som ende i mange Blade.; de ere 0.088""" lange, 0.064"™ 

 brede i Enderne, paa Midten 0.020"™. Seet ovenfra eller 

 paaskraas have mange af disse Dobbeltstjerner et smukt 

 straalet Udseende, Fig. 5.5. Meget sjeldnere træffes mere 

 sammensatte Stjerner, der ere 0.148"™ lange, 0.102'"» 

 brede, paa Midten 0.036""», Fig. 6; men endnu sjeldnere 

 sees Firlinger, dels i Form af Kors, dels som Rosetter. 

 Den korsformede Firling er 0.156™" lang med en 0.124"™ 

 bred Tverstok, Fig. 7; Bosetterne . ere 0.104™" lange, 

 0.080"»» brede, Fig. 8. Formlen de ovennævnte Spikel- 

 former sees ogsaa enkeltvis forunderlige Spilder med bladede 

 Udvæxter, hvilke synes at være Afændringer af Dobbelt- 

 stjernen; de ere 0.116""" lange, 0.068"™ brede mod Enderne 

 og 0.028"™ bred omtrent paa Midten, Fig. 9. 



Paa Stammen lindes for en stor Del lignende Dobbelt- 

 stjerner som paa Basaldelen, men i Regelen rigere orna- 

 menterede og noget større; de ere fra 0.096 — 0.128""" lange 

 og fra 0.072— 0.080""" brede i Enderne og med et Midt- 

 parti fra 0.024— 0.036""" bredt, Fig. 10. Imellem disse 

 Spikier sees en og anden Spindel besat med Blade, 0.120""" 

 lang, 0.060""" bred, og som nærmer sig meget til den 

 sammensatte Stjerneform, Fig. 11. 



Paa Grenene træffes atter Dobbeltstjerner almindeligst, 

 men som man vil se af Figurerne, ere de her noget for- 

 skjellige, idet Enderne ere rigere paa Straaler; de ere fra 

 0.100—0.120""" lange og fra 0.060—0.076'"'» brede og fra 

 0.024 — 0.032""" brede paa Midten, der i Regelen er nøgen, 

 Fig. 12 — 17. Ikke saa sjeldent sees imellem de nævnte 

 Dobbeltstjerner store, tilspidsede Spindler, besatte med' 

 Blade, der ere 0.168'"'" lange, 0.064""» brede paa Midten, 

 Fig. 18, og meget sammensatte Stjernespikler, 0.240""" 

 lange, 0.108""" brede paa Midten, Fig. 19; men særdeles 

 sjeldent iagttages Firlinger, der dels nærme sig Timeglas- 

 formen og ere 0.142""" lange, 0.096""" brede i Enderne og 

 0.036"™ bred paa Midten, Fig. 20, dels Korsformen og ere 

 fra 0.100—0.128'»"' lange med en Bredde fra 0.088—0.104'»"', 

 Fig. 21. 22. 



Paa Polypens Bagkrop ligge Spiklerne paatvers i 8 

 Længderækker, Fig 2, og beståa dels af Dobbeltstjerner, 

 0.140""" lange, 0.076""" brede i Enderne og 0.032""» brede 

 paa Midtpartiet, der som oftest er nøgent, Fig. 23, dels 

 af takkede, lidt fladtrykte Spindler med mere eller mindre 

 tversafskaarne Ender, der ere fra 0.120 — 0.164""" lange og 

 fra 0.076""" brede, stundom ere de indknebne paa Midten, 

 Fig. 24. 25. 



part (fig. 4) but, most frequently, that part is short, whilst 

 from both extremities, rays proceed, terminating in numer- 

 ous leaves. They measure 0.088""" in length, 0.064""" in 

 breadth at the extremities, and 20""" in the middle. 

 Viewed superiorly or diagonally, many of these bistel- 

 lates have a beautiful radiated appearance (figs. 5.5). Much 

 more rarely do we meet with more complex stellates, meas- 

 uring 0.148""» in length, and 0.102'""' in breadth, and 

 0.036""" in the middle (fig. 6) but still more rarely are 

 quadruplets seen, partly cruciform, and partly, rosetti- 

 form. The cruciform quadruplet measures 0.156""" in 

 length, and has a 0.124""" broad transversal arm (fig. 7). 

 The rosettes measure 0.104""» in length, and 0.080"'"' in 

 breadth (fig. 8). Besides the above named spicular forms, 

 there are, also, seen, occasional strange spicules with 

 foliaceous excrescences; these seem to be modifications 

 of the bistellate, and measure 0.116""" in length, and 

 0.068""" in breadth towards the extremities, and 0.028""" 

 broad at the middle (fig. 9). 



On the stem, there are> in large measure, found, simi- 

 lar bistellates to those of the basal part but, as a rule, more 

 richly embellished, and somewhat larger; they measure 

 from 0.096—0.128""" in length, and from 0.072—0.080""" 

 in breadth at the extremities, with a mesial portion measuring 

 from 0.024—0.036""" in breadth (fig. 10). Between these spi- 

 cules, an occasional fusee beset Vvith leaves is seen, meas- 

 uring 0.120""" in length and 0.060""" in breadth; it 

 much approaches to the complex stellate-form (fig. 11) . 



Upon the branches, the bistellate is again met 

 with, usually, but, as one can see from the illustrations, 

 they are, here, somewhat different in aspect, in as much 

 that the extremities are richer in rays; they measure from 

 0.100—0.120""" in length, from 0.060—0.076""" in breadth, 

 and are from 0.024—0.032""" broad at the middle, which, 

 usually, is bare (figs. 12 — 17). Between the bistellates 

 spoken of, there are seen, not infrequently, large, acumi- 

 nated fusees beset with leaves, and measuring 0.168""" in 

 length, and 0.064""» in breadth at the middle (fig 18); 

 and also, very complex stellate-spicules, measuring 0.240""" 

 in length, and 0.108""" broad at the middle (fig. 19), 

 but exceptionally rarely are quadruplets observed, which, 

 partly, approach to an hour-glass in form, and measure 

 0.142""" in length, and 0.096'"'" in breadth at the extrem- 

 ities, and 0.036""" broad at the middle (fig. 20) and 

 partly, are cruciform, measuring from 0.100 — 0.128""" in 

 length, with a breadth of from 0.088—0.104"'"' (figs. 21. 22). 



On the posterior body of the polyp, the spicules are 

 placed transvers ally, in 8 longitudinal series (fig. 2) and 

 consist, partly, of bistellates, measuring 0.140"™ in length, 

 and 0.076""" in breadth at the extremities, and 0.032"™ 

 in breadth at the middle part, which, most frequently, is 

 bare (fig. 23), and partly, of spicate, slightly flattened, 

 fusees with, more or less, truncated extremities, and meas- 

 uring from 0.120—0.164""" in length, and from 0.056— 

 0.076""" in breadth; occasionally, they are constricted at 

 the middle (figs. 24. 25).
