Two damaged specimens, 125 and 135 mm. in total length, from Deception Island, South Shetlands (taken from the stomach of a Blue Whale); and two others, 67 and 69 mm. in total length, from the stomach of a Fin Whale, captured in the Weddell Sea (65° 04' S, 54° 12' W), appear to belong to this species.

As in the young of C. kathleenae, the eye is proportionately smaller in these small examples, the diameter being about 5 in the length of the head in specimens of 67 and 69 mm. The pelvic fin-rays are simple, and the pelvic fins are entirely pale. Genus CHAENODRACO Chaenodraco, Regan, 1914, Ann. Mag. Nat. Hist., (8) xiii, p. 13; 1914, Rep. Brit. Antarct. {'Terra Nova') Exped. 1910, Zool. i (i), p. 12. Type Chaenodraco wilsoni, Regan. Closely related to Chionodraco, but the supraorbital ridges are not crenulated, the gill-rakers are developed as dentigerous prominences, and the pelvic fins are each formed of a spine and only four rays.

Chaenodraco fasciatus, Regan, 1914, , p. 14; 1914, , p. 13, pi. ix, fig. 2. Fig-51- Chaenodraco wilsoni. x \. Depth of body 6 to 7 in the length, length of head z\ to 3. Snout less than \ length of head; diameter of eye 4 (young) to 4, interorbital width 3f to 4I in length of head. Rostral spine antrorse. Jaws equal anteriorly or lower a little projecting; maxillary extending to below anterior J or of eye. Operculum with a group of 4 or 5 spines, the uppermost bi- or tri-fid; 12 to 14 gill-rakers on lower part of anterior arch.
