This species belongs to the more southern Chilean fauna, but 



Valenciennes is authority for the statement (ix, 400) that it is a 



common market fish at Lima from May to July, and hence may 



be considered to range from Peru to Patagonia (Jenyns).

 tic coast, U. S.].

 Addenda, p. 2835. 



Although there are no specimens of this species in the Beardslee 



collection, yet we have identified some taken 6° south of the equator 



in the East Pacific by the U. S. S. " Albatross," and it may be 



considered to be within the limits of Peruvian waters.

The fish described by Jenyns as Exoca:ius exiliens Bloch without 

 doubt belongs to this species.
