A coloured drawing,' of a fish from the Bransheld Straits reproduced by Lonnberg 

 (Swedish S. Polar Exped. Fish. pi. n, fig. 7) as Artedidraco skottsbergii seems rather 

 to represent a Pogonophryne, perhaps even the species here described. 



This species is named in memory of Captain R. F. Scott, R.N., c.v.o.
