Artskarakter. 



Zoanthodemet busket, incltil 25™'" høit. Stammen 

 rund, furet, haard. grenet. Basaldelen membranagtig, 

 skiveformet udvidet. Grenene indtage hele Stammen lige 

 fra G-runden til Toppen, ere korte, tykke, udelte og bære 

 paa deres Ende flere Polyper, som dels staa enkeltvis, dels 

 i Grupper. Polyperne ere cylindriske, retraktile ; paa For- 

 kroppen 8 Længderibber, dannede af lange, smale, næsten 

 glatte, spindelformede Spikier, der gaa over paa Tentak- 

 lerne ; saavel disse som Pinnulerne spikelholdige. Bag- 

 kroppen kortere ; Spiklerne ligge her paatvers, og Spindel- 

 og Klubformen er mest fremtrædende. Basalens Spikier 

 ere væsentlig sammensatte Stjerner med bladformede Straaler, 

 samt bladede Spindler. Stammen og Grenene ere ligeledes 

 rige paa Spikier, og her tindes almindeligst takkede Klubber, 

 sammensatte Stjerner, bladede Valser og Spindler. 1 

 Stammens og Grenenes Coenenchym (paa Skillevæggene) 

 Spikelafsætninger, bestaaende af sammensatte Stjerner med 

 bredbladede Straaler med tungede Rande, bladede Spindler 

 og Køller. Septa spikelholdige og paa Svælget 4 Rækker 

 Spikier. Farven hvidgul med et svagt brunligt Skjær.

 den fæster sig. Fig. 1. Stammen er fast, furet paalangs, 

 læderagtig og henved 30'"'" i Omfang ved Grunden. men

 sig lidt op til Toppen, der er næsten kolbeformig og tæt 

 besat med Polyper, Fig. 2. Den nederste Del af Stammen 

 er nøgen ; men omtrent 8'"'" fra Basaldelen sees paa den ene 

 Side en Række af 5 — 6 enkeltstaaende Polyper, Fig. -1;

Habitat. 



Station No. 192. Two specimens, of which one is 

 only slightly developed. 



Specific characteristics. 



The Zoanthodem fruticose, measures up to 25'"'" in 

 height. The stem cjdindrical, furrowed, hard, ramous. 

 The basal part, membranaceous, discoidally dilated. The 

 branches occupy the entire stem, right from the base to 

 the summit; they are short, thick, non-ramous, and carry 

 on their extremity several polyps, which are situated, 

 partly singly, partly in groups. The polyps are cylindrical, 

 retractile. In the anterior bod), 8 longitudinal ribs, 

 formed of long, narrow, almost smooth fusiform spicules, 

 which pass over into the tentacles; these as well as the 

 pinnules contain spicules. The posterior body shorter ; the 

 spicules, here, placed transversally, and the fusiform and 

 claviform most predominant. The spicules of the basal 

 part are, principally, complex stellates with foliated rays, 

 also foliated fusees. The stem and the branches are, like- 

 wise, rich in spicules and, here, the forms most frequently 

 found are, spicate clavates, complex stellates, foliatBd 

 rollers and fusees. In the divisional walls of the sarcosoma 

 of the stem and the branches, spicular deposits, consisting 

 of complex stellates, with broad foliate rays having linguate 

 margins, also foliate fusees and subclavates. Septa spicular, 

 .and in the gullet 4 series of spicules. Colour whity-yellow. 

 with a faint brownish tinge.

PI. XVII., figs. 1—54. 



The Zoanthodem measures up to 25'"'" in height. 

 The basal part is membranaceously dilated, and encloses 

 the objects to which it attaches itself (fig. 1). The stem is 

 hard, longitudinally grooved, and coriaceous, and it measures 

 about 30""" in circumference at the base, but diminishes, grad- 

 ually, up towards the middle, from whence it again dilates a 

 little up towards the summit, which is almost claviform and 

 closely beset with polyps (fig. 2). The lowest part of the 

 stem is bare, but about 8""" from the basal part, upon one 

 of- the sides, there is seen a series of 5 — 6 polyps, placed 

 separately (fig. 1). A little further up the stem, the bran- 

 ches begin to occur, and these are placed irregularly, and 

 far apart from each other. They are very thick and 

 short, and have almost globular extremities which are
