Bugkarret tager sit Udspring paa Tarmens Bugside, 
i Niveau: med Ryekarret, er meget fint ved sit Udspring, 
tiltager i Tykkelse paa “den ‘anden (foranlobende) Slynge, 
Fig. 3. n, og afgiver en Mængde Sidegrene til Tarmen, der 
som tidligere nævnt forene sig med Rygkarforgreningerne. 
Mayens Rygkar, der er tykkere end Tarmens, gaar 
‘fortil langs Mave og Svælg og bidrager til i Forening med 
Bugkarret at danne en Ring omkring Svælget, lige bag 
Vandkarringen. Det afgiver Sidegrene, som netformig ud- 
brede sig paa Maven og Svælget, hvor de anastomosere med 
Bugkarrets Forgreninger. Bugkarret er omtrent dobbelt 
saa tykt som Rygkarret, Fig. 3, m, og afgiver lignende 
Grene, som dette. Mavens Bugkar synes at udspringe med 
mange smaa Grene fra Mavens bagerste Ende, hvor denne 
gaar over i Tarmen uden at have nogen direkte Forbindelse 
med Tarmens Bugkar. 
Kjønsorganerne ere fæstede med et meget langt, fast 
og temmelig bredt Ligament til den dorsale Del af Mesen- 
teriet, just paa det Sted, hvor Tarmen begynder, og bestaar 
af to Hovedstammer, der forene sig til en Stamme, som er 
bunden til det ovenneynte Ligament. Den ene Hoved- 
stamme laa imellem Tarmbugtningen, uden at være bunden 
til denne, flotterede frit i Kropshulheden, og var den største, 
Fig. 3, 0; den dannes af et rundt, hult Rør, hvorfra udgaa 
mange temmelig korte Grene, 4—6, der ere forsynede med 
Smaablærer, saaledes at altid Enden af Grenen er delt i, 
to, Fig. 3, p. Den anden Hovedstamme er kortere og fat- 
tigere saavel paa (rene som paa Blærer, og var ved sin 
-ydre Ende bundet til Kropsvæggen tæt ved Stenkanalens 
Befæstning ved en temmelig lang Bindeveeystraad. 
Efterat begge Stammer have forenet sig til en fælles 
Stamme, gaar denne slangeformigt og skjært forover imod 
Stenkanalen, hvor den fester sig til dennes Mesenterium, 
følger den et Stykke Vei, men skiller sig atter fra den for 
at munde ud noget bagenfor to af Rygtentaklerne, Fig. 2, b. 
Den fælles Udførselskanal er især paa den forreste Del, 
hvor den gaar langs Stenkanalen, meget fast og har en 
hvid glindsende Farve. Den indre Flade af Blærerne er 
beklædt med Celler, hvori Æg saaes i forskjellige Udvik- 
lingsstadier. Det er sandsynligt, at Kjønnet er adskilt, 
ligesom hos Elpidia og Kolga; det Exemplar, vi have havt 
til vor Raadighed, var en Hun; der var Intet, som tydede 
hen paa blandet Kjøn. 
Nervesystemet afviger neppe fra hvad der er almin- 
deligt for Holothuriderne. Vi have seet én Nervering, der 
er temmelig smal, som omgiver den forreste Del af Svælget 
strax bagenfor Mundskiven. Fra den udgik fine Grene til 
Svælget og Mundskiven, ligesom enkelte større Stammer 
gik over paa den indre Flade af Kropshuden imellem denne 
og Længdemusklerne (1 for hver Længdemuskel), uden at 
The yentral vessel originates on the ventral surface 
of the intestine, in a plane with the dorsal vessel, is ex- 
ceedingly slender at its commencement, increasing in thickness 
on the second convolution, fig. 3, mn, and sending off numer- 
ous lateral branches to the intestine, which, as already 
stated, unite with the: ramifications of the dorsal vessel. 
The dorsal vessel of’ the stomach, which is thicker 
than, that of the intestine, takes a forward course, 
ing along the stomach and the gullet, and contributes, 
together with the ventral vessel, in forming a ring round 
the gullet, immediately posterior to the water-vascular ring. 
It sends off a number of lateral branches, which spread 
over the stomach and the gullet as a vascular network, the 
ramifications anastomosing with those of the ventral vessel. 
The ventral vessel is almost as thick again as the dorsal 
vessel, fig. 3, m, and branches in a similar manner. The 
ventral vessel of the stomach would seem to have its origin 
pass- 
in numerous branchlets proceeding from. the posterior ex- 
tremity of the stomach, where the latter opens into the 
intestine, without however being directly connected with the 
ventral vessel of the intestine. 
The generative organs are attached to the dorsal por- 
tion of the mesentery by an exceedingly long, rather broad, 
and close-textured membranous ligament, at the exact point 
where the intestine commences, and consist of two trunk- 
like appendages, coalescing into one, which is webbed to 
the membranous ligament. One of these stems lay within 
the intestinal convolution, but was not attached to it, — 
floating freely m the mperivisceral cavity; this was the 
largest, fig. 3, 0; it consists of a tube, from which proceed 
numerous branchlets, from 4 to 6, furnished with vesicles, 
in such manner that the extremity is always fureate, fig. 
3, p.. The other stem is shorter, and less abundantly 
provided alike with branchlets and vesicles; at its outer 
extremity it was connected with the wall of the body, close 
to the point of attachment of the sand-canal, by a rather 
long filament of connective tissue. 
The common: trunk produced by the junction of the 
two stems, winds obliquely forward to the sand-canal, with the 
mesentery of which it is connected, accompanies it a short 
distance, whereupon it. strikes off, to disembogue a little 
posterior to two of the dorsal tentacles, fig. 2, b. The 
common excretory canal. more especially the anterior por- 
tion, which passes along the sand-canal, is exceedingly 
firm in texture, and of a lustrous white. - The inner surface 
of the vesicles was clothed with cells, containing ova in 
divers stages of development, The sexes are most pro- 
bably separate, as in Elpidia and Kolga. The specimen 
here described was a female; we could detect no feature 
suggestive of bisexual organisation. 
The nervous system will hardly be found to differ 
from that in other Holothurians. 
ring, rather slender, surrounding the anterior portion of 
the gullet, immediately posterior to the oral disk. From 
its outer margin a number of delicate ramifications pro- 
ceeded to the gullet and the oral disk; and several 
larger branches were sent off to the inner surface of the
