the carpal one. dactylus minute; the 3 succeeding pairs rather slender, though
scarcely exceeding the body in length, dactylus very long and slender; 2nd pair
somewhat more strongly built in male than in female, with the carpal joint slightly
dilated. Natatory legs with the propodal joint broadly oval, much constricted at
the base, dactylus narrow, styliform. Uropoda extremely small, outer ramus
scaively half as large as the inner. Colour of dorsal face very dark fuscous,
towards the edges of the segments almost black. Length
of adult female 1 1

Remarks. This species may be easily distinguished from the preceding
ones by the broad, obtusely rounded frontal part of the cephalon, and by the
very
dark colour of the dorsal face. It is also rather inferior in size.
Occurrence. I first found this form in the inner part on the Christiania
Fjord, and have subsequently met with it in many other places of the Norwegian
coast, and as far north as Bodo. It is not strictly a deep-water species, being
often found in only a few fathoms' depth among alga?. Its swimming motions
are extremely rapid, and are effected by long abrupt bounds backwards. Out of
Norway this form has not yet
been recorded.
