FISHES OF WEST COAST OF PERU. 155 



This species is found on the coasts of Peru and Chile. 



As we have no record for the coast of Peru of Gohiesox inar- 

 moratus of Jenyns, included by Abbott in his fishes of Peru, we have 

 omitted it from our list. It is an abundant species to the southward, 

 around Punta Arenas, Tumbes (Chile), Iquique, and the island of 

 Juan Fernandez, and very probabl}^ may be found along the southern 

 coasts of Peru.
