Paa Overgangen fra Coenenchymet til Polypkroppen 

 findes almindeligst takkede og bladede Spindler med konisk 

 tilspidsede eller mere afstumpede Ender; de have ofte et 

 smalt, nøgent Midtbelte og ere fra 0.192—0.284""" lange 

 og fra 0.076—0.080'"™ brede, Fig. 68. 69, .samt bladede 

 Tapper eller Køller, der ere 0.192""" lange, 0.076'"'" brede 

 i den tykke Ende, Fig. 70, og imellem de nævnte Spilder, 

 men sjeldnere, iagttages nogle, der danne Overgangsled 

 imellem Spindel, dobbelt og sammensat Stjerne og ere 

 fra 0.156—0.192""" lange og 0.092""" brede, Fig. 71. 72. 



Paa Polypkroppen, især paa dens bagerste Del, gjen- 

 findes enkelte af de Former, som nys omtaltes, samt al- 

 mindeligst Dobbeltstjerner med et nøgent Midtbelte; disse 

 ere fra 0.096—0.120'»"' lange og fra 0.052—0.056""" brede 

 i Enderne; det nøgne Midtparti er fra 0.024—0.028""'' 

 bredt, Fig. 73. 74; sjeldnere sees mere sammensatte Stjerner, 

 som ere 0.160""" lange og 0.076'"'" brede, Fig. 75. Paa 

 Forkroppen ere lange, takkede Spindler hyppigst; de ere 

 fra 0.232—0.260'"'" lange og fra 0.056—0.060""" brede, Fig. 

 76. 77. 



Paa Tentaklernes Basaldel findes Spindler,, lig dem 

 paa Forkroppen ; hengere op blive Spiklerne mindre, noget 

 fladere, men mere takkede og ere her fra 0.132 — 0.180""" 

 lange og fra 0.0-44-0.048'"'" brede, Fig. 78—81; paa 

 den øverste Del ere de ganske smaa og flade, 0.064'"'" 

 lange, 0.036""" brede, Fig. 82. 83. Paa Tentaklernes Sider 

 og paa Pinnulerne ere Spiklerne mere tynde, langtstrakte, 

 tildels stærkt takkede og indtil 0.056"»" lange, 0.008""» 

 brede, Fig. 86. 88. 



Svælget har paa begge Sider 2 Rækker Spilder, saa 

 at Bug- og Rygsiden er spikelfri, Fig. 89. Spiklerne 

 danne her dels takkede Spindler fra 0.092—0.112""" lange 

 og fra 0.024—0.040""» brede, Fig. 90, dels forskjelligt 

 formede Rosetter, der ere fra 0.072 — 0.076""" lange og fra 

 0.032—0.048'»'» brede. Fis 84. 85. 



Generationsorganerne ere udviklede i den bagerste 

 Del af Mavehulheden og strække sig tildels ned i dens 

 Forlængelser, hvor en Mængde Æg i forskjellige Utvik- 

 lingsstadier fandtes. 



Artskarakter. 



Zoanthodemet er indtil 35""" høit med en skiveformig, 

 membranøs Basaldel, der omspænder dels Anneliclerør, dels 

 Koralstumper. Stammen er tyk, aftagende lidt i Tykkelse 

 mod Toppen, der er tæt besat med Polyper, og fra dens 

 Grund og til Enden rundtom forsynet med tykke, furede 

 Grene, som ere rigt besatte med Polyper, der stundom 



At the junction of the sareosoma with the body of the 

 polyp, spicate and foliaceous fusees are, most frequently, 

 found, having conioally acuminated, or more obtuse, extrem- 

 ities ; these frequently have a narrow bare mesial belt, and 

 measure from 0.192—0.284'"'" in length, and from 0.076 

 — 0.080""" in breadth (figs. 68, 69), also, foliaceous cones or 

 siibclavates, measuring 0.192"'"' in length, and 0.076""" in 

 breadth at the thick extremity (fig. 70); and between the 

 spicules mentioned, but less frequently, may be observed, a 

 few others that form the connecting-link between the fusee 

 and the double and complex stellates, and which measure from 

 0.156—0.192""" in length, and 0.092""" in breadth (fig, 

 71. 72). 



'On the body of the polyp, especially on its posterior 

 part, a few of the forms which have just been spoken of 

 may be recognised, also, most frequently, bistellates with 

 a bare mesial belt. These measure from 0.096—0.120"»" 

 in length, and from 0.052—0.056'"'" in breadth at the 

 extremities, the bare mesial portion measuring, from 0.024 

 —0.028'"'" in breadth (figs. 73. 74); more rarely, still more 

 complex stellates may be observed, measuring from 0.160""" 

 in length, and 0.076'»'" in breadth, (fig. 75). On the 

 anterior body, long spicate fusees are, most frequently, met 

 with, and these measure, from 0.232— 0.260'"'" .in length, and 

 from 0.056-0.060'"'" in breadth (figs. 76. 77). 



On the basal portion of the tentacles, fusees are 

 found like those upon the anterior body. Further up, the 

 spicules become smaller, and somewhat flatter, but more 

 spicate, and, here, they measure, from 0.132—0.180""" in 

 .length, and from 0.044—0.048'»"' in breadth (figs. 78—81), 

 whilst on the uppermost part they are quite minute and 

 flat, and measure 0.064""" in length, and 0.036""» in breadth 

 (figs. 82, 83). On the sides of the tentacles, and on the 

 pinnules, the spicules are thinner, elongate, and sometimes 

 strongly spicate, measuring from 0.056""» in length, and 

 0.008'»'" in breadth, (figs. 86—88). 



The gullet has, on both sides, 2 series of spicules, 

 arranged in such manner, that the ventral and the dorsal 

 sides are devoid of spicules (fig. 89). The spicules form, 

 here, partly, spicate fusees measuring from 0.092— 0.112""» 

 in length, and from 0.024—0.040'""' in breadth (fig. 90). 

 partly, variously formed rosettes which measure from 

 0.072—0.076"™ in length, and from 0.032—0.048""" in 

 breadth, (figs. 84—85). 



The generative organs are developed in the posterior 

 part of the ventral-cavity, and extend themselves, partly, 

 down into its prolongations, where a mass of ova in dif- 

 ferent stages of development was found. 



Specific characteristics. 



The Zoanthodem measures up to 35'"'" in height, and 

 has a discoidally formed, membranaceous basal part, which 

 incloses, partly, annalid-tubes, partly, lumps of coral. The 

 stem is thick, diminishing a little in thickness towards the; 

 summit, which, latter, is closely beset with polyps, and 

 from the base up to the summit, it is furnished, round about
