2008? Bairdoppilata simplex (Brady) .—Brandão, p. 379, figs. 3.20a, b; 4, 5G–H; table 3.

Material Examined: None.

Taxonomic Remarks: The species is firmly identified only from subfossil type specimens at the type locality, and the soft parts are not known. Brandão (2008) demonstrated that, in the Southern Ocean alone, the materials subsequently reported under this name include at least 10 species, and identifications from other regions are even more suspect .

For example, two specimens from the materials identified as B. (B.?) simplex by Maddocks (1969) were re-examined by Brandão (2008, p. 387, figs. 8B, E, H–I, L, P, Q): Female specimen 191F, USNM 121347, was collected at Eltanin station 418, 62 o 39–40’S, 56 o 8–10’W, 311– 426 m. Male specimen 205M, USNM 121348, was collected at Eltanin station 1345, 54 o 50–51’S, 129 o 46–48’W, 915–1153 m. Brandão stated that they represent either one or two different species, which she provisionally identified as? Bairdoppilata sp. 1 aff.? B. labiata (Müller) . The appendages and hemipenis were described, but not the esophageal valve.
