82 BRITISH OOPEPODA. 



racters of the second and third pairs of feet in the 

 male, amply suffice to distinguish this from all other 

 species ; it is also much shorter and stouter than any 

 other known to me, having indeed, at first sight, more 

 the appearance of Dactylopus than of Laophonte. The 

 second and third feet of the male show an approach 

 to the structure of those limbs in Harpacticus ; and it 

 would seem almost desirable, on this ground, to esta- 

 blish a new genus for the reception of this species.

Body more slender than in the preceding species ; 

 margins of the segments smooth; caudal segments 

 long and slender, about twice as long as the last 

 abdominal joint (Plate LXXIV, fig. 15). Anterior 

 antennse (Plate LXXYI, fig. 10) rather short, 7- or 8- 

 jointed, first three joints much longer than the fol- 

 lowing four or five, the relative lengths being as
