noget udvidede i deres fri Ende, som er forsynet med 3— 
5 Spidse og ere ikke i Almindelighed koniske, som af Sars 
angivet. 
Pedicellarierne, der findes overalt paa Rygfladen, ere 
korsformede. Sars’s Beskrivelse og Afbildninger af disse 
Gribeorganer ere ikke ganske korrekte, hvilket sandsynlig- 
vis hidrører, dels fra, at han ikke tilstrækkelig har berøvet 
dem deres Hudovertræk, og dels derfra, at enkelte af de 
Pedicellarier, som findes paa Skiven og Midten af Armene, 
ere noget mindre, og deres Kjævers forlængede Del ender 
afrundet. Størstedelen af Pedicellarierne, især de langs 
Armenes Sider, som findes paa det Originalexemplar, vi 
have havt til Undersøgelse, ligesom paa de øvrige Exem- 
plarer, der have staaet til vor Raadighed, ere fuldsændig 
formede som de af Dr. Sladen beskrevne og afbildede, til- 
hørende hans nye Art, &Pedicellaster palæocrystallus, og 
hvortil vi kunne henvise. 
Furepapillerne, der staa i to Rækker, ere formede paa 
samme Maade som Rygpiggene, men have, foruden paa 
deres fri Ende, ogsaa paa Siderne Takker. Paa de Ex- 
emplarer, der ere fundne i de arktiske Regioner, ere Tak- 
kerne stærkere udviklede, end Tilfældet er paa dem, som 
ere fundne ved de norske Kyster. 
Vi skulle nu meddele Maalene af de Exemplarer, vi 
have disponeret over, samt Findestederne.

these have not been remarked by cither Sars or Sladen. 
The dorsal spines consist of perforated plates, and are some- 
what expanded at their free extremity, they fur- 
nished with 3—5 points, and are not usually coniform, as 
Sars states. 
The pedicellariæ, which are, everywhere, found upon 
Sars’ description and 
are 
the abactinal surface, are cruciform. 
illustration of these forcipate organs is not quite correct, 
arising, presumably, from, partly, his not having sufficiently 
removed from them, their membranous covering, and, partly, 
from the fact, that some of the pedicellariz found on the 
disk and mesial portion of the rays, are somewhat smaller 
than the rest, and have the elongate portion of the jaws 
rounded off at the extremity. Most of the pedicellariæ, 
especially those found on the lateral surfaces of the rays 
of Sars’ original specimen, as well as, upon the rays of the 
other specimens at our disposal, and which we have had 
under examination, are formed, exactly, like those described 
and illustrated by Dr. Sladen, as pertaining to his new 
species Pedicellaster palæocrystallus, and to which we may 
refer. 
The furrow-papillæ are placed in two series, and, are 
formed in the same manner as the dorsal spines, but, in 
addition, are furnished on their free extremities, and lateral 
surfaces, with aculeæ. In the specimens found in the Arc- 
tic region, the aculez are more developed than is the 
case in those found on the Norwegian coast. 
We shall now state the dimensions of the specimens 
we have had at our disposal, and the localities where they 
were found. 
Husøen (Sognefjord). 
rays uniform in length. The 
No. 1. 10” in diameter, 
proportion of the disk-radius to the brachial 
radius is, as 1:3. The furrow-papillæ aculeated. 
No. 2. 11”” in diameter. 3 extremely short rays 
and 2 long ones. The proportion of the disk 
radius to the brachial radius is, as 1:37/;. The 
furrow-papillæ aculeated. 
Moldøen. 11”” in diameter, dried specimen. The pro- 
portion of the disk-radius to the brachial rad- 
lus is, as 1:2'/5. The rays uniform in length. 
The furrow-papillæ aculeated. 
Bodø. 30”” in diameter. 2 short and 3 long rays. 
The proportion of the disk-radius to the bra- 
chial radius is as 1:4*/;. The furrow-papillæ 
aculeated. 
Station No. 164. 16”” im diameter. The proportion 
of the disk-radius to the brachial rad- 
ius is as 1:5'/3. The furrow papillæ, 
lateral surfaces, and dorsal spines, much 
aculeated. One short ray, 4 rays nearly 
uniform in length. 
Station No. 173. 16”" in diameter. The proportion of 
the brachial radius 
a little shorter
