Snout nearly \ length of head; diameter of eye 5I (young) to nearly 6, interorbital width 31 to 33 in length of head. Lower jaw a little projecting; maxillary not nearly reaching vertical from anterior margin of eye; 14 or 15 gill-rakers on lower part of anterior arch. About no scales in the upper lateral line, which follows the dorsal profile. Dorsal 61-66. Anal 35-38. Pectoral with 22 or 23 rays, length 2 to zl in that of head, not nearly reaching vent; pelvics as long as or longer than pectorals (much longer in young), not reaching vent. Caudal rounded. Yellowish or greyish-brown; traces of a dark line on each side of the snout, a dark spot below the eye, and a dark bar running back- wards from the eye towards the suboperculum; body with about 7 rather indistinct dark cross-bars on the back and upper parts of the sides; dorsal, anal and caudal more or less dusky, at least in adults, the dorsal with two narrow longitudinal dark stripes running for the whole length of the fin; pectorals and pelvics pale. Fig. 38. Cygnodraco mawsoni. x\. Hab. Mac-Robertson Land; Queen Mary Land. The type of the species, 466 mm. in total length, was taken off Drygalski Island (65° 42' S, 92° 10' E), at a depth of 112 metres. The above description is based mainly upon 6 specimens, 125 to 360 mm. in total length, obtained by the Antarctic Research Expedition, at a depth of 219 metres. Genus PARACHAENICHTHYS Parachaenichthys, Boulenger, 1902, Rep. Coll. Nat. Hist. 'Southern Cross', p. 176. Type Chaenichthys georgianus, Fischer. Very closely related to Cygnodraco, but with the head and anterior part of the body more or less depressed and the interorbital region broader. The upper lat
