* A very doubtful species, which may be the yoxmg of Sehastes marinus, with an ab- 

 normal number of spines, is accredited to our Atlantic coast, viz : 

 S.f fasciatus (Storer. ) 



"Body elongated, not convex in front of dorsal fin as in Sehastes norvegicus ; four 

 distinct dark brown tijansverse bands upon the sides, the broadest at the posterior 

 portion of the body." D. XIII-14; A. Ill, 7. Provincetowu, Mass. (Storer.)
