70. MYCTEROPERCA RUBERRIMA (Jordan & Bollman). 



Mycteroperca olfax ruberrima JORDAN & BOLLMAN in Jordan & Eigenmann, 

 Review Serranidce, Bull. U. S. Fish Comm., vm, for 1888, 367. JOR- 

 DAN & EVERMANN, Fishes North and Mid. Amer., i, 1183, 1896. 



Range. Galapagos Archipelago. 



Associating with the brown M. olfax, yellow individuals are fre- 

 quently met with exactly resembling the others in all respects except 

 color. It is hence doubtful whether these individuals represent a dis- 

 tinct species or whether they form a chromatic variety of M. olfax. 

 We have such specimens from Wenman, Culpepper, Albemarle, Tagus 

 Cove, and Duncan islands. They are colored in life as follows : 

 Sides of body chrome-yellow, back orange, lower parts lighter lemon- 

 yellow ; head orange-yellow ; fin-membranes chrome-yellow ; iris in 

 some specimens orange, in others carmine. 



The specimen from which Jordan and Bollman described their 

 variety Mycteroperca olfax ruberrima (named ruberrima because 

 supposed by them to have been red in life), is one of these yellow 

 individuals. We have no evidence indicating whether it is a deep- 

 water variety of M. olfax or not. No very young yellow examples 

 nor any of an intermediate or mixed coloration were seen. Along 

 the shore the yellow individuals are not nearly so common as the 

 brown M. olfax, but where the latter was most abundant there occurred 

 the greatest number of M. ruberrima. 



The type of M. ruberima was taken by the Albatross at Abingdon 

 Island, Galapagos, and similar specimens have not been found outside 

 of the Archipelago.
