A REVIEW OF THE MYSIDACEA 



53 



The antennal scale (fig. 10, b) extends somewhat beyond the distal 

 end of the antennular peduncle. It is about three times as long as 

 broad, with the outer margin straight and terminating in a strong 

 spine beyond which the apex of the scale barely projects.
