Side-plate i widened below, feebly serrulate; side-plates 5 and 6 more evenly bilobed than in cuspidatus or Stenopleustes nodifer. Postero-inferior angle of pleon segment 3 quadrate, the hind margin nearly straight, and obscurely crenulate. Telson not so strongly boat-shaped as in cuspidatus, apex more deeply incised, each lobe with 3-4 denticles, with fine setules in the notches. Mouth-parts as in S. malmgreni (Sars, pi.

Postero-inferior angle of pleon segment 3 quadrate, the hind margin nearly straight, and obscurely crenulate. Telson not so strongly boat-shaped as in cuspidatus, apex more deeply incised, each lobe with 3-4 denticles, with fine setules in the notches. Mouth-parts as in S. malmgreni (Sars, pi. cxxv, fig. 1) except that the molar agrees with that of cuspidatus (supra) in being rather feeble and conical. Gnathopods 1 and 2 in general like those of cuspidatus, but 5th and 6th joints not so elongate. Peraeopods 1-5 all have the denticle on the dactyl.

Maxilliped, with 3rd and 4th palpal joints further enlarged. Uropod 3, peduncle apically produced as in cuspidatus, inner ramus twice as long as outer, triquetral in cross-section, margins spinulose. Remarks. Although so unlike the preceding species in having no dorsal armature, this species agrees with the former in the mouth-parts, uropod 3, and the dactyls of peraeopods 3-5.
