specimens is 5-44 or 45-10. The margin of the spinous dorsal varies in color from 

 dusky to black, but we have some small specimens, collected by the Albatross, in 

 which the fins may be said to be immaculate. 



Our specimens of the young up to 65 mm. in length show light brown cross- 

 bars on back. One at the nape runs obliquely downward and backward to the upper 

 end of gill-opening; one at the front of the spinous dorsal runs obliquely downward 

 and forward to lateral line, nearly meeting the one at the nape; between these there 

 is a shorter vertical bar, and more posteriorly are several bars running downward and 

 forward, which become more or less indefinite along the middle of their lengtli. One 

 or two of these bars are represented by the spots on the upper edge and at the middle 

 of the caudal ^^eduncle. 



Our material from the Atlantic is so meager that we are unable to discuss 

 relationships between E. calif orniensis, E. harengulus, and E. pseudogula.
