Abdomen 2-segmented. 9 11*75 mm., carapace 6-5 mm., £ 6-6 mm., carapace 4 mm. (Wilson). Yellowish, chitinous ribs and thickenings on carapace purple, internal oviducts orange, ovisacs yellow (Wilson). White marbled with reddish-grey (). Locality. Table Bay, on Sunfish {Mola mold). 1 immature $, i(J (). Distribution. Coast of Southern California, on Mola mola. Remarks. The £ (carapace 4x4 mm.) corresponds closely with Wilson's description. The $ (carapace 5X5 mm.) clearly belongs to Wilson's species but is in a stage intermediate between the young $ figured on pi. 71, fig. 51, and the adult figured on pi. 70, fig. 37; the genital segment is more ovoid than in fig. 51 but has not reached its full length as shown in fig. 37. The 6th leg is narrower than in fig. 51; there is no trace of a rudimentary 5th leg. (Comparison of pi. xxii, fig. 273, and pi. xxv, fig. 311, in Wilson's 1905 paper.
