They are small tubular nostrils, and take the form of a pair of flattened, somewhat elongate sacs, each opening by a small pore, and appearing as a tag of black skin, 0-9 cm. long, a little above the level of the eye and just behind the distal end of the maxillary (Fig. 1 A).

. Discovery reports. Discovery (Ship); Scientific expeditions; Ocean; Antarctica; Falkland Islands. 6 DISCOVERY REPORTS in both the new specimen and that of Regan, and they have a very similar appearance in both. They are small tubular nostrils, and take the form of a pair of flattened, somewhat elongate sacs, each opening by a small pore, and appearing as a tag of black skin, 0-9 cm. long, a little above the level of the eye and just behind the distal end of the maxillary (Fig. 1 A). The lateral line system of the new specimen has been followed only in the head region, where it forms a curving line of small black papillae arranged in a single, regularly spaced row. It begins at the tip of the lower jaw and runs downwards and backwards to curve up again and extend half-way across the smooth region of the gill covering. A little distance from its beginning on the lower jaw, the lateral line sends a short branch, with relatively few papillae, as far as the articulation of the jaw (PI. I). The older authors (Lutken, 1878; Gill, 1878) have denied the existence of a lateral line among the Ceratioidea. Gunther (1887) mentions pores, scattered over the skin of' C. uranoscopus' and ' C. caruncidatus\ which secrete luminous mucus; these may be referred to the lateral line. Later, Regan & Trewavas (1932) described the various modifications of the lateral line organs of Ceratioids, and classified the Ceratndae.
