Two larvae from tlic'" Terra Nova'' collection, taken at Cape Evans, ^Ic.Murdo 

 Sound, mav lie refeiT<'d to this species. The smaller. 11 lum. long, was captured on 

 ^lav l:lth: the laigcr, I.") nnn. loug. ou .hiue L'stli. 191 I. at a depth of 20 metres. 

 Two somewhat larger specimens, 19 and 20 mm. long, wt'i-e olitaiiie(l |i\ the 

 "Discovery" at lioss Island. 



The wide mouth, cleil lo helow o|- lieyond the ])osterior edge of the e\'e. at once 

 distinguishes these larvae from those of the Nolotheniid.ie .and ISathydraconidae ; 

 another distinctive feature is the precocious dcvclopmeut of the pelvic tins. The 

 i-elativelv short tail, the small ntnnlier of myotomes, and the Mack colour of the peKic 

 lin memlirane are characteristic of this s])ecies. 



The series illustrates well the growth of the |Moduced snout of tlu' ailult tish fi'om 

 the snul)-nose(l I'orni of the larva.
