 Scomber omorus sierra Jordan & Starks 



This species is the Pacific Coast representative of the Spanish 

 mackerel which it very closely resembles and from which it differs 

 only in the more posterior insertion of the soft dorsal and in the 

 colouration. It is known only from Mazatlan, reaches a length 

 of 2\ feet, and is not highly valued as food, but why it is 

 not we are unable to say. 



Colour, silvery, dark steel-blue on the back; sides with nu- 

 merous round spots of the same colour as the back, 3 rows 

 below and i above the lateral line; spinous dorsal all black; 

 anal white; posterior surface of pectoral entirely black, anterior 

 yellowish with blackish borders; caudal black. A large example, 

 probably a male, had 5 rows of spots below lateral line, these 

 spots decreasing in size anteriorly toward the belly, but extending 

 nearly to base of ventral fin.
