Legemet 5-straalet. Ryggen temmelig hvelvet. Bugen 
flad. Armene lengere og smalere, end paa Hovedformen. 
Den lille Radius forholder sig til den store som 1:2. 
Paa Rygfladen sees foruden Paxillebeklædningen mange 
enkeltstaaende, runde Knuder, som staa tættere paa Ar- 
mene, end paa Skiven, Tab. X, Fig. 5. 6. 
Madreporpladen næsten rund; sidder omtrent midt 
imellem Armvinkelen og den subcentrale Anus, dog noget 
nærmere den første, Tab. XV, Fig. 3. 
Ambulacralfuren har 3 Rækker Pigge, hvoraf en ven-

Randen er temmelig udpræget og dannes især af de 
ventrale Randplader, der ere meget tydelige; de dorsale 
Randplader ere mindre iøinefaldende, men kunne dog sees. 
I Ryggens Hudskelet ere de Kalkplader, der svare til 
Knuderne paa Overfladen, meget fortykkede, større i Om- 
fang og runde (sammenlignet med Hovedformen).

The abactinal surface is arched, 
and the actinal surface is flat. The rays are longer and 
narrower than those of the normal form. The disk radius 
bears to the brachial radius, the proportion of, as, 1: 2. 
Besides the paxillar covering, there is seen, on the 
abactinal surface, numerous solitary circular knobs, which, 
upon the rays, are placed closer together than on the disk

The madreporite is nearly circular, and is situated, 
about midway between the brachial angle and the submes- 
lal anus, but rather nearer to the first named (Pl. XV, 
fig. 3). 
The ambulacral furrow has 3 series of spines, of 
which, the one series turns in towards the furrow, and 
each series consists, of only a single spine (Tab. X, fig. 7). 
The margin is well defined, and is especially formed 
by the ventro-marginal plates; which appear very promin- 
ently. The dorso-marginal plates do not appear so prom- 
inently, but yet, are visible. 
In the abactinal dermal skeleton, the calcareous plates 
which correspond with the knobs on the surface, become 
much thicker, more circular in form, and larger in cir- 
cumference, than those of the normal form. 
The body fis 5-rayed.
