Artskarakter. 



Zoanthodemet indtil 22""" høit. Stammen turet paa- 

 langs. rund, et Par Millimeter fra Grunden rundtom tæt 

 besat med (Irene, saa den næsten ganske skjules. Grenene 

 nøgne til Enden, hvor de i Regelen dele sig i 3 Smaagrene, 

 der hver bærer 6 — 7 Polvper. Disse ere cylindriske med ud- 

 videt Forkrop og en langstrakt Bagkrop, 7- 8 lange og 

 rigt besatte med takkede Spindler, bladede Koller og 

 Firlinger. Tentaklerne omtrent halvt saa lange som Kroppen 

 og paa deres aborale Side lige til Enden forsynede med 

 paatversliggende, næsten flade, takkede Spikler. Basal- 

 delens Spikler danne Klubber. Koller. Dobbeltstjerner, 

 Spindler. Valser og Firlinger. Stammen mindre rig paa 

 Spilder, men Grenene og Smaagrenene ript forsynede med 

 saadanne under Fonn af Spindler. Firlinger, Tvillinger og 

 Valser. Farven gul.

 Basaldelen er meget udvidet. fast. tyk. læderagtig. Strax 

 ovenfor Basaldelen sees enkelte, spredte, korte, tvnde 

 Grene, som dele sig i flere Smaagrene. der bære større 

 eller mindre Grupper af Polvper : men Hovedgrenene tåge 

 forst deres Begyndelse omtrent paa det Sted. hvor Stam- 

 men aftager i Tykkelse. Et Par af disse Grene ere næsten 

 ligesaa tykke som denne Del af Stammen og have en 

 Længde af indtil 25""", imedens de øvrige firene ere korte. 

 Grenene staa langt fra hverandre, ere runde, furede og

The subclavates are from 0.100—0.200""" in length. and 

 0.060""" in breadth above (hg. 68). The shaft is very 

 short in many of them (fig. 69).

Specific characteristics. 



The Zoanthodem measures up to 22""" in lieight. 

 The stem is longitudinallv grooved. cylindrical, and. from 

 a couple of millimetres above the hase. is closely beset, 

 round about, vvith branches, so that it becomes almost 

 concealed. The brancbes hare to the extremity. where 

 they usually ramify into 3 branchlets, eacb of vhich carries 

 ti — 7 polyps. These are cylindrical. with dilated anterior 

 body and an elongated posterior body, are 7 — 8""" in lengtb, 

 and richly beset with spicate fusees. foliaceous subclavates 

 and quadruplets. The tentacles are about half the length of 

 the body, and are. on their ahoral side. right out to the 

 extremity, furnished with transversal almost flat spicate 

 spicules. The spiddes of the basal part form clavates. 

 subclavates. bistellates. fusees. roller and quadruplets. The 

 stem is less rich in spicules. but the branches. and the 

 branchlets, are richly furnished with them. in the form of 

 fusees, quadruplets. twins and rollers. The colour yellow.

Pl. V. Figs. 34— RI. 



The Zoanthodem measures up to 70""" in height. 

 The stem measures. at the base, 60 mm in circumference. and 

 is cylindrical and longitudinallv grooved: it diminishes 

 in thickness rather abruptly; 45""" up, it measures only 

 about 30""' in circumference, wbilst it measures. barelv. 12'"'" 

 at the summit, where it ramifies into several branchlets 

 carrying polyps. The basal part is much dilated, firm. thick. 

 and coriaceous. Immediately above the basal part. a few 

 dispersed, short. thin branches are seen. which ramify into 

 several branchlets, carrying larger or smaller groups of 

 polyps. but the main branches first appear about the situation 

 where tbe stem diminishes in thickness. A couple of 

 these branches are almost as thick as that part of the 

 stem. and measure up to 25""" in length, wbilst the other 

 branches are short. The branches are situated far apart
