Artskarakter. 



Zoanthodemet indtil 35""" høit. Basaldelen mem. 

 branøs. traktformigt udvidet. Stammen omtrent 25""" hoi. 

 6""" bred. hvor den udgaar fra Basalen, rund og nøgen 



i en Strækning af lic hvoretter den udvider sig til en 



Bredde af 10°"", bærende paa denne udvidede Del Poly- 

 perne. Polypcellerne staa tæt sammen, ere temmelig vide 

 med 8 stærke Ribber, adskilte ved ligesaa mange Furer- 



Polyperne omtrent 4 lange, cylindriske, retraktile, for- 



synede med 8 Ribber, imellem disse 8 svage Furer. Op- 

 imod Tentakelranden 8 triangulære, nøgne Felter, i hvis 

 Midte en Spikelrække. Tentaklerne omtrent halvt saalange 

 som Kroppen, temmelig korte og spikelrige. Pimmlerne 

 forsynede med Spikler. Svælgroret har 8 Rækker Spikler. 

 Paa Basaldelen danne Spiklerne væsentligst Dobbeltstjerner 

 og Firlinger. Paa Stammen er ligeledes Dobbeltstjernen 

 hyppigst, medens Firlingerne ere noget sjeldnere. Paa 

 Polypkroppen ere Spindler og Koller almindeligst. Farven 

 gul. Polyperne spillende lidt i det Røde. 



Skaft: de ere 0.172 lang.- og 0.048 brede foroven, 



Fig. 76. 77. De sammensatte Stjerner ere lidet udviklede; 

 Straalerne ere bladformede og ui*egelmæssige; di' ere fra 

 0.112—0.140 lange og 0.064""" luede. Fis, 78. 79. 



Paa Tentaklerne sees røsentligsl Spindler, der især 

 paa Pinnulerne ere meget tynde, næsten spydformige; imellem 

 Spindlerne sees Koller, lig dem paa Forkroppen. Spind- 

 lerne eie dels krumme, dels lige, tandede, fra 0.116 — 

 n.l 44""" lange og fra 0.012—0.028""" brede. Fig. 80. 81.

Spiklerne paa Svælgrøret have fordetmeste Spindel- 



formen; af og til sees Firlinger i Korsform. 



with leaves having dentated margins, and they have a 

 relatively short shaft; they measure 0. 172""" in length. and 



0.(148 in breadth above (Pl. XXII. fig. 7ii. 77 1. The 



complex stellates are little developed, and their rays are 

 foliform and irregular ; they measure from 0.112 — 0.140""" 

 in length, and 0.064 in breadth (Pl. XXII. figs. 78. 79). 



Upon the tentacles fusees are principally seen, whieh. 

 especially on the pinnules, are veiv thin and almost hasti- 

 iorm; between the fusees, subclavates, like tliose upon 

 the anterior body, are seen. The fusees are, partlv. eurved, 

 partly straight, and dentated; they measure from 0.116 — 



0.144 in length. and from 0.012—0.028 in breadth 



(Pl. XXII. figs. 80. 81. 82). The subclavates measure 



0.196 in length. and 0.056 in breadth above (Pl. XXII. 



fig. 83). 



The spieules on the gullet-tube have. most of them. 

 the fusiform. but nov and then a cruciform quadruplet is 

 observed. 



Colour 



The stem is pale yellowish-brown :

Habitat. 

 Station Xo. 273. Three spociraens. 



Speeirlc characteristies. 



The Zoanthodem meåsures up to 35""" in height. 

 The basal part membranaceous, dilated in infundibuliform. 



The stem meåsures about 25""" in height. and 6""" in 

 breadth at the point where it issues from the base: it is 

 cylindrical, and bare for an extent of 10""", becoming sub- 



sequently dilated to a breadth of 10 '. and the dilated 



part is occupied by polyps. The polyp-cells are plaeed 

 closelv together and are pretty wide; they have 8 strong 

 ribs separated by the same number of grooves. The 

 polyps measure about 4'"'" in length. are cylindrical, re- 

 tractile, and furnished with 8 ribs: between these ribs 

 there are 8 faint grooves. In the proximity of the teu- 

 tacular margin, there are 8 triangular bare areas in whose 

 middle a spicular series is plaeed. The tentacles measure 

 about half the length of the body; they are rather short 

 and rich in spicules. The pinnules are furnished with 

 spicules. The gullet-tube has 8 series of spicules. Upon 

 the basal part, the spicules met with are, principally, 

 bistellates and quadruplets. Upon the stem. bistellates 

 are also the most frequent spicular form, whilst quadrup- 

 lets are somewhat rarer. On the polyp-body. fusees and 

 subclavates are the most common. The colour yellow; 

 the colour of the polyps shading a little towards red.
