Paa Bagkroppen iagttages lignende Spilder som paa 

 Forkroppen, kun ere Spindlerne her meget hyppigere, mere 

 takkede og tildels meget mindre, Fig. 38. 39. Desfornden 

 træffes her en næsten glat, liden Firling, noget lig et 

 Andreaskors med 0.060'""" lange Arme, Fig. 40. 



Paa Tentaklerne er det væsentligst bladede, dels 

 krumme, dels lige Køller, som ere ordnede saaledes. at 

 den tykke, bladede Del af Kollen vender mod Midten af 

 Tentakelens aborale Side; de ere fra 0.140 — 0.200""" lange 

 og 0.036""" brede foroven, Fig. 41; opimod den øverste 

 Ende af Tentakelen sees en Del næsten flade, i Eanden ud- 

 skaarne Spikier, som ere fra 0.060—0.080""" lange og fra 

 0.014— 0.024""" brede, Fig. 42; endelig iagttages enkelte 

 smaa Rosetter, der ere omtrent lige lange som brede og 

 noget indknebne paa Midten, nærmende sig en liden 

 Dobbeltstjerne og 0.020""" i Udstrækning, Fig. 43, samt 

 smaa, bladede Klubber, Fig. 44. 



Farven. 



Bleg rosenrød. 



Findested. 



Station 315. Et Exemplar. 



Slægtskarakter. 



Zoanthodemet trædannet, forgrenet. Hovedgrenene 

 tykke, og fra dem udspringe overalt Smaagrene, tæt besatte 

 med Polyper. Polyperne ikke retraktile, langstrakte, med 

 vel udviklet Bagkrop. Stammen, Grenene, Smaagrenene og 

 Polyperne rige paa Kalkspikler, hvoraf Kølleformen er 

 den mest fremherskende. Septa uden Kalk. 



Artskarakter. 



Zoanthodemet indtil 80""" høit. Stammen furet paa- 

 langs, forgrenet, 40""" i Omkreds ved Grunden. Basaldelen 

 fast, læderagtig, ikke udvidet. Stammen jævntyk overalt, 

 udvider sig lidt i Toppen, hvor den bærer 3 Grupper 

 Polyper. Hovedgrenene overalt rige paa Smaagrene, tæt 

 besatte med Polyper. Stammen og samtlige Grene rige 

 paa Kalkspikler. Polyperne indtil S mm lange, ikke retraktile, 

 med en lang Bagkrop og ligesom indkapslede i kølleformede 

 Spikier. Tentaklerne meget rige paa lignende Spikier. 

 Farven bleg rosenrød. 



On the posterior body, similar spicules to those of 

 the anterior body are observed, only, in this situation, the 

 fusees are much more frequent, more spicate, and partly, 

 also, much smaller (figs. 38. 39). There is, further, met 

 with, here, an almost smooth, small, quadruplet, somewhat 

 like a S* Andrews Cross, with arms measuring 0.060""" 

 in length. 



On the tentacles, it is, principally, foliaceous, partly 

 bent, partly straight, subclavates that are met with, arranged 

 in such manner, that the thick foliaceous part of the club 

 faces towards the middle of the aboral side of the ten- 

 tacle; these measure from 0.140—0.200'"'" in length, and 

 0.036™"' in breadth above (fig. 41). Up towards the 

 uppermost extremity of the tentacle, a number of, almost 

 flat, spicules with indented margins are seen, measuring 

 from 0.060—0.080»"" in length, and from 0.014—0.024'""' 

 in breadth (fig. 42); finally, a few small rosettes are ob- 

 served, which are about as long as they are broad, and 

 somewhat constricted at the middle, and measuring 0.020 mm 

 in extent (fig. 43); also, small foliaceous clavates (fig. 44). 



Colour. 



Pale rose-red. 



Habitat. 



Station No. 315. One specimen. 



Generic characteristics. 



The Zoanthodem arborescent, ramous. The main 

 branches thick, and from them shoot out, everywhere, 

 branchlets closely beset with polyps. The polyps non- 

 retractile, elongate, with well developed posterior body. 

 The stem, the branches, the branchlets and the polyps 

 rich in calcareous spicules, of which, the subclavi-form is 

 the most predominant. Septa non-calcareous. 



Specific characteristics. 



The Zoanthodem measures up to 80""" in height. 

 The stem longitudinally grooved, ramous, and 40""" in cir- 

 cumference at the base. The basal part firm, coriaceous, 

 and not dilated. The stem uniform in thickness through- 

 out, but dilates a little at the summit, where it carries 3 

 groups of polyps. The main branches, everywhere, rich in 

 branchlets closely beset with polyps. The stem, and all 

 of the branches, rich in calcareous spicules. The polyps 

 measure up to 8""" in length, are non-retractile, have a 

 long posterior body and are, as it Avere, encapsuled in 

 subclavi-formed spicules. The tentacles richly furnished 

 with similar spicules. The colour pale rose-red.
