2. Munna limieola, G. 0. Sars.
(PI. XLV, fig. 1.)
Munna limieola, G. O. Sars, Beretning 0111 en i Sommeren 1865 foretagen zoologisk Beise ved
Kj'sterne af Christianias og Christiansands Stifter, p. 29.
Specific Characters. Body
of female somewhat less robust than in the
type species, with the anterior division oval in form. Ocular processes very much
projecting. Caudal segment rather large, nearly equalling the mesosome in length,
and oval pyriform in shape, lateral edges evenly curved, and without any den-
ticles, but clothed with scattered bristles, tip without any serrated lamellae. Eyes
comparatively smaller than in M. BoecM, and narrowly rounded. Superior antennae
reaching to the middle of the penultimate peduncular joint of the inferior ones, flagel-
lum 5 -articulate, last articulation, as usual, extremely small. Inferior antennae twice
the length of the body, flagellum much shorter than the peduncle. Legs greatly
increasing in length posteriorly, and far less strongly built than in M. BoecJci;
1st pair with the carpus but slightly widening distally, and nearly as long as the
propodos; last pair considerably exceeding the body in length, and having the
carpal joint rather narrow, propodal joint extremely slender, being
almost twice
as long as the former. Uropoda nearly as in the type species. Colour uniformly
pale yellowish grey. Length
of adult female 3 mm.
Remarks. Though rather nearly allied to M. Boecki, this species may, on
a closer examination, be easily distinguished by its less robust body, the smaller
eyes, the form of the caudal segment, and the absence on it of lateral denticles
and apical serrated lamell*, and finally, by the extremely slender and elongated legs.
Occurrence. This species occurs not infrequently both off the south and
west coasts of Norway, from the Christiania Fjord, at least to the Lofoten Islands.
It is only found in greater depths, ranging from 60 to 300 fathoms, on muddy
bottom. Out of Norway, it has not yet been recorded.
3. Munna Fabricii, Kroyer.
(PL XLV, fig. 2.)
Munna Fabricii, Kroyer, Nat. Tidsskr. Bd. 11, p. 380.
Specific Characters. Body rather short and compact,
with the anterior divi-
sion rounded oval in outline. Ocular processes rather thick, and less prominent
than in M. limieola. Caudal segment oblong oval, but slightly narrowed behind,
lateral edges evenly convex, and each armed in front with a single slender den-
ticle; apical lamellae distinctly serrated. Eyes rather large, semi-globose. Supe-
rior antennae scarcely reaching to the middle of the penultimate peduncular joint
