Deevey, 1968
Diagnosis
Only the male has been fully described previously. The carapace tapers posteriorly (B. kornickeri Habitus 1, B. kornickeri Habitus 3). Dorsal surface with central hollow at about midlength. Carapace glands situated symmetrically in slots on either side of postero-dorsal corner. The ventral margin curves smoothly from beneath the incisure through to postero-dorsal corner. Sculpture strikingly punctate over entire surface especially on and beneath the rostrum: along the anterior margin striae merge to form irregular polygonal cells (B. kornickeri 3). A flange of sculpture fringes the posterior margin. In ventral view, flanks curve smoothly from tips of rostra to posterior margin; maximum width anterior to midpoint. Frontal organ absent. The first antenna with about five segments and a hirsute dorsal seta, one long and three medium length thick-walled setae in addition to ca. 250 thin-walled setae on ventral pad (B. kornickeri 1, B. kornickeri 4). Second antenna endopodite with unequally long "a" and "b" seta on elongate first podomere. The righthand hook appendage powerfully developed with three setae inserted at the end of its shank (B. kornickeri 5). The lefthand hook appendage is reduced to just a shank. The sixth limb with three terminal setae longer than the limb itself. The type specimen had lost its caudal furca.
Remarks
Original material is in a poor state.
Distribution
Apart from the type locality, this species has only been taken in the N. E. Atlantic, always in nets fished very close to the sea-bed at abyssal depths. 1 (R.R.S. Discovery Map).
Type specimens
Holotype male dissected on slide deposited in the Smithsonian Institution (USNM 123214).
Type locality
28°15'N 87°02'W from the intestine of a bottom fish, Dicromita agassizii, taken in a midwater trawl which hit the sea-bed at a depth of 1000m, 11 July 1966.
