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.
