Hos Hunnen (Tab. VI, Fig. 3,4) danner de ydre 
Kjonsvedheeng en enkelt bagudrettet, poseformig Be- 
holder af meget smal, nesten cylindrisk Form, dog 
gradvis noget tiltagende i Tykkelse mod Enden. 
I sin fulde Udvikling rekker den nesten til Enden 
af nestsidste Halesegment; men er ofte en Del kor- 
tere. Sedvanligvis sees i dens indre et storre eller 
mindre Antal af Ag af morkegron Farve, ordnede 
i 2 eller flere Rader. Enden «uf Aigbeholderen er 
noget koniskt tillobende og bestaar af 2 ved ser- - 
egne Muskler bevegelige Klapper, der begrandser 
en tverliggende spaltformig Aabning, hvorigjennem 
JEggene udstedes. Den ventrale Klap er noget mere 
fremragende end den dorsale og ender med et lidet 
papilleformigt Fremspring (se Tab. VIII, Fig. 11). 
Hos Hannen (Tab. VI, Fig. 1 og 2) er Kjons- 
heengene dobbelte og meget smaa. De udspringer 
(se Fig. 11) hvert med en temmelig bred Basis fra 
Siderne af de 2 Kjonsringe og retter sig skraat 
nedad og bagud. Fortil viser de ner sit Udspring 
en dybt indstikkende Bugt, som begrzendses oventil 
af en sammentrykt trianguler Lap, nedentil af en 
konisk tilspidset Fortsats. Den ydre Del af Ved- 
henget er simpelt cylindriskt, og fra dens stumpt 
tilrundede Ende sees undertiden en uregelmessig 
sagtakket Vorte at skyde frem, egentlig en Udkreng- 
ning af vas deferens. 
Legemet er hos begge Kjon i hoi Grad gjennem- 
sigtigt, saa at de indre Organer, navnlig den med 
rodgult Indhold fyldte Tarmkanal, tydeligt skinner 
igjennem de tynde Integumenter. Farven er noget 
vekslende efter Lokaliteterne, snart meget bleg, 
hvidagtig, snart med et mere eller mindre tydeligt 
redligt eller gronligt Anstrog. 
Beskrivelse af Kroppens Vedheng. 
Qinene (Tab. VI, Fig. 9; Tab. VII, Fig. 1 og 
2, 0), der rager frem til hver Side fra den forreste 
Del af Hovedet, er stilkede og viser idethele en 
meget lignende Bygning som hos Nebalia, skjondt 
deres Bevegelighed er langt mere begreendset. Af 
Form er de nesten kelledannede, idet de gradvis 
udvides mod Enden, der er noget skjevt tilrundet. 
Den egentlige Gienglob, der indtager omtrent 1/3 af 
@iets Leengde, indeholder en oval eller elliptisk An- 
samling af moerkt Pigment, omgivet udad af en klar 
Zone, hvori de ydre lysbrydende Dele af Syns- 
elementerne har sin Plads (se Tab. VIII, Fig. 6). 
Nogen ydre Facettering er ligesaalidt tilstede her 
som hos Nebalia. — Midt imellem Minene sees i det 
Indre af Hovedet en dyb sort Pigmentplet, som er 
det saakaldte Ocellus eller enkle @ie. 
In the female (Pl. VI, figs. 3, 4), the outer sexual 
appendages form a single, bag-formed reservoir 
directed backwards, of very narrow, almost cylind- 
rical shape, but increasing gradually somewhat in 
thickness towards the extremity. In its full develop- 
ment it extends almost to the extremity of the pe- 
nultimate segment, but is often somewhat shorter. 
There is usually seen in its interior a larger or 
smaller number of ova of dark green colour, arranged 
in 2 or several series. The extremity of the mar- 
supium runs somewhat conically out, and consists 
of 2 flaps, moveable by means of peculiar mus- 
cles, which define a transversal fissure-like aper- 
ture through which the ova are expelled. The 
ventral flap is somewhat more projected than the 
dorsal one, and terminates in a small papilliform 
prominence (see Pl. VIII, fig. 11). . 
In the male (Pl. VI, figs. 1 and 2), the sexual 
appendages are double and very small. They issue, 
(see fig. 11), each with a pretty broad base, from 
the sides of the 2 sexual segments and are di- 
rected obliquely downwards and backwards. They 
exhibit in front, near their origin, a deep sinus, 
which is defined above by a compressed triangular 
lobe, and below by a conically pointed projec- 
tion. The outer part of the appendage is plain 
cylindrical, and from its bluntly rounded extremity 
an irregularly serrated nipple is sometimes seen to 
project, really a bulging out of the vas deferens. 
The body, in both sexes, is in a high degree 
transparent, so that the internal organs, especially 
the intestinal canal, filled with red-yellow contents, 
shine distinctly through the thin integuments. The 
colour is somewhat variable, according to the locality, 
sometimes very pale, whitish, sometimes with a more, 
or less distinct reddish or greenish tinge. 
Description of the appendages of the body. 
The eyes (Pl. VI, fig. 9; Pl. VII, figs. 1 and 
2, 0), which project forwards on either side of the 
foremost part of the head, are distinctly peduncul- 
ated, and altogether exhibit a very similar structure 
to those of Nebalia, although their mobility is far 
more limited. They.are almost claviform in shape, 
as they become gradually dilated towards the extre- — 
mity, which is somewhat obliquely rounded. The 
real ocular globe, which occupies about 1/s of the 
eye, contains an oval or elliptical collection of dark 
pigment, surrounded outwards by a clear zone in 
which the outer refracting portions of the visual 
elements have their position (see Pl. VIII, fig. 6). 
Any external facetting is just as little present here 
as in Nebalia. Midway between the eyes there is 
seen, in the interior of the head, a deep black 
pigment-patch, which is the so-called ocellus or 
simple eye.
