Material Examined: None.

Taxonomic Remarks: The species is firmly identified only from the type locality. The lectotype selected by Puri & Hulings (1976) is a somewhat nondescript RV from Challenger Station 300, near Juan Fernandez Island in the Southeast Pacific (33 o 44’0”S, 78 o 10’0” W, depth 1375 fathoms). They reported the dimensions as: RVL 1.46 mm, RVH 0.90 mm (see Fig. 11 View FIGURE 11 ). Supplemental bairdoppilatan dentition was not mentioned and is not visible in their illustration. The calcified inner lamella (infold) of the lectotype is somewhat narrow, and it may be an instar. The soft parts are unknown. Redescription of a larger, preferably living population from this locality will be needed to recognize this species, and all records of B. hirsuta at other localities require re-examination GoogleMaps .

Specimens from Eltanin station 25, in the East Pacific were identified as B. hirsuta by Maddocks (1973), but that identification is dubious. For clarity of communication, a new name, B. hirsutella Maddocks , n. sp., is proposed below for that Eltanin population.

Maddocks (1969) described and illustrated two adult females as B. (B.?) hirsuta (specimen 468F, USNM 121353 About USNM ; specimen 469F, USNM 121355 About USNM ; both from the Gulf of Mexico, 28 o 15’N, 87 o 02’W, depth 1000 m). Their dimensions agree well with the population described from Eltanin station 25 ( Fig. 12 View FIGURE 12 ), but without males a firm identification is difficult GoogleMaps .

Maddocks (1969) also reported subfossil valves from numerous Albatross and Anton Bruun stations, but those identifications are even less plausible. Brandão (2008) demonstrated that the diversity of bairdioids has been severely underestimated in the Southern Ocean and in deeper water.
