 87; de andre Former ere mere eller mindre takkede, dels 

 med stumpe, dels tilspidsede Ender og fra 0.128—0.204""" 

 lange og 0.036""" brede, Fig. 88. 89. 



Paa Svælget ere Spiklerne noget fladtrykte og have 

 en meget forskjellig Form, snart som Spindler, snart nærme 

 de sig Dobbeltstjernen, snart Spatelen, snart Firlingen. 

 De ere i Regelen takkede med indskaarne Rande og stun- 

 dom spaltede Ender; de ere fra 0.072—0.128""", Fig. 90.

Artsk ar akter. 



Zoanthodemet buskformet, omtrent 30""" høit. Basal- 

 delen skiveformet udvidet, haard af inkrusteret Kalk. 

 Stammen af omtrent 25""" Omkreds ved Grunden, smalner 

 lidt af mod den afrundede Top, der er tæt besat med 

 Polyper. Grenene ere faa, men brede, udspringe et Stykke 

 ovenfor Basaldelen og slutte sig tæt til Stammen; de 

 nederste Grene ere længst og bredest, men alle ere, især 

 paa deres noget afrundede Ende, tæt besatte med Polyper. 

 Stammen og Grenene haarde, læcleragtige, rige paa Kalk. 

 Polypcellerne korte, cylindriske, stillede mere eller mindre 

 fra hverandre, stærk kalkholdige. Polyperne indtil 12™'" 

 lange, cylindriske, lidt indknebne mellem For- og Bagkrop, 

 meget spikelrige; Forkroppen forsynet med 8 Længderibber. 

 Tentaklerne omtrent 4" m lange ; den aborale Side indkapslet 

 af Spikier. Pinnulerne vel forsynede med Spilder. Svælget 

 har 8 enkle Rækker Spikier. Paa Basaldelen ere Dobbelt- 

 stjerner og Klubber, paa Stammen sammensatte Stjerner og 

 paa Grenene Klubber hyppigst. Paa Polypens Bagkrop ere 

 Klubber og sammensatte Stjerner mest fremtrædende, og 

 paa Forkroppen ere store Spindler almindeligst. Farven gul. 



0.028""" in breadth (tig. 86). The spatula-shaped spicules 

 extend farthest into the pinnules, and have spicate mar- 

 gins; they measure 0.168™" in length, and 0.044'"'" in breadth 

 in the leaf (fig. 87); the other forms are more or less 

 spicate, partly, with blunt, partly, with acuminate extre- 

 mities; they measure from 0.128 — 0.204'"'" in length, and 

 0.036'"'" in breadth (figs. 88. 89). 



On the gullet, the spicules are somewhat flattened 

 and have a very variable form, appearing sometimes as 

 fusees, sometimes approaching in form to the bistellate, 

 sometimes, to the spatula-form, and, again, sometimes to 

 the quadruplet-form. They are, as a rule, spicate, and 

 have dentated margins, and occasionally appear with fis- 

 sured extremities; they measure from 0.072 — 0.128'"™ in 

 length (fig. 90).

Specific characteristics. 



The Zoanthodem fruticose; measures about 30""" in 

 height. The basal part discoidally dilated, hard, owing to 

 encrusted calcium. The stem measures about 25""" in 

 circumference at the base, diminishes in thickness a little, 

 upwards, towards the rounded summit, which is closely 

 beset with polyps. The branches are few in number, but 

 broad; issue a little distance above the basal part, and close 

 tightly in to it. The lowest branches are the longest, and 

 broadest, but all of them are — especially on their somewhat 

 rounded extremities — closely beset with polyps. The 

 stem, and the branches, hard, coriaceous, rich in calcium. 

 The polyp-cells short, cylindrical, placed more or less 

 apart from each other and strongly calcareous. The polyps 

 measure up to 12'"™ in length, cylindrical, a little con- 

 stricted between the anterior and posterior body , furnished 

 with 8 longitudinal ribs. The tentacles about 4'" m in 

 length. The aboral side ensheathed with spicules. The 

 pinnules well supplied with spicules. The gullet has 8 

 single series of spicules. In the basal part, bistellates and 

 clavates. In the stem, complex stellates ; and on the 

 branches, clavates, predominate. In the posterior body 

 of the polyp, clavates and complex stellates most predomi- 

 nant, and in the anterior body, large fusees the most fre- 

 quent. Colour yellow.
