 species, the palm of the first gnathopods does not slope away 

 from the base of the claw (dactylus), but forms nearly a right 

 angle with the sides of the propodos.

 St Monans with a tow-net, close to the bottom, in November 

 1904. In this species the eyes are of a light cream colour or

 a row of very minute spines extending along its dorsal aspect
