and last segments of mesosome scarcely more than half as long
29
as the others.
Metasome slightly dilated, and scarcely longer than the last 2 segments of meso-
some combined, terminal segment of medium size, and obtusely rounded at the
tip. Superior antennae with the basal joint
much shorter than the other 3 com-
bined, 2nd joint comparatively large, equalling in length the outer 2 taken
together. Chelipeds not very strong, with the hand subtriangular
and about the
length of the carpus. Pereiopoda comparatively small, basal joint of the 3 pos-
terior pairs considerably tumefied. Uropoda attaining half the length
of the
metasome, inner ramus slender, Inarticulate, outer one represented only by a
small knob-like projection of the basal part, carrying 2 slender seta!. Length
2.70 mm.
Remarks. This form, likewise first described by Prof. Lilljeborg, is
easily recognized by its extremely slender, almost filiform body, and by the
apparently single-branched uropoda.
Occurrence. I have met with this species occasionally in several places
on the south and west coasts of Norway, from the Christiania Fjord up to Kvalo
on the Nordland coast, in depths ranging from 3(3 to 100 fathoms.
Distribution. Bohuslan (Lilljeborg), Oresund (Meinert).

Characters. 9 Body slender and elongated,
about 10 times
as long as it is broad, with the cephalosome only narrowed in its most anterior
part. First and last segment
of mesosome about same size and shorter than
the others, which are fully as long as they are broad. Metasome rather large,
considerably longer than the last 2 segments of mesosome combined, and also
somewhat broader, terminal segment we'll developed, occupying more than Y* f
the metasome and obtusely rounded at the tip. Superior antenna of the usual
structure, 2nd joint not quite as long as the outer 2 combined. Chelipeds not
very large, hand shorter than the carpus, subtriangular, fingers not attaining the
length of the palm. Pereiopoda comparatively small, basal joint of the 3 posterior
pairs less tumefied than in L. filiformis. Uropoda about the length
of the ter-
minal segment of metasome, inner ramus well developed, Inarticulate, with the
last joint rather short, outer ramus represented by a. rather strong, mueroniform
