Artskarakter. 



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

 langs, rund. et Par Millimeter fra Grunden rundtom tæt 

 besat med Grene, saa den næsten ganske skjules. Grenene 

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

 der liver bærer 6 — 7 Polyper. Disse ere cylindriske med ud- 

 videt Forkrop og en langstrakt Bagkrop, 7— S mm lange og 

 rigt besatte med takkede Spindler, bladede Køller og 

 Firlinger. Tentaklerne omtrent halvt saa lange som Kroppen 

 og paa deres aborale Side lige til Enden forsynede med 

 paatversliggende, næsten flade. takkede Spikier. Basal- 

 delens Spilder danne Klubber, Køller. Dobbeltstjerner, 

 Spindler, Valser og Firlinger. Stammen mindre rig paa 

 Spikier, men Grenene og Smaagrenene rigt forsynede med 

 saadanne under Form af Spindler, Firlinger. Tvillinger og 

 Valser. Farven gul.

Zoanthodemet er indtil 70""" høit. 'Stammen er ved 

 Grunden 60""" i Omkreds, rund og furet efter Længden, 

 men aftager temmelig pludselig i Tykkelse, idet den 45""" 

 opad er kun henved 30""" i Omfang og i Toppen knapt 12™™, 

 hvor den deler sig i flere Smaagrene, bærende Polyper. 

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

 ovenfor Basaldelen sees enkelte, spredte, korte, tynde 

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

 eller mindre Grupper af Polyper; men Hovedgrenene tåge 

 først 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 Grene ere korte. 

 Grenene staa langt fra hverandre, ere runde, furede og 

 dele sig i Regelen nogle Milimeter fra Stammen i 2 mindre 



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

 6.060""" in breadth above (fig. 68). The shaft is very 

 short in many of them (fig. 69).

Specific characteristics. 



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

 The stem is longitudinally grooved, cylindrical, and, from 

 a couple of millimetres above the base, is closely beset, 

 round about, with branches, so that it becomes almost 

 concealed. The branches bare to the extremity, where 

 they usually ramify into 3 branchlets, each of which carries 

 6 — 7 polyps. These are cylindrical, with dilated anterior 

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

 and richly beset with spicate fusees, foliaceous subclavates 

 and quadruplets. The tentacles are about half the length of 

 the body, and are, on their aboral side, right out to the 

 extremity, furnished with transversal almost flat spicate 

 spicules. The spicules 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. 



Duva glacialis, n. sp. 



Pl. Y. Figs. 34—81. 



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

 The stem measures, at the base ; 60""" in circumference, and 

 is cylindrical and longitudinally grooved; it diminishes 

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

 about 30'"'" in circumference, whilst it measures, barely, 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 the 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, whilst the other 

 branches are short. The branches are situated far apart
