Hudskelettet dannes paa hele Rygfladen af storre og 
mindre, taglagte Kalkstykker, der have en noget forskjellig 
Form. Paa Skiven ere de størst, have i Almindelighed 
flere korte Forlængelser, der ved at lægge sig over paa de 
tilstødende Kalkstykkers Udløbere. bidrage til at danne et 
Kalknet med yderst smaa Masker, hvori findes en Ambu- 
lacralpore, Tab. IX, Fig. 5,0. Paa Armenes Ryg har 
Kalknettet lidt videre Masker, men paa Siderne bliver det 
kompaktere, Maskerne’ mindre og regelmæssigere, og de 
enkelte Kalkstykker have her Formen af et X med sær- 
deles bredt Midtparti, Tab. IX, Fig. 5, c. 
Paa Bugfladen bestaar Hudskelettet af Kalkplader 
med 3 eller 4 Udløbere, som ere taglagte og indtage hele 
Interbrachialrummet, Tab. IX, Fig. 5, d. 
De ventrale Randplader ere meget smaa, smale, lang- 
strakte Kalkstykker, som paa deres ydre Flade bære den 
Kam af Paxiller, der ligesom danner Søstjernens Rand, 
Tab. IX, Fig. 5,e. 6, a De dorsale Randplader ere 
end mindre, men have samme Form som de ventrale og 
bære en Paxille, Tab. IX, Fig. 6, 0.

The dermal skeleton of the whole of the dorsal surface, is 
formed of larger and smaller imbricate calcareous ossicles, 
whose form is somewhat varied. They are largest on the disk, 
and, usually, have several short projections which laminate with 
the projections of the adjoining calcareous ossicles, and thus, 
assist in forming a calcareous reticulation having extremely 
small meshes, in each of which, an ambulacral pore is visible 
(Pl. IX, Fig. 5,0). On the abactinal surface of the rays, the 
calcareous reticulation has slightly wider meshes, but, on the 
lateral surfaces, the reticulation becomes more compact, 
and the meshes are smaller and more regular, whilst, the 
individual calcareous ossicles have, here, the form af an X, 
with a particularly broad crucial part (Pl. IX, fig. 5, ¢). 
The dermal skeleton of the actinal surface consists of 
calcareous plates having 3 or 4 projections, which are im- 
bricate, and include the entire interbrachial space (Pl. IX, 
fig. 5, d). 
The ventro-marginal plates are very small, narrow, 
elongate, calcareous ossicles, and they carry on their ex- 
terior surface, the ridge of paxille, which, as it were, 
forms the margin of the starfish (Pl. IX, fig. 5, e. 6, a). 
The dorso-marginal plates are still smaller, but have the 
same form as the ventro-marginal plates, and carry one 
paxilla (Pl. IX, fig. 6, 0). 
In the middle of its superior margin, the odontophore 
has a rather prominent protuberance. The dorsal apo- 
physis is small (Pl. IX, fig. 5, f). 
The adambulacral plates are rather large, and are 
pentagonal or hexagonal im shape, with concavo-convex 
surfaces, and they are furnished with spines which have 
previously been referred to (Pl. IX, fig. 6, c). The am- 
bulacral plates do not materially differ from the form per- 
taining to the genus Solaster.
