ende Paxiller, Fig. 8, g, der senere skulle omtales. Skaf- 
tet paa de 5 Analpaxiller er meget tykt, kort og har en 
bred, halvrund, spatelformig Ende, Fig. 8, d, hvis indre 
Flade, som er lidt konkav, er Fæstepunktet for en stærk 
Muskel, og hvis ydre Flade er glat, lidt konvex og 
hvis halvrunde Rand bærer to Rækker Kalknaale, der 
ere stillede i en Halvkreds, Fig. 8, h. I den ydre Række 
er der 6—8 temmelig korte Naale, men 1 den indre er der 
8—10 meget lange Naale, til hvis Grunddel den tidligere 
omtalte Muskel tæster sig. Disse lange Naale ere vifte- 
formigt forenede med en tynd Membran og danne saaledes 
Trakten, som lukkes og aabnes efter Omstændighederne.

Grund 2 Paxiller, Fig. 7, g. 8, 2, altsaa i det Hele 10, 
som krandsformig omgive de forste. Disse 10 forste Arm- 
paxillers Basaldel bestaar af 3 Rødder, af hvilke den in- 
derste, Fig. 8, er kortest, tykkest og stoder umiddelbart 
til en af de ydre Rodder paa de 5 Analpaxiller, Fig. 8, f, 
saaledes nemlig, at disses to ydre, meget lange Rød- 
der støtte sig til de to første Armpaxillers indre Rod, Fig. 
8, f, k. Disse Armpaxillers ydre Rødder, Fig. 8, 1,1, ere 
lange, smale og krumme, saa at de tilsammen danne en 
Bue, Fig.7,h.8,m, forlænge sig nedad og til Siderne, hvor 
den ene udvendige, nærmest Interbrachialrummet, Fig. 8, I, 
fæster sig til den underste Proces af de øverste Interbrachi- 
alplader, Fig. 8, , imedens den anden, indre Rod gaar: 
henimod Midten af Søstjernens Arm, hvor den forener sig 
med den tilsvarende Rod fra den modsatte Side, Fig. 8,0. 
Skaftet paa de første Armpaxiller har samme Form og 
Længde som paa Analpaxillerne, kun er det lidt fla- 
dere og meget tyndere, og paa den brede, frie Ende, der 
danner en aflang Kreds af smaa, runde Artieulationsflader, 
sidde i en aflang Krands 7 (4 lange og 3 korte) artikule- 
rende Kalknaale, Fig. 8, p, der vifteformigt udbrede sig i 
Skivens ydre Ryghud, Fig. 1, 0. 
Lige under de ovenfor beskrevne øverste Interbrachi- 
alplader findes 5 andre (undre) Interbrachialplader, der 
ere noget brede, udhulede og bøiede efter Længden, Fig. 
9, d. Fra deres øverste Ende udgaa 3 Processer, en til 
hver Side, Fig. 9, e, og en i Midten, Fig. 9, f. Sidepro- 
cesserne gaa opad og udad og forene sig med de inderste 
Processer fra de 5 øverste Interbrachialplader, Fig. 9, c,

fig. 8, d) of which, the inner ones (PI. XIII, fig. 8, e) 
radiating towards the anal area, rest on the processes 
named, and almost connect with the basal parts of the 
paxillæ of both the adjoming margins (Pl. XIII, fig. 7); 
whilst, the outer roots (Pl. XIII, fig. 8,/), abut on the 
roots of two paxillæ below (exterior) (Pl. XIII, fig. 8, 9), 
which will subsequently be referred to. The shaft of the 
five anal paxillæ is very thick and short, and has a broad 
semicircular spatulate extremity (Pl. XIII, fig. 8, d), whose 
inner surface is slightly concave, and forms the insertion 
for a strong muscle; and whose outer surface is smooth 
and slightly convex; 
; and, finally, whose semicircular margin 
carries two series of calcareous needles, arranged in a 
semicircle (Pl. XIII, fig. 8, h). 
In the outer series, there are 6—8 rather short need- 
les, but in the inner series, there are 8—10 very long 
needles; in whose base, the muscles previously spoken of 
are inserted. These long needles are fan-shaped, and un- 
ited by a thin membrane, forming, thus, the funnel, which 
is capable of closing, or opening, according to circum- 
stances. 
A little below the five anal paxillæ, two paxillæ (PI. 
XIII, fig. 7, g. 8, 2) are seen at the origin of each ray; 
therefore, ten altogether. These latter, surround the former, 
The basal part of these ten first brach- 
ial paxillæ, consists of three roots, of which, the inmost 
root (fig. 8) is the shortest and thickest, and abuts, immed- 
iately, upon one of the exterior roots (Pl. XIII, fig. 8,7) 
of the five anal paxillæ; in such a manner, that their two 
exterior, very long roots, butt with the inner root of the 
two first brachial paxille Pl. XIII, fig. 8, f,/). The ex- 
terior roots ef these brachial paxillæ (Pl. XIII, fig. 8, 7, 7), 
are long, narrow, and curved; so that, together, they form 
an are (Pl. XIII, fig. 7, h. 8, m). They become elong- 
ated downwards, as well as laterally, and one of them (the 
exterior one, next the interbrachial space (Pl. XIII, fig. 
8, e), unites with the inferior process of the superior inter- 
brachial plates (Pl. XIII, fig 8, m) whilst, the second one 
(inner one) approaches towards the middle of the rays of 
as with a wreath. 
the starfish; and there, unites with the corresponding root 
of the opposite margin (PI. XIII, fig. 8,0). The shaft of 
the first brachial paxille, has the same form and length, 
as that of the anal paxille, but, it is slightly flatter and 
much thinner, and upon it’s broad free extremity, which 
forms an oblong ring of small circular articulatory surfaces; 
there sits, an oblong wreath, consisting af 7 articulated 
calcareous needles (4 long ones and 3 short ones) (PI. 
XIII, fig. 8,p) which spread in a fan-shape, in the outer 
dorsal integument of the disk (Pl. XIII, fig. 1, 0). 
Immediately under the above described superior in- 
terbrachial plates, five other (inferior) interbrachial plates 
are found. These last, are somewhat broad, hollowed, and 
curved lengthwise (Pl. XIII, fig. 9, d). From their sup- 
erior extremity, three processes proceed; one to each lat- 
eral margin (Pl. XIII, fig. 9, e), and one in the middle 
(Pl. XIII, fig. 9, f). The lateral processes extend up- 
wards and outwards, and unite with the immost processes
