Planche 1 issued from : T. Park in Bull. Scripps Inst. Oceanogr. Univ. California, San Diego, 1995, 29. [p.186, Fig.76].
Female: a, forehead (left side); b, urosome (left); c, d, genital somite (left, right, respectively); e, A2; f, Mx1 (first inner lobe omitted), posterior; g, exopod of P1 (anterior); exopod of P2 (anterior).
Nota: Cephalosomal appendages similar to those of P. norvegica except that seta on 2nd exopodal segment of A2 much developed. Outermost seta on basis of Mx1 also well developed. In P1 exopod, outer spine of 1st segment very small; that of 2nd segment short of reaching base of following outer spine. In P2 exopod, outer spine of 2nd segment extending beyond distal end of following outer spine and about as long as 2nd outer spine of 3rd segment; incision separating 2nd marginal lobe of 3rd segment relatively deep.

Male: i, forehead (left); j, last pedigerous and genital somites (left); k, exopod of P1 (anterior); l, exopod of P2 (anterior); m, exopod of left 5th leg (medial); n, distal exopodal segments of left 5th leg (medial, tilted counterclockwise); o, idem (lateral, tilted clockwise); p, idem (anterior, tilted counterclockwise).
