Material. 1 A F, Bairdoppilata (Bairdoppilata?) simplex (Brady, 1880), RV Eltanin station 418, 62°39–40’S, 56°8–10’W, 311 to 426m, Ref. 58, USNM 121347. This living female was illustrated by Maddocks (1969, p. 77, fig. 42B); this is Maddocks’ specimen no. 191. 1 A M, Bairdoppilata (Bairdoppilata?) simplex (Brady, 1880), RV Eltanin station 1345, 54°50–51’S, 129°46–48’W, 915 to 1153m, USNM 121348. This living male was identified and illustrated by Maddocks (1969, p. 77, Fig. 42 A, C–H); this is Maddocks’ specimen no. 205.

Measurements (Fig. 4) . USNM 121347: RV, A F L 1.97mm, H 0.97mm. USNM 121348: LV, A M L 1.70mm, H 0.96mm; RV L 1.68mm, H 0.90mm. ZMH K­41363: LV, L 1.00mm, H 0.56mm. Remarks . Specimens from the Pacific Sector of the Southern Ocean – one male, USNM 121348, and off Northern Antarctic Peninsula – one female, USNM 121347 – identified by Maddocks (1969) as B. simplex are included herein. They differ from B. simplex in the same features as B. simplex differs from ? B. labiata (see Remarks from ? B. labiata ). These two specimens are similar to ? B. labiata, but their LV present a more rectilinear outline, with slightly concave anterodorsal margin (instead of slightly convex); dorsal margin of RV presents relatively shorter medial segment (Figs. 5.A–F, I–K, N). Additionally, the adult female (USNM 121347) is considerably larger than the lectotype of B. simplex . Moreover, the three males of ? B. labiata from the Gausstation (ZMB 13069) present different hemipenis morphology than the male from the Pacific sector of the Southern Ocean ...
