FISHES OF WEST COAST OF PERU. 125 



rior margins of scales olive green, centers light and tinted red ; two 

 black stripes of somewhat irregular outline on sides (^ cm. wide in 

 specimen 18.5 cm. long), the lower extending from lower part of 

 eye to a point halfway between posterior limit of dorsal and anal 

 and the posterior limit of scales on the caudal ; the other from mid- 

 dle of eye upwards a little and then parallel to the other stripe and 

 at a distance from it of 1 cm. to dorsal margin of peduncle; two 

 black spots on scaly part of base of caudal placed symmetrically 

 above and below lateral line; usually an orange spot between end of 

 stripe and the black spot ; dorsal, proximal, and ventral parts of caudal 

 reddish, otherwise tinted with gold; dorsal and anal fin rays large- 

 tipped with blue and purple; extreme posterior parts of both fins 

 below longest fin rays with mixed red and gold; pectoral reddish; 

 ventrals purplish ; iris golden posteriorly, red anteriorly ; skin cover- 

 ing jaws red posteriorly. 



The coloration and form of this species are subject to considerable 

 variation. In the adult male there is a large fleshy pad on the fore- 

 head, this often reaching a height of several times the diameter of 

 the eye ; this pad said to be much less pronounced in the female. 

 In the young the snout is pointed and the caudal truncate. 



This species occurs along the coast of tropical America, Galapagos 

 Island southward to Peru.
