Cnemidocarpa platybranchi a Millar, 1955

Cnemidocarpa platybranchia Millar, 1955: 226 ; Monniot et al., 1976: 1192; Monniot and

Monniot, 1984: 141; 1985a: 294; 1985b: 28; Sanamyan and Sanamyan, 1999: 1850. Bathystyeloides enderbyanus: Monniot and Monniot, 1970: 323 (part).

Material examined. St. 4104, 5110±5120 m, one specimen.

Remarks. According to Monniot et al. (1976: 1192) the ®rst (most dorsal) longitudinal vessel on the right side of the branchial sac is notably larger than the remainder and`the transverse bars in this region are raised into laminar expansions’. Actually, there is an inverted fold, like those described by Sanamyan and Sanamyan (1999) for Styela tenuibranchia Monniot, Monniot and Millar, 1976 .

This is the ®rst record of the species below the Antarctic Convergence. The species was previously recorded from the north and central Atlantic, the central Indian Ocean and from the Tasman Sea .
