Hab. Falkland Islands. 



In addition to the above, Mr Bennett has sent 4 specimens (58-92 mm.) from Stanley, 

 Falklands, and there are 5 others (45-115 mm.) in the British Museum collection, 

 including two of the types of the species and the type of Ly codes flavits. 



Mr Bennett notes that his specimens were secured from among the hollow tangled 

 roots of "kelp" (Macrocystis), and the type of Lycodes flavus was obtained by 

 Mr Vallentin in exactly the same manner. 1 Two of the specimens collected by the 

 'William Scoresby' in February, 1932, are females with ripe ova.
