 appear first, at any rate in Plmragrdnima. 



Of the forms identified the Lirvac of tlie Nototheuiinae differ from the rest in llie 

 small size of the volk-sac. Of those with a large yolk-sac Artedidraco is distinguished 

 from Gi/mnodraco l.y tlic short tail, whilst the ( 'ha«Miiclithyidae differ Innn hmji in ijic 

 wide mouth and the early development of the pelvic fins.* 



Except Pleuragramma cirtarcticum larval and post-larval Nototheuioids have only 

 l)een taken quite near the coast. There is some evidence that the young of Notothenla 

 macrocephala, a widely distributed species, may be pelagic.
