Represented in deep water about the Galapagos Islands by 



1572a. MYCTEROPERCA OLFAX RUBERRIMA, Jordan & Bollman. 



A large specimen taken by the Albatross at Abingdon Island, in the 

 Galapagos, seems to have been bright red in life. It probably represents 

 a deep-water variety analagous to the red varieties of West Indian 

 species. The anal is a little lower than in an equally large specimen of 

 the typical olfax taken in the same locality. No other difference is 

 apparent. Abingdon Island, Galapagos Group, (rulerrinius, very red.)
