Coimuon ; about a dozen specimens are in our collection. 



We have coiui)ared these with specimens from Havana and Panama, 

 and find that some specimens have six rows of scales on the cheek and 

 no notch in the preopercular margin ; others show seven, eight, and ten 

 rows of scales on the cheek and a more or less evident angle in the 

 margin of the jireopercle {radiale). 



All of our specimens are some lighter, and the caudal spot is more 

 l)ronouuced than in the Havana specimen, and are also a little lighter 

 than those from Panama. 



Six of our Guaymas specimens measure as follows:

This is an abundant fish in this locality, and is perhaps the most im- 

 portant food tish found here.
