Hawk," at 155 fathoms. The observation which I have made on previous occasions, viz., 

 that the young of many deep-sea fishes live on the surface, or much nearer to it than 

 the adult, seems to be fully borne out by this species. Collett remarks that during the 

 breeding season individuals are seldom taken at a depth less than 100 fathoms ; the 

 majority probably producing their young ^ in far greater depths. The fry rise towards 

 the surface shortly or perhaps immediately after birth, choosing for their haunts the 

 upper strata of the sea, and do not descend to any considerable depth till they have 

 attained a length of about 50 or 60 mm.

This fish was discovered oif Inosima in 365 fathoms, and therefore is to be included 

 among the deep-sea group. For the sake of comparison it was described in the Report 

 on the Shore Fishes. /

 Vert, \^, Several specimens were obtained at Stations 306 and 307, near Magellan 



Strait, in 147 and 345 fathoms. This species, however, lives at certain times or localities 



much nearer to the surface, and is not uncommon along the Antarctic coasts of South 



America. 



1 This species is viviparous.
