DISCOVERY REPORTS 



doubt as to the identity of TV. macrocephala with species from Kerguelen and New 

 Zealand, particularly on account of the wide range of variation in the number of spines 

 in the dorsal fin (III-VI). Comparison of Magellan and New Zealand material leaves 

 no doubt that the same species is found in both regions, and two young individuals 

 collected by the ' Challenger' at Kerguelen agree closely with young from the Falklands. 

 It seems probable that this and the following species are not so demersal or littoral in 

 their habits as most of the other species, and that the silvery young are mainly pelagic.

Fig. 43. Notothenia macrocephala. 



x*. 



In life this fish is blue-grey or golden-brown above, shading away to golden-yellow 

 or cream on the belly; the branchiostegal membranes are bright orange-yellow; the 

 dorsal fins are blue-grey, the other fins grey. It grows to a length of considerably more 

 than a foot, and is known locally in the Falklands as "Yellow-belly". Mr Bennett 

 notes that it is a good fish for the table, although seldom used for food. It stays later 

 in the Falklands than the other species of Notothenia, and has been found to be abundant 

 as late as 25 April.
