satte Stjerner have brede, takkede Straaler med nøgne 

 Rum imellem Straalebundterne ; de ere 0.184""" lange. 0.104""" 

 brede foroven, Fig. 08. Dobbeltstjernerne ligne noget de 

 paa Basaldelen, og Straalerne ende gjerne i en liden Stjerne; 

 de ere 0.132»"" lange. 0.076'"'" brede i Enderne og 0.026""" 

 brede paa Midten; Fig. 69. 70. Klubberne ere større og 

 rigere besatte med Blade, end de paa Basalen; de ere 

 0.2 16»»» lange. 0.124"»" brede foroven. Fis;. 71. 



Paa Grenene ligge Spiklerne ligesom paa Stammen 

 tæt paa hverandre, og Formerne ere her væsentlig Klubber, 

 der ere 0.176""" lange og 0.108""" brede foroven og have 

 brede, tandede Blade, Fig. 72. Imellem Klubberne sees 

 dels enkelte Dobbeltstjerner, dels Bosetter og dels særegne, 

 bladbesatte Spikier. Bosetterne ere omtrent lige brede 

 som lange, 0.132""" i Gjennemsnit, Fig. 73. De særegne 

 Spikier ere 0.216""» lange, 0112""" brede, Fig. 74. 



Paa Polypernes Bagkrop ere Klubber og sammen- 

 satte Stjerner almindeligst, Dobbeltstjerner og Firlinger 

 sjeldnere. Klubberne ere forsynede med brede, i Randen 

 tandede Blade; de ere fra 0.140 — 0.168'"'" lange og fra 

 0.084— 0.096 mm brede foroven, Fig. 75. 76. De sammen- 

 satte Stjerner variere noget; nogle nærme sig Dobbelt- 

 stjernen med et nøgent Midtparti, ere 0.1 76""" lange, 

 0.076"'"' brede med 0.036""" bredt Midtbelte, Fig. 77; 

 andre have næsten Spindelformen, have tandede Straaler og 

 ere 0.168""" lange, 0.050""" brede, Fig. 78. Firlingerne 

 ere dels i Kors-, dels i Rosetfbrm og rigt ornamenterede 

 med Blade og Takker. De korsformede ere fra 0.124 — 

 0.128'"'» lange med en Tverstok fra 0.116— 0.132»"», Fig. 79. 

 80. Rosetten er 0.172»"" låna;. 0.120""" bred. Fig. 81. 



Paa Forkroppen er Spindelformen den dominerende; 

 Klubber ere her sjeldnere og sammensatte Stjerner sees kun 

 enkeltvis. Spindlerne ere i Reglen rigt besatte med Blade, 

 der have takkede Rande. De ere dels krumme, dels lige, 

 enten tilspidsede eller mere eller mindre afstumpede i 

 Enderne; de ere fra 0.172—0.516""» lange og fra 0.048— 

 0.100""» brede paa Midten, Fig. 82. 83. 84. Klubberne 

 ere noget forskjellige fra dem paa Bagkroppen, de ere nem- 

 lig mere langstrakte, og Bladene synes at være mindre; de 

 ere 0.200"»" lange og 0.072'""' brede foroven. Fig. 85. 



Paa Tentaklerne ligge Spiklerne meget kompakte, 

 ere noget fladere end paa Kroppen og have forskjellig 

 Form ; enkelte ere næsten spydformede, andre spatelfor- 

 mede, atter andre nærme sig Spindelen. De spydformede 

 ere svagt takkede, 0.144""" lange, 0.028'""' brede, Fig. 86; 

 de spateldannede rage mest ind i Pinnulerne, have takkede 



lates appear. The complex stellates have broad spicate 

 rays, with bare spaces appearing between the bundles of 

 rays; they measure 0.184""" in length, and 0.104""" in breadth 

 above (fig. 68). The bistellates resemble, somewhat, those 

 of the basal part; the rays terminate, often, in a small 

 star; they measure 0.132""" in length, and 0.076""" in 

 breadth at the extremities, and 0.036™'" in breadth at the 

 middle (figs. 69. 70). The clavates are larger, and more 

 richly beset with leaves than those of the basal part; they 

 measure 0.216""" in length, and 0.124""" in breadth above 

 (fig. 71). 



On the branches, the spicules are placed, as in the 

 stem, closely upon each other, and the forms met with 

 here, are, principally, clavates measuring 0.17 6 ,nm in length, 

 and 0.108""" in breadth above, and having broad dentated 

 leaves (fig. 72). Between the clavates, there are seen, 

 partly, a few bistellates, partly, rosettes, and partly, pecu- 

 liar leaf-covered spicules. The rosettes are about as 

 broad as they are long, and measure 0.132""" in diameter 

 (fig. 73). The peculiar spicules measure 0.216""" in length, 

 and 0.112""" in breadth (fig. 74). 



In the posterior body of the polyps, the clavate and 

 complex stellates are the most frequent spicular forms, the 

 bistellates and quadruplets being less frequent. The clav- 

 ates are adorned with broad leaves dentated in the margins, 

 and measure from 0.140— 0.l68 mm in length, and from 0.084 

 — 0.096""" in breadth above (fig. 75. 76). The complex 

 stellates vary somewhat, a few approach in form to the 

 bistellates, and have a bare middle part; they measure 

 0.176'""' in length, and 0.076'"'" in breadth, and have a 

 middle stripe measuring 0.036"'"' in breadth (fig. 77). Others 

 are almost fusiform; these have dentated rays, and mea- 

 sure 0.168'""' in length, and 0.050""». in breadth (fig. 78). 

 The quadruplets are, partly, cruciforms, and partly, rosetti- 

 forms, and they are richly adorned with leaves and spikes. 

 The cruciforms measure, from 0.124 — 0.128""" in length, 

 and have a transversal arm measuring from 0.116 — 0.132""" 

 (figs. 79. 80)- The rosettiforms measure 0.172"'"' in length, 

 and 0.120'"»' in breadth (fig. 81). 



On the anterior body, the fusee is the predominant 

 spicular form; clavates are. here, less frequent, and com- 

 plex stellates are seen only exceptionally. The fusees are, 

 as a rule, richly beset with leaves having spicate margins. 

 They are, partly, curved, partly, straight, either acuminated 

 or more less blunted at the extremities ; they measure 

 from 0.172—0.516»»» in length, and from 0.048—0.100"»" 

 in breath at the middle (figs. 82. 83. 84). The .clavates 

 are somewhat different from those on the posterior body; 

 they are, for instance, more elongate, and the leaves ap- 

 pear to be smaller; they measure 0.200'""' in length, and 

 0.072»"" in breadth above (fig. 85). 



On the tentacles, the spicules are placed very com- 

 pactly, and they are somewhat flatter than ; those on the 

 body, and have a different form. A few are almost spear- 

 shaped, others are spatula-shaped, whilst others, again, 

 approach to the fusiform. The spear-shaped skules are 

 faintly spicate; they measure 0.144""" in length, and
