Nederst paa Stammen ligge Spiklerne tæt sammen 

 aden at ligge paa hverandre; almiiideligst er her Dobbelt - 

 stjernen, kun yderst sjelden træftes en Spindel. Dobbelt- 

 stjernerne ere her rigere paa Straaler end de paa 

 Basaldelen. ligesom Midtpartiet oftere er besat med Vorter 



eller Takker: de ere fra 0.128—0.140 lange, fra 0.104 



—0.112""" brede i Enderne ; Midtpartiet er dels 0.032 



bredt, Fig. 13. dels er det saa optaget af Vorter, at det 

 er na-sten lige saa bredt som Enderne, Fig. 14. Spind- 

 Jerne ere meget takkede med afstumpede, brede Ender; de 

 ere Hue og krumme om hinanden og ere 0.128""" lange, 



0.048 brede. Fig. 15. Midt paa Stammen ligge Spiklerne 



ikke saa tæt sammen som paa den nederste Del; Dobbelt- 

 stjernerné med mange Straaler og et nøgent Midtbelte ere 

 de almindeligste ; yderst sjeldent sees en Firling. Dobbelt- 



stjernerne ere fra 0.088— 0.136 lange, fra 0.068—0.096 



brede i Enderne, og fra 0.032 — 0.044""" brede paa Midten, 

 Fig. 16— IV. Firlingerne nærme sig ligesom paa Stammens 

 nederste Del enten Korsformen eller Dobbeltstjernen, Fig. 

 20. 21; de ere fra 0.096—0.128""" lange, fra 0.080—0.088""" 

 brede. Jo længere op paa Stammen, man kommer, jo 

 niere spredte ligge Spiklerne. men Dobbeltstjerneformen 

 er ogsaa her gjennemgaaende. 



Paa Grenene, især de tykkeste, ligge Spiklerne lige 

 saa tæt som paa Stammens Midtparti. Stjerneformen 

 er den hyppigste, men noget forskjellig fra den, jeg tidligere 

 har omtalt. Spiklerne ere i det Hele tåget betydelig 

 mindre, fra 0.048—0.082""" lange, fra 0.028—0.044™" 

 brede i Enderne og fra 0.008—0.024""" brede paa Midten: 

 Straalerne ere enklere, Midtpartiet i Regelen mere lang- 

 strakt, Fig. 22 — 26. En Firling, nærmende sig Dobbelt- 

 stjernen, er meget sjelden; den er omtrent lige lang som 

 bred med et tornet Midtparti, Fig. 27. 



Paa Smaagrenene eller Stilkene ere Spiklerne yderst 

 sparsomme; de ere enkle- i Formen, meget smaa og have 

 en mørkegul Farve. De hyppigste ere Klubber, næsten 

 glatte; de ere omtrent lige store, 0.056""" lange, 0.028""" 

 brede i den tykke Ende. Skaftet er kort og afrundet. 

 Fig. 28 — 3U. Foruden disse sees en, der ligner en Dobbelt- 



stjerne, 0.076 lang, 0.044""" bred i Enderne, 0.024 



bred paa Midten, Fig. 31 ; men saa fattig Spikeldannelsen 

 er paa disse Smaagrene, saa meget rigere bliver den, 

 strax Polyperne optræde. 



Paa Polypens Bagkrop ligge Spiklerne paatvers i 



Længderækker og vise sig under Form af Spindler, Valser 

 og Dobbeltstjerner. Spindlerne ere meget takkede, have 

 afstumpede, takkede Ender og ere for det meste lige; de 

 ere fra 0.104—0.120""" lange og fra 0.040— 0.044""" brede, 



At the foot of the stem. the spieules are placed 

 close together without, however, lying upon each other; 

 in this situation, the bistellate form usually appears; 

 only extivnielv rarelv is the fusee met with. The bistel- 

 lates are. here, richer in ravs than those of the basal part. 

 wbilst, the mesial part is frequently occupied by warts 

 or spikes: they measure from 0.128 — 0.140""" in length, 

 and from 0.104 — 0.112""" in breadth at the extremities; 



the middle part measures 0.032' in breadth (fig. 13), and 



is. partly, so occupied by warts, that it is almosl as broad 

 as the extremities (rig. 14). The fusees are much spicated, 

 have obtuselv rounded, broad. extremities. and are, sometimes 

 straight, and sometimes bent; they measure 0.128'"'" in 



length, and 0.048 in breadth ('fig. 15). In the middle 



of the stem. the spieules are not placed so closely together 

 as upon the lowest part; the bistellates with numerous 

 ravs and a bare mesial belt are the most usual forms; 

 only very rarelv is a quadruplet seen. The bistellates 

 measure from 0.088 — 0.136""" in length, from 0.068 — 

 0.096""" in breadth at the extremities, and from 0.032— 



0.044 in breadth at the middle (figs. 16—19) 



The 



quadruplets approach, like those of the lowest part of 

 the stem. either to the cruci-form, or to the bistellate 



form (figs. 20. 2\): they measure from 0.096 — 0.128 ' in 



length, and from 0.080—0.088 in breadth. The further 



up the stem we approach. the more dispersed do the 

 spieules become, but the bistellate fonn is, also, here. met 

 with throughout. 



Upon the branches, especially the thickest ones, the 

 spieules are as close-set as upon the middle part of the 

 stem. The stellate form is the most frequent, but some- 

 what different from that I have previously spoken of. 

 The spieules are. altogether, considerably smaller. mea- 



suring from 0.048—0.082""" in length, from 0.028—0.044 



in breadth at the extremities, and from 0.088—0.024 



in breadth at the middle. The ravs are plainer. and the 

 middle part is. usually, more elongate (figs. 22 — 26). A 

 ijuadruplet approaching to the bistellate form is but rare; 

 it measures about as long as it is broad, and has an 

 aculeated mesial part (fig. 27). 



On the small branches or stalks, the spieules appear 

 extremely sparingly; they are plain in form, and have a 

 dark yellow colour; they are most frequently clavates. 

 are almost smooth, and about uniform in size, measuring 



0.056 in length and 0.028 in breadth at the thick 



extremity. The shaft is short and rounded (figs. 28 — 30). 

 Besides these, one resembling a bistellate is observed, 



and it measures 0.076 ' in length. 0.044""" in breadth at 



the extremities. and 0.024""" in breadth at the middle 

 (fig. 31 1 ; but however poor the spicular formation is upon 

 these small branches, so much the richer does it become 

 whenever the polyps appear. 



On the posterior body of the polyps, the spieules are 

 situated transversally, in longitudinal series, and appear in 

 the form of jfusees, rollers, and bistellates. The fusees 

 are veryspicate, and have blunted spicate extremities; they 

 are usually straight and measure from 0.104 — 0.120'"'"
