Centralnervestrængen bestaar af en tyk muskuløs Skede, 
Fig. 14, 7, imdenfor hvilken den egentlige Nervemasse ‘er, 
som dannes af et ydre celluløst Lag, Fig. 14, kh, som er 
det bredeste, og et indre tibrillært, Fig. 14, 7, der ligesom 
omgiver Centralkarret. Imellem Cellerne og Fibrillerne er 
et fint Bindevæv, der kitter Elementerne sammen og som 
udgaar fra Skedens indre Flade. Paa den forreste Del af 
Spiserøret tabte Nervestrængen sig 1 ramolleret Væv, saa 
vi ikke kunne afgjøre, hvorvidt den danner nogen Svælg- 
ring, hvilket dog er det sandsynligste; thi i Snabelen for- 
længer den sig ikke, — det have vi overbevist os om baade 
ved Tver- og Fladesnit. 
Hyad Blodkarsystemet angaar, saa kunne vi Intet 
derom meddele, da vi ikke have fundet Spor dertil paa 
Grund af den slette Konservation. 
Langs den forreste Halvdel af Tarmens Bugflade og 
bundet til Mesenteriet saaes .et baandformigt, langstrakt 
Organ, der syntes at være dannet af sæktormige Udbugt- 
ninger, og hvori kunde iagttages Cellegrupper, der tydede 
hen paa en begyndende Ægdannelse.

Paa høire Side af Tarmen i Kropshulhedens forreste 
Del fandtes et langt, næsten cylindrisk Organ, hvis forreste 
noget smalere Del var fæstet til Bugen; og Tilheftnings- 
stedet svarede til det Sted, hvor der udvendig paa Kroppen 
saaes den førbeskrevne Aabning.

Lige ved Tilheftningsstedet paa Organets undre Flade 
saaes en Forlængelse, der sandsynligvis var den tragtformige 
Aabning for Æggebeholderen, 
for at være; men da vi nærmere vilde undersøge denne 
Forlængelse, viste det sig at Veevet var saa ramolleret, at 
vi ikke vove med Sikkerhed at antage den for Tragten. 
Det langstrakte Organ, Fig. 11, f, havde en afrundet 
fri Ende; men var forresten unde? til Kropsvæggen ved 
flere fine Bindeveeystraade. Vi fandt intet Indhold i dette 
Organ.  Væggene vare muskuløse,

The central nervous chord consists of a thick mus- 
cular sheath, fig. 14, 7, underneath which lies the true 
nervous substance, consisting of an outer cellular layer, fig. 
14, k, comparatively broad, and of an inner fibrillous layer, 
fig. 14. 7, surrounding, as it. were, the central vessel. 
Between the cells and the fibrils extends a layer of delicate’ 
connective tissue, uniting the several elements, and which 
issues from the inner surface of the sheath. On the an- 
terior portion of the cesophagus the nervous chord was lost 
in a layer of disintegrated tissue, and we could not therefore 
determine whether it forms an pharyngeal ring, which, 
however, it most probably does; for it is not produced into 
the proboscis; of this we: are assured from a careful ex- 
amination both of transverse and longitudinal sections. 
As regards the circulatory .system (blood vessels) we 
have nothing whatever to communicate, not having found so 
much as a trace thereof in the badly preserved specimens. 
Along the anterior half of the ventral surface of the 
intestine, and webbed to the mesentery, was seen a riband- 
shaped, elongate organ, consisting apparently of a series of 
sac-like dilatations, and in which groups of cells could be 
distinguished having the appearance of developping ova. 
We regard this organ as an ovary. 
On the right side of the intestine in the anterior por- 
tion of the perivisceral cavity, protended a long, almost 
cylindrical organ, with its anterior, somewhat slenderer, part 
webbed to the belly, the line of attachment corresponding 
to the place on the outer surface of the body in which was 
seen the fore-described opening. | 
Close to the line of attachment on he inner surface 
of the organ, was an elongated prolation, most probably the 
funnel-shaped opening to the uterine pouch, which we take 
the said organ to be; but on proceeding to: a closer ex- 
amination, the tissue proved so completely disintegrated 
that we dare not regard it as the funnel. 
The: elongate organ, fig. 11, f, had a rounded free 
extremity, but was webbed to the wall of the body by 
numerous delicate filaments of connective tissue. This or- 
gan we found to be void of contents. The walls were 
muscular, but had fallen in, and crumbled to the touch. 
The perivisceral fluid was observed in the proboscis 
only, and it contained numbers of almost discoid cells, 
pale brownish-yellow in colour.
