Type material: none designated, syntypes in ZMB, reference 22577 .

Distribution: Widely distributed in the southern oceans, generally found south of the tropic of Capricorn ( Holmquist 1957), but also occurs throughout Asia ( Liu & Wang, 2000) and northward to Sagami Bay, Japan ( Ii 1964).

Distribution in New Zealand: East of Cook Strait.

Ecology: Pelagic, deep water (300–1300 m) ( Holmquist 1956).

Remarks: Ii (1964) described two subspecies; B. rostrata japonica and B. rostrata orientalis , and Liu & Wang (2000) recognized a third subspecies B. rostrata rostrata . The only material known from New Zealand waters are three immature specimens collected during the “Discovery” expedition and classified by O.S. Tattersall (1955) as B. rostrata . O.S. Tattersall herself cast some doubt on the species identification, but did not give suggestions on potential subspecies.
