Pedicellarier ere temmelig store i Forhold til Søstjernens 
Størrelse. Basaldelen er bred, den underste Rand stærkt 
krummet; Apophyserne stærke og temmelig fremspringende, 
Tab. III, Fig. 10,a. Kjæverne ere smale, noget afstum- 
pede i den fri Ende og meget brede, idet de gaa over i 
den forlængede Del, Fig. 10,0. Den ydre Flade er meget 
konvex og forsynet paa dens ydre halve Del med tætstaa- 
ende Vacuoler, Fig. 10,c. Den indre Flade er lidt kon- 
kav, og saavel dens øverste som nederste Del er besat med 
flere Rækker stærke Tænder, Fig. 11, a. Den forlengede 
Flade 
Del af Tangen er meget bred og er paa den ydre 
af den afrundede Ende riflet, Fig. 11,5. 
De lige Pedicellarier, som hverken Sars eller Norman 
har iagttaget, staa enkeltvis og langt fra hinanden langs 
Ambulacralfuren, lige ved Grunden af den indre Ambula- 
eralpig. Basilardelens undre Rand danner en stump Vin- 
kel, den øvre Rands Midtparti en liden Fremstaaenhed, og 
paa hver Side af denne er en liden, rund, konkav Ledde- 
flade, Fig. 12. 13,a.  Kjæverne ere langstrakte; deres 
øverste, frie Ende er tilspidset og noget krumbøiet indad; 
deres nederste, brede Del gaar over i en konisk Forlæn- 
gelse, paa hvis runde Ende findes en Leddeflade, der arti- 
kulerer med Basilardelen. Deres ydre Flade er kun lidet 
konvex og frembyder et netformigt Udseende med temme- 
lig tætte Masker, der staa i Længderækker, Fig. 12.13,0. 
Deres indre Flade er konkav og fornemmelig langs Ran- 
dene tæt besat med uregelmæssige, kortere eller længere 
Tænder, Fig. 12, c. 
Sars angiver 1 sin første Afhandling over Asterias 
Miilleri (Fauna littoralis Norvegiæ, Iste Hefte), at ,de saa- 
kaldte Furepapiller danne 2—3, noget uregelmæssige Ræk- 
ker.“ I hans senere Arbeide over Norges Echinodermer 
siger han, at Astertas Miilleri egentlig ikke har mere end 
en Række Furepapiller, den anden og tredie Række, som 
han tidligere antog for Furepapiller, er ikke saadanne, 
men Pigge, der tilhøre Hudskelettet. 
Ifølge vore Undersøgelser har Asterias Miilleri virkelig 
to Rækker Furepapiller, hvoraf den ydre Række, hvis Pigge 
ere noget kortere end de 1 den indre Række, faar et no- 
get uregelmæssigt Udseende derved, at Papillerne staa læn- 
gere fra hverandre. Det forholder sig nemlig saaledes, at 
i Regelen er hveranden Adambulacralplade forsynet med 
2, hveranden med 1 Papille. Dog hænder det, at der kan 
vere 2—3 Adambulacralplader efter hinanden, der hver 
kun bærer en Pig; men dette hører til Undtagelserne. 
Asterias gronlandica, St., med hvilken man har villet 
identificere Ast. Miilleri, har de samme to Former af Pe- 
dicellarier, som ovenfor ere beskrevne og adskiller sig i 
ingen Henseende fra dem.

with pedicellariæ on their external basal halves. These 
cruciform pedicellariæ are rather large in proportion to 
the size of the starfish, The basal portion is broad, and 
the inferior margin, is much bent, with the apophyses strong, 
and rather protuberant (pl. III, fig. 10, a). The jaws are 
narrow, and somewhat blunted at the free extremity, also, 
very broad, at the point where they enter upon the elonga- 
tion (fig. 10, 6). The external surface is very convex, 
and on the exterior half, it is furnished with close-set vac- 
uola (fig. 10,¢). The internal surface is slightly concave, 
and both its superior and inferior portions, are beset with 
several. series of strong teeth (fig. 11, a). The elongate 
portion of the forceps is very broad, and striated on the 
exterior surface of the rounded extremity (fig. 11, 0). 
The rectiform pedicellariæ; which have been observed 
by neither Sars nor Norman; are placed singly, and at 
long intervals from each other, along the ambulacral fur- 
row, Close to the base of the imner ambulacral spike. The 
inferior margin of the basillar part forms an obtuse angle. 
On the superior mesial margin, a small protuberance oc- 
curs, and upon each lateral surface of this, there is a 
small, circular, concave, articulatory surface (figs. 12, 13, a). 
The jaws are elongate, with the superior free extremity 
acuminate, and somewhat curved inwards; their inferior, 
broad portion, passes over into a coniform elongation, on 
the round extremity of which, there occurs an articulatory

Sars states in his first paper on Asterzas miillert (Fauna 
littoralis Norvegiæ, Iste Hefte) that “the so-called furrow- 
”papillæ form 2—3 somewhat irregular series’. In his 
later work upon Norway’s Echinodermata, he says, that 
Asterias miilleri has not, really, more than one series of 
furrow-papillæ; the second and third series, which he prey- 
iously supposed to be furrow-papillæ, not being so; but 
spines, pertaining to the dermal skeleton. 
According to our researches, Asterzas miiller: has really, 
two series of furrow-papille, of which, the exterior ser- 
ies, whose spines are somewhat shorter than those of the 
inner series, has a somewhat irregular appearance, owing 
to the papillae being placed further apart from each other. 
The fact is, that usually, the ambulacral plates are fur- 
nished with 2, and 1, papilla alternately. It happens how- 
ever, that there can be two or three adambulacral plates, 
placed one behind the other, and each of them carrying 
only one spine; but this is an exceptional case. 
Asterias groænlandica, St., with which it has heen pro- 
posed to identify Asterzas miilleri, has the same two forms 
of pedicellariz which have heen described previously; and 
its pedicellariz differ in no respect from these. But, whilst 
the rectiform pedicellariz are only found, sparingly, along 
the ambulacral furrow in Asterzas miilleri, they are pre- 
sent in rich abundance in Asterias grænlandica, where, they
