SYSTEMATIC PART 



MYXINIDAE 



Myxine australis, Jenyns. 



1842, Zool. 'Beagle', Fish., p. 159; Norman, 1937, Discovery Rep., xvi, p. 6. 

 Hab. Coasts of Patagonia and southern Chile; Falkland Islands; South Shetland 



Islands. 



No specimens of this species were obtained by the expedition, but there is one from 

 the South Shetlands in the British Museum collection. This is 230 mm. in total 

 length, and was collected by Mr J. E. Hamilton in 1924. 



RAJIDAE 



Raja georgiana, sp.n. 



St. 39. 25. iii. 26. East Cumberland Bay, South Georgia. From 8 cables S 81° W of Merton 

 Rock to 1-3 miles N 7° E of Macmahon Rock. Large otter trawl, 179-235 m.: i female specimen, 

 185 mm. (width of disc 140 mm.). 



Disc much broader than long, its width about | of the total length ; anterior margins 

 a little undulated but not emarginate ; outer angles rounded. Vent a little nearer to tip 

 of snout than to end of tail. Snout scarcely projecting, its length rather more than 

 1 width of disc ; interorbital width greater than longitudinal diameter of eye and about 

 equal to length of eye + spiracle, which is about 2 in that of snout. Internasal width 

 about I praeoral length of snout. Mouth nearly straight; about 24 rows of teeth in 

 upper jaw. Upper surface of disc more or less evenly covered with small spinules; a 

 single praeocular spine and two postocular spines, of which the hinder is the larger; 

 a pair of strong curved scapular spines set one behind the other ; a single spine on the 

 median line of the back midway between the second postocular and the first scapular 

 spine, and another level with the posterior scapular spines ; a series of similar spines 

 extending in a median line from just behind the suprascapulary region to the first 

 dorsal fin. Lower surface quite smooth. Dorsal fins close to end of tail, their bases 

 contiguous. Pale greyish-brown, mottled and spotted with yellowish-white; hinder 

 margins of pectorals and edges of pelvics with a narrow pale border; lower surface 

 yellowish-white, with a dusky tinge towards the hinder parts of the pectorals and pelvics. 



Hab. South Georgia. 



This species appears to be most nearly related to R. macloviana, Norman, from the 

 Patagonian region, and R. miirrayi, Giinther, from Kerguelen, but differs from both 

 in the shape of the disc, in the smaller eyes, in the greater internasal width, and in the
