Odontophoren, dér er temmelig stor med vingeformede
Sideudbredninger, har et Indsnit saavel paa Oral- som
Yentralsiden med en liden Dorsalapophyse, Fig. 7, /.
Skelettet. Ambulacralpladernes Tverprocesser ende
med et bredt Indsnit, der ganske omfatter de temmelig
smaa, afrundede Adambulacralpladers øvre, næsten lige
Rand, hvorved disse saagodtsom ganske skjules.
Ambula-cralaabningerne danne to regelmæssige Linier, ligefra
Skiven til Armens Ende. Adambulaoralpladerne bære dels
en, dels to Papiller, hvoraf den inderste altid er den
længste.
Ocularpladen er liden, stærkt buet]; dens yderste Rand
er forsynet med smaa Kalkpapiller.

careous piates, already spoken of, and which may be
considered to be ventro-marginal plates. — These,
occasionally, unite with the dorso-marginal plates by means of a
small narrow calcareous ossicle; sometimes, there is no
such ossicle between them, in which case, they become
directly united to each other.
The odontophore is rather large, with wing-formed
lateral extensions, and has a groove on both the oral and
ventral surfaces, with a small dorsal apophysis (fig. 7,/).
The skeleton. The transverse processes of the
ambulacral plates terminate in a broad groove, which, includes
completely, the rather small, superior, rounded, almost
straight margin of the adambulacral plates, causing them
to be nearly quite concealed. The ambulacral openings
form two regular lines, extending, right from the disk to
the extremity of the rays. The adambulacral plates carry,
sometimes, one, sometimes, two papillæ, of which, the
inner one is always the longest.
The ocular plate, is small; sharply arched; its exterior
margin is furnished with small calcareous papillæ.
The colour. — The abactinal surface is a beautiful
vermillion, with white pedicellariæ around the spines. The
actinal surface is white.

Dr. Stuxberg har i sin Meddelelse over Echinodermer
fra Novaja Semlja i korte Drag beskrevet ovennævnte
Søstjerne, hvoraf der paa Nordhavsexpeditionen blev fundet
endel Exemplarer, der efter Stuxbergs Maal at dømme ere
betydelig større, end de af ham fundne.
Legemet er femarmet, og dets Diameter fra den ene
Armspids til den anden 470mm. Den lille Radius forholder
sig til den store som 1 : 11 Vi-
Armene ere stærkt hvælvede paa Rygfladen, næsten
flade paa Bugsiden. De ere smale ved deres Udspring,
omtrent 80mm i Omkreds, imedens de opnaa den største
Tykkelse, 112""" i Omkreds, henimod 25""" fra Skivens

In his report upon Echinodermata from NovaZembla.
Dr. Stuxberg gives a short description of this starfish, a
number of specimens of which, were discovered during the
North-Atlantic Expedition, which, compared with the
measurements given by Stuxberg, are considerably larger than
these found by him.
The body is 5-rayed; and the diameter, when
measured from one brachial extremity to the opposite brachial
extremity, is 470mm. The disk radius bears to the
brachial radius, the proportion of, as 1 :11V2.
The rays are sharply rounded on the abactinal
surface, and almost flat on the actinal surface. They are
narrow at the origin, and in this situation, measure about
80mm in circumference, whilst their greatest thickness is
