Artskarakter. 



Zoanthodemet iridtil 50""" hoit. Stammen næsten lige 

 tyk overalt, kort, nøgen. Fra dens Top reiser sig 4 — 5 

 tykke, opretstaaende Grene med lidt udvidede Ender og 

 rigt besatte med Polyper. Fra Stammens overste Del ud- 

 gaa Polyper, dels enkelte, dels i sniaa Grupper. Basal- 

 delen fast, membranøst udspændt over de Gjenstande. 

 hvortil den er fæstet. Polyperne indtil 8""" lange, cylin- 

 driske, med en udpræget Bagkrop, forsynet med 8 adskilte 

 Længderibber. Forkroppen har op imod Mundskiven 8 

 triangulære Rum. i hvis Midte en Spikelrække. Tentak- 

 lerne omtrent halvt saa lange som Kroppen med temmelig 

 lange Pinnuler. Svælget har 3 enkle Spikelrækker paa 

 hver Side med et lidt nogent Mellemrum paa Ryg- og 

 Bugside. Polypcellerne ere runde, ikke over Coenenchy- 

 mets Niveau, med takket Rand. naar Polypen ikke er ud- 

 strakt. Paa. Basaldelen ere sammensatte Stjerner. Dobbelt- 

 stjerner og Klubber almindeligst ; paa Stammen og Grenene; 

 ere bladede Spindler, Dobbeltstjerner og Klubber hyppigst 

 paa Polypens Bagkrop er sammensatte Stjerner, og paa 

 Forkroppen er Tentakler. Pinnuler og takkede Spindler 

 mest fremtrædende. Farven hvid. spillende lidt i det Gule

Zoanthodemet buskformet, omkring 30""" hoit. Basal- 

 delen skiveformigt udvidet, fast og stærkt inkrusteret af 

 Kalk. Stammen omtrent 25'""' i Omkreds ved Grunden. 

 smalner lidt af op imod den afrundede Top, der er tæt

Speciflc characteristics. 



The Zoanthodem measures up to 50""" in bright. 

 The stem, almost uniform in thickness throughout, short. 

 and bare; from its summit 4 — 5 thick erect branches 

 issue. having slightly dilated extremities, and richly beset 

 with polyps. From the uppermost part of the stem. pol- 

 yps issue, placed. partly, solitarily, partly, in small groups. 

 The basal part hard. and membranaceously extended over 

 the objects to which it is attached. The polyps measure 

 up to 8'"'" in length, are cylindrical, have a prominent 

 posterior body furnished with 8 separated longitudinal ribs. 

 Towards the oral disk, the anterior body has 8 triangular 

 spaces having a spicular series in their middle. The ten- 

 tacles measure about half the length of the body and 

 have pretty long pinnules. The gullet has 3 single series 

 of spicules on eacli side. with a small bare interval on 

 the dorsal and ventral side. The polyp-cells are cylindri- 

 cal and do not project above the surface of the sarcosoma 

 and they have a spicate margin when the polyp is retrac- 

 ted. On the basal part complex stellates. bi-stellates and 

 clavates, are the most frequent forms; on the stem. and 

 on the branches. foliaceous fusees, bi-stellates and clavates 

 are the most frequent forms. On the posterior body of the 

 polyp. complex stellates ; and on the anterior body, ten- 

 tacles. and pinnules, spicate fusees are the most predomin- 

 ant spicular forms. Colour. white, shading a little towards 

 yellow.

The Zoanthodem is fruticose, and measures about 

 30'"'" in height. The basal part is discoidally dilated, and 

 is hard and strongly encrusted with calcium. The stem 

 measures about 25""" in circumference at the base. and
