synes at dannes af concentriske Ringe, som omgive en aflang 
Fordybning, der har en smuk vinrød Farve, og hvori tildels 
findes flere smaa, lysbrydende Korn, Fig. 9. De have en 
Længde af 0.0138”. Disse elliptiske Legemer findes meget 
udbredte i Vævene, hvor der forøvrigt ingen Kalk findes, 
- saaledes i Mundskivens og Rygpapillernes Bindeveev, i Peri- 
toneum ete. 
Imedens Kroppens Hud er temmelig fattig paa Kalk, 
. er det modsatte Tilfældet med Fodder og Tentakler. Fød- 
derne, der langs Siderne sidde ligeoverfor hverandre, Fig. 
1,2, danne stive cylindriske Rør, i hvis Bindevæv findes 
en stor Mængde Kalkspikler, som ligge tæt paa hverandre 
og kredsformig omgive Foden, lig en Filegrans Kalkkapsel. 
Indenfor Bindevævslaget er en Muskelhud, som bestaar af 
Ring- og Længdefibre, og til denne er ved et fint Bindevæv 
fæstet den Sidegren af Vandkarsystemets Længdekar, som 
gaar ind i Foden. 
De Kalkspikler, som findes i Fødderne, ere noget 
forskjellige fra Hudens. De ere meget større, have en 
Længde af 0.6147” og en Bredde af 0.041", ere mere 
eller mindre krumbøiede, stundom dog ganske lige, og ere 
besate med en stor Mængde Takker, der ofte, især i begge 
Ender, staa saa tætte, at Spiklerne faa Udseende af at 
være saugtakkede, Fig. 10. Paa enkelte Spikler udgik fra 
Midten en stærk Arm, der endte ganske spids, og selv 
denne Arm var temmelig takket. Paa Enden af Foden, 
der er konisk, men som kan afplaneres, er ingen Kalkskive: 
men her findes flere mindre Kalkspikler, som hjælpe til at 
danne Hvælvet af den hule Keele, Fig. 12. Forøvrigt 
findes i det indre Lag af Bindevævet ogsaa de tidligere 
omtalte elliptiske Kalkskiver. Fødderne kunne ikke ind- 
trækkes i Legemet, heller ikke synderlig forkortes, derimod 
kunne de bevæges i forskjellige Retninger, og dette sker 
da ved deres Grunddel, hvor Kalkspiklerne ere i ringere 
Mængde tilstede. 
Tentaklerne ere omkring 3”” lange, hvoraf Skaftet 
udgjør omtr. 2””. og Bladet 1””. Skaftet er cylindrisk, 
lidt fladtrykt mod den adorale Side, Fig. 13, a, og dannes, 
foruden af sin Cuticula og Epithelet, af et temmelig fast, 
tykt Bindevævslag, hvori enkelte smaa Kalkspikler og de 
elliptiske Kalklegemer ere leirede; indenfor Bindevævslaget 
er en Muskelhud, som bestaar af Ring- og Længdemuskler, 
og til denne Muskelhud er Tentakelkarret bundet ved et 
tyndt Bindeveevslag, 
af Tentakelen bestaar af 5 Forlængelser, Fig. 13, b, der 
hver har i Regelen 3 Indskjæringer, Fig. 13, c, hvorved 
enhver Forlængelse bliver tredelt (trelappet), saaledes nem- 
lig, at den midterste Lap er den største, Fig. 13, d. Hele 
denne haandformige Del med samtlige Forlængelser og 
Lapper ere overordentlig rige paa Kalkspikler. De danne 
her ved deres Sammenfletninger smukke Kalkpantsere og 
Den bredere eller haandformige Del 
central, composed apparently of concentric rings, circum- 
scribing an oblong excavation, of a fine vinous colour, in 
which oceur here and there several minute refractive gran- 
ules, fig. 9. They have a length of 0.013”. These ellip- 
tic corpuscles are particularly numerous in the tissues, 
where there is no calcareous deposit, — for instance in the 
connective tissue of the oral disk and of the dorsal papillæ, 
in the peritoneum, &c. 
The skin of the body appears on the whole rather 
sparingly furnished with calcareous deposit, whereas . the 
reverse is the case with the suckers and tentacula. 
The lateral suckers, arranged in opposite rows, figs. 1, 2, 
constitute stiff cylindric tubes, exhibiting in their connective 
tissue a large number of calcareous spicule, crowded 
together, and encircling the sucker as with a calcareous 
fiigrane capsule. Underneath the layer of connective tis- 
sue extends a muscular tunic, composed of annular and 
longitudinal fibres, a thin connective membrane webbing to 
this integument the lateral branch of the longitudinal vessel 
of the aquiferous system, which is prolonged into the sucker. 
The calcareous spiculæ in the suckers differ slightly 
from those in the integument of the body. They are much 
larger, measuring 0.614”” in length and 0.041” in breadth, 
more or less arcuate, — here and there however quite rec- 
tilinear, — and furnished with a large number of dentelli, 
which in places, more particularly at both extremities, are 
so densely disposed as to give the spicule a serrated ap- 
pearance, fig. 10. From the middle of some of the spiculæ 
proceeds a strong prolation, terminating in a sharp point, 
and this even was'to a considerable extent indented. At 
the extremity of the sucker, which is conical in form, but 
the apex of which can be depressed, leaving a plane surface, 
there is no calcareous plate; but here occur divers smaller 
spiculæ, which help to build up the vaulted summit of the 
hollow cone, fig. 12. For the rest, the elliptic calcareous 
plates also occur in the inner layer of connective tissue. 
The suckers cannot be retracted into the body, nor are they 
to any considerable extent contractile; they admit however 
of being freely moved about in different directions, the 
motory power proceeding from the basal extremity, where 
the calcareous spicule are less numerous. 
The tentacles are about 3”” in length, the shaft 
measuring 2”” and the pinna 1””. The shaft is cylindric 
in shape, slightly depressed on the adoral side, fig. 13, a, 
and composed, exclusive of the cuticle and the epithelium, 
of a layer of connective tissue, comparatively thick and 
frm in texture, through which are dispersed a few 
minute calcareous spiculæ and the elliptic calcareous cor- 
puscles. Beneath the layer of connective tissue extends a 
muscular integument, consisting of annular and longitudinal 
muscles; and to this muscular integument the tentacular 
vessel is webbed by a thin layer of connective tissue. The 
broader or palmate portion of the tentacles consists of 
5 pinnæ, fig. 13, b, each of which, having as a rule 3 in- 
cisions, fig. 13, ¢, is accordingly trifid (three-lobed), the 
middle lobe being the longest, fig. 13, d. The whole 
of this palmate portion, including the pinne and their
