? Bairdoppilata sp. 1 aff. ? B. labiata (Müller, 1908) (Figs. 3.15, 3.17, 4, 5.E, F, N, 8.B, E, H, I, L, P, Q, 9.G–L, 12.O–Q) 1969 in part Bairdoppilata (Bairdoppilata?) simplex, Maddocks: 77–78, Fig. 42. 2000? Bairdoppilata cf. B. simplex, Dingle: 486, 488, Figs. 2, 3, 5.C, table. 2. 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. 42 B); 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. (Herein Figs. 3.17, 4, 5.E, F, 8.E, H, L, P, Q, 9.G–L). 1 RV, ROSSMIZE, # H in 4, ZMH K­ 41363 (Herein Fig. 12.P–Q). Distribution. Southern Ocean (Atlantic and Pacific Sectors), 196 to 426m. 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 K­ 41363: 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 ...
