_ af de: sædvanlige Lag og adskiller sig ikke 1 saa Henseende 
fra den foregaaende Arts Hud. 
I Corium ere forskjelligformede Kalklegemer leirede. 
I det ydre Lag findes de under Jeffreys: beskrevne stjerne- 
dannede Grupper, der bestaa i, Regelen af 5 spatelformede 
Kalkstave, fra hvis Midte Ankeret rager frem, Fig. 34. 
Kun ere disse Grupper i langt større Mængde tilstede, og 
ere stillede i næsten regelmæssige Rækker hos denne Art. 
Kalkspatlernes Skaft er noget kortere, Bladet noget min-- 
dre, men mere afrundet og forsynet med flere Huller, Fig. 
34, a: Ankerstokken er noget kortere og tykkere, og paa 
Kløernes ydre Rand er der 4 Takker, Fig. 34, b. Disse 
stjerneformige Kalklegemer ere indesluttede i særegne Pa- 
piller, der dannes af Bindevævet og ere beklædte med Epi- 
thelet og Cuticula; kun Ankeret rager med sin yderste 
Ende udenfor Papillen. 
Ved Siden af disse Legemer, dels i Niveau med dem, 
dels noget dybere i Bindeveyet, sees, foruden de alminde- 
lige gjennembrudte Kalkplader med Krone, hvilke dog hos 
denne Art er i saa hoi Grad uregelmæssige med Hensyn 
til Formen, at det er vanskeligt at finde 2—3, der fuld- 
kommen ligne hverandre, endnu andre Kalklegemer, der — 
ere ganske særegne. De bestaa af et Midtparti, hvorfra 
udgaa som oftest 3, stundom 4 Stammer; disse dele sig 
atter i 2 Grene, som lobe snart lige ud, snart krumme de 
sig noget, og kun sjeldent forene de sig, Fig. 31, 32, 33. 
Fra Centrum Slags Krone, 
pig ender som en spids Naal; men som ogsaa ofte har en 
bredere Ende, forsynet med 3 afrundede Knuder, Fig. 31, 
a', Begge disse Slags Kroner, der gaa igjennem Papiller- 
nes Aabning, ere beklædte med en Bindevævsskede, som 
hæver sig: en der hyp- 
naar op imod Enden, og udenpaa hvilken er Bpithel- og 
Cuticulalaget.  Imellem disse Kalklegemer ligge paa enkelte 
Steder af Ryggen et og andet yderst lidet, næsten rundt 
Kalkkorn, der har en mørk-vinrød Farve; men under det, 
eller rettere indenfor, altsaa i et dybere Lag af Corium, 
iagttages en stor Mængde farvefrie Kalklegemer, der ere 
mere eller mindre afrundede og bestaa af et Conglomerat 
af Kalkkorn eller Kalkprismer, Fig. 35, 36. 
findes desforuden temmelig meget grønligt Pigment, der 
ligger i uregelmæssige Klumper. 
Fordoielsesorganerne frembyde intet Særegent. Kun 
det venstre Tarmappendix er noget lengere, end paa Jef- 
freysii, og er næsten lige fra dets Udspring besat med 
Smaablærer, Fig. 30, 0. 
AB ‘Det indre Skelet, Kalkringen, er ligesom hos Jeffrey- 
sii fuldstændig forkalket, saa at det ikke er muligt at skille 
‘de enkelte Stykker fra hverandre; imidlertid kunne Som- 
mene temmelig tydeligt iagttages under Loupen. Det er 
muligt, at Kammene,: saavel paa Radial- som Interradial- 
stykkerne, ere mere fremspringende, og Spidserne paa den

the papillæ, 
perceptible, — the viscera however less so. The integ- 
ument is composed of the usual layers, and im this respect 
does not differ from the skin in the foregoing species. 
In the corium are embedded calcareous corpuscles, 
varying in form. In the outer layer occur the stellate 
groups observed in Jeffreysii, consisting as a rule of 5 spatu- 
late calcareous rods, from the middle of which protends 
the anchor, fig. 34. These groups are, however, far, more 
numerous in the present species, and are arranged in almost 
regular series. The shaft of the calcareous spatulæ is some- 
what shorter; the lobule somewhat smaller, but more rounded 
and furnished with a greater number of apertures, fig. 33, a. 
The stock of the anchor is a trifle shorter and thicker, 
and on the outer margin of the ‘arms are seen 4 spines, 
fig. 34, b. These stellate caleareous corpuscles lie enclosed 
in special papilla, consisting of connective tissue, and are 
covered by the epithelium and-the cuticle; the anchor only 
projects with its outer extremity above the papilla. 
Approximating these corpuscles, either in the same 
plane or embedded somewhat deeper in the connective 
tissue, are seen, exclusive of the more numerous per- 
forate calcareous plates with corolle, — which however in 
this species vary so much with regard to form that: it is 
difficult to find two or three exactly alike, — other cal- . 
careous corpuscles, essentially distinct. They consist of a 
central portion, from which proceed generally 3, some: 
times 4 stems, that divide dichotomously, the 2 branches, 
sometimes straight, sometimes slightly bent, seldom unit- 
ing, figs. 31; 32; 33. From the centre springs a kind 
of corolla, which frequently terminates in a sharp spicule, 
but which, too, has often a broader extremity, fur- 
nished with 3 rounded protuberances, fig. 31, a. Both- 
kinds of corolle, which pass the opening of 
have a sheath of connective tissue, that 
reaches up towards the extremity, and is covered by the 
epithelial and cuticular layers. Between these calcareous 
corpuscles occur on certain parts of the back one or two 
extremely small, almost round calcareous granules,. of a dark 
through 
vinous red: but underneath the granules, or rather lower 
down, in a deeper layer of the corium, are seen large 
numbers of colourless calcareous. corpuscles, more or less 
rounded, and consisting of an agglomeration of calcareous 
granules, or calcareous prisms, figs. 35; 36. In the connec- . 
tive tissue also occurs a considerable quantity of a 
greenish pigmentary substance, distributed im irregular 
lumps. 
The digestive organs exhibit no peculiar feature. The 
left intestinal appendix, however, is somewhat longer than 
in Jeffreysii, and is beset, almost from its origin, with small 
vesicles, fig. 30, b. 
The calcareous skeleton — the calcareous ring — is, 
as in Ankyr. Jeffreysii, completely calcined, and hence it 
is quite impossible to separate one from the other the 
segments composing it; the sutures, however, when viewed 
under a lens, appear comparatively distinct. Possibly, the 
combs both on the radial and the interradial segments project
