sige Rækker paa hverandre, Tab. IX, Fig. 7, b. De ven- 
trale Randplader ere flade, næsten lancetformige i Inter- 
brachialrummene, Tab. IX, Fig. 7, ¢ men bliver mindre 
og mere ovale paa selve Armen, Tab. IX, Fig. 7,d. 8,a. 
Skelettet frembyder ikke noget særdeles forskjelligt 
fra det hos Solaster papposus; kun ere Adambulacralpla- 
derne forholdsvis større og bære paa deres Rand de tidli- 
gere beskrevne 15—17 Piege, Tab. IX, Fig. 8,0. 14,a,0. 
Mundpladerne have paa hver konvex Siderand 6—8 smaa 
Kalkpigge; paa den inderste, afrundede Rand 5—6 meget 
lange, stærke Pigge, der som ender rage ind mod Mund- 
aabningen, og paa den midterste Del 2 Rader, 4—5 1 hver, 
temmelig lange, næsten opretstaaende Kalkpigge. 
Odontophoren bestaar af 3 Stykker, en nederste, sma- 
lere Del, der er næsten firkantet, Tab. IX, Fig. 7, e, og 
en øverste, bredere, mere afrundet Del, der paa Midten er 
delt efter Længden, Tab. IX, Fig. 7, f. 
Farven er kjødrød med mørkerøde, spredte Pletter 
paa Skivens og Armenes Rygflade, medens Bugfladen er 
gulhvid.

Sammenstille vi nu denne Art med Solaster pap- 
posus, som den vel kommer nærmest, saa ville vi finde, at 
den væsentlig adskiller sig fra denne. 
Solaster affinis har konstant 10 Arme, medens S. pap- 
posus har fra 11—13. 
gere fra hverandre. 
Armene ere kortere og staa læn- 
Paxillerne ere kortere og staa længere 
Respirationsrørene ere langt færre i Antal, 
hvilket især er fremtrædende paa Armene, og ere ikke saa 
konisk tilspidsede som paa Sol. papposus. Hver Adambu- 
lacralplade bærer 15—17 Pigge, hvoraf de 7 ere de egent- 
lige Furepapiller, imedens disse hos Sol. papposus ere 4, 
sjelden 5. 
fra hverandre. 
Interbrachialrummene ere temmelig brede og 
tæt besatte med Paxiller, hos Sol. papposus ere de smale 
og næsten nøgne. Hudskelettet er finere bygget og har tæt- 
tere Masker end hos Sol. papposus; de Plader, der kunne 
betragtes som dorsale Randplader, ere rudimentære, og en- 
delig er Odontophoren 3-delt. 
each other in close irregular series Pl. IX, fig. 7,0). The 
ventro-marginal plates are flat, and in the interbrachial 
space almost lancet-formed (Pl. IX, fig. 7, c), but, upon 
the ray itself, they become smaller and more ovate (Pl. IX, 
fig: 7, d. Sa): 
The skeleton presents nothing particularly, different 
from that of Solaster papposus, except, only, that the adam- 
bulacral plates are proportionally larger, and carry on their 
margin, the previously described double set of spines, 
15—17 in each double set (Pl. IX, figs. 8, b. 14, a, 0). 
The oral plates have 6—8 small calcareous spines on 
each convex lateral margin, and, upon their inner rounded 
margin, 5-6 very long, strong spines project, like teeth, in- 
wards, and towards the oral opening. and on the mesial 
part of the oral plate, there are 2 series of pretty long, 
nearly vertical, calcareous spines, containing 4—5 spines 
in each series. 
The odontophore consists of 3 pieces, viz. an inferior, 
narrowish, and nearly square part, (Pl. IX, fig. 7, e), and 
a superior, broadish, more rounded part, which is divided 
lengthwise, in the middle, into two parts (Pl. LX, fig. 7,/f). 
The colour, is flesh colour with dark red, scattered 
patches upon the abactinal surface, whilst, upon the actinal 
surface the colour is yellowish-white.

If we, now, compare this species with Solaster pap- 
posus, which it, presumably, most resembles, we will find 
that it is still, materially, different from that species. 
Solaster affinis has invariably 10 rays, whilst Solaster 
papposus has from 1I—13 rays. The rays are also shorter, 
and placed at wider intervals from each other. The pax- 
illæ are shorter and situated more apart. The tentacular 
tubes are much fewer in number, and this is prominently 
the case upon the rays; and, neither, are they so acumin- 
ated as in /Solaster papposus. Each adambulacral plate 
carries 15—17 spines, of which, 7 spines are the genuine 
furrow papillae, whilst, in Solaster papposus, there are only 
4 spines, and, very rarely, 5. The interbrachial spaces are 
pretty broad, and closely beset with paxillæ, whilst, in Sol- 
aster papposus they are narrow, and nearly bare, The 
dermal skeleton is more slender in construction, and has 
closer meshes than in Solaster papposus, and the plates, 
which may be considered to be dorso-marginal plates, are 
rudimentary, and finally, the odontophore is trichotomous.
