Pedicellarier.  Madreporpladen næsten rund, ikke synderlig

Armenes Ryg have paa Midten en uregelmæssig Længde- 
række Pigge, der ere noget større, end de paa Skiven; paa 
Siderne sees spredte, uregelmæssig stillede mindre Pigge, 
der paa enkelte Stykker stille sig i Række. Paa tørrede 
Exemplarer er det næsten umuligt at finde nogen Regel- 
mæssighed 1 disse Pigges Stillmg. Armenes Rygflade be-

Hele Rygfladen er bedækket af tætstaaende, ligefor- 
mede, yderst kortstilkede Pedicellarier, hvorimellem sees 
lange Tentakelror; men paa 2 Exemplarer saaes paa en 
Arm endel korsformede Pedicellarier ved Grunden af en- 
kelte Pigge af den midterste Pigrække, imedens der paa 
de øvrige, ligesom paa et amerikansk Exemplar, kun findes 
ligeformede, saaledes som af Perrier er angivet. Han har 
nemlig paa de 5 1 Spiritus opbevarede Exemplarer i Pari- 
sermuseet ikke fundet korsformige Pedicellarier paa Ryg- 
gen, uagtet han har været meget opmærksom herpaa; han 
udtrykker sig saaledes: ,Il est å rémarquer que les épines 
du dos ne sont pas entourées de ce cercle de pédicellaires 
croisés que nous avons rencontrées jusqu'iei [d'une maniere 
constante.* Regelen synes altsaa at være, at der ingen 
korsformede Pedicellarier findes paa Rygfladen af Asterias 
stellionura.

Disse lange Pigge (ventrale

The abactinal surface of the rays has a mesial longi-

rays is bordered, by a series of short strong spines, (fig. 1). 
The entire abactinal surface is covered, with close-set, 
rectiform pedicellaria, with extremely short peduncules, 
between which, long tentacular tubes appear; but; upon two 
specimens, however, there was remarked upon one of the 
rays, a few cruciform pedicellariz, situated at the base of 
individual spies belonging to the mesial spinous series, 
whilst upon the others, just, as is also the case in an 
American specimen, rectiform pedicellarize only were ob- 
servable; as has been noticed by Perrier. He has not 
discovered cruciform pedicellariæ on the abactinal surface 
of the 5 specimens preserved in spirit in the Paris Muse- 
um, although he has directed: much attention to this. He 
»expresses himself thus: ,J] est a rémarquer que les 
sépines du dos ne sont pas entourées de ce cercle de péd- 
~icellaires croisés, que nous avons rencontrées jusquw ici d'une 
»~maniere constante.“ — The rule seems therefore to be, 
that no cruciform pedicellariz are found on the abactinal 
surface of Asterias stellionwra. 
The spinous series above described, which border the 
abactinal surface, and really form the dorso-marginal spines, 
are on the other hand, environed by a wreath, of closely 
disposed, cruciform pedicellariz (fig. 1, 2). 
The actinal surface is flat; the furrow rather narrow, 
and furnished with 2 series of ambulacral papille, of which 
the inner one, next the furrow, has the longest and grea- 
test number of spines, whilst, the spines of the outer ser- 
not so neither are they

ies are smaller and numerous,

quently, every second adambulacral plate carries only 1 
spine, whilst, the other alternate one carries 2 spines. 
In proximity to the margin of the rays, there is a 
series, of long, strong, coniform spines, regularly disposed at 
such interval from each other, that sometimes 3—4, some- 
times 5, furrow-papillæ, correspond to the interspace of 2 
spines. The long spines are 37 in number, (ventro-marg- 
inal spines) and are environed on their external margin, 
by a cluster of cruciform pedicellariz (fig. 2, a).
