synede med Vorter; disse Spindler ere 0.139""" lange, 

 0.044""" brede, Fig. 7. Imellem de nævnte Spindler sees 

 lige, næsten glatte Spikier, kugleformige i den ene Ende 

 og kronedannede i den anden, 0.100""" lange, 0.016""" brede 

 paa Midten, Mg. 8; korte, rosetformede Spikier med en 

 smal Basis og en bred, tornet Krone, 0.060""" lange, 

 Kronen 0.052'"" 1 bred, Fig. 9; Dobbeltstjerner, Fig. 10. 

 11, iblandt hvilke tindes enkelte med et langt, glat Midt- 

 parti, 0.120""" lange, 0.014""" paa Midten, Fig. 12;tornede 

 Køller, 0.120""" lange. 0.070""" brede i den tykke Ende, 

 Fig. 13, og endelig enkelte Firlinger i Form af Kors, der 

 dog ere sjeldne, og hvis Længdestok er 0.080""" og Tver- 

 stok 0.060""". 



Paa Stammens nederste Del træffes omtrent lignende 

 Spikier som paa Basaldelen, kun ligge de der ikke saa 

 kompakte; derimod tindes paa den øvrige Del af Stammen 

 andre Former, saaledes Dobbeltstjerner med Takker eller 

 Vorter, 0.080""" lange, 0.0 16""" brede paa Midten. Fig. 14. 

 15. 16; en Del yderst smaa Firlinger, der have et meget 

 forskjelligt Udseende, tilnærmelsesvis en Korsform, af 0.043""" 

 Længde og 0.032""" Bredde, Fig. 17. 18. 19; men foruden 

 de her nævnte Spikier, støder man ogsaa paa kj endte 

 Spikier fra Basaldelen. 



Grenene og deres Forgreninger lige indtil de tynde 

 Stilke, som bære Polyperne, ere vel forsynede med Spikier, 

 der ligge temmelig tæt uden dog at komme i Berørelse 

 med hverandre, Fig. 3, kun paa enkelte Steder hænder det, 

 at Spiklerne have samlet sig i smaa Grupper. Takkede 

 Spindler, dels krumme, dels lige med tilspidsede eller af- 

 stumpede Ender ere de hyppigste, Fig. 20 — 24. De 

 variere noget i Størrelse, fra 0.120—0.240'"'" lange og fra 

 0.020 — 0.040'"'" brede. Imellem dem sees enkelte, takkede 

 Valser, 0.120""" lange, 0.040""" brede, Fig. 25, — enkelte 

 Køller med stærke Takker, 0.200'"™ lange, 0.040'"™ i den 

 brede Ende, Fig. 26, samt korsformede, takkede Firlinger 

 med en- Længdestok, 0.120""", og en Tverstok, 0.060™"', 

 Fig: 27. 28. 



Paa Polypkroppens bagerste Del, hvor den gaar over 

 i Stilken, sees omtrent lignende Spikier som de, der ere 

 antydede paa Smaagrenene og Stilkene, dog iblandet enkelt- 

 vis med andre, der tilhøre den øvrige Del af Kroppen. 

 Paa denne variere Formerne særdeles meget. Takkede, 

 krumme og lige Spindler af samme Størrelse som de paa 

 Smaagrenene, tildels meget tyndere, Fig. 29. 30. 31, samt 

 takkede, lige Køller, 0.140""" lange, 0.040""" i den brede 

 Ende, Fig. 32, ere de almindeligste ; sjeldne ere takkede 

 Valser, Fig. 33. 34, og yderst sjeldent forgrenede Spilder, 

 Fig. 35, men ikke saa ganske sjeldent træffes hist og her 

 forskjellige Firlinger, der dog alle have antaget Korsformen: 



far apart from each other, or prolongations furnished with 

 warts; these fusees measure 0.139'"™ in length, and 0.044"™ 

 in breadth (fig. 7). Between the fusees mentioned, are ob- 

 served, straight and almost smooth spicules, spheri-form in 

 the one extremity and coroni-form in the other, mea- 

 suring 0.100"™ in length, and 0.016"™ in breadth at the 

 middle (fig. 8); short, rosetti-form spicules, with a nar- 

 row base and a broad aculeated corona, measuring 

 0.060""" in length, and the corona 0.052""" in breadth 

 (fig. 9); bistellates (figs. 10. 11) amongst which are 

 found a feAv with a long smooth medial part, and mea- 

 suring 1.120"™ in length, and 0.014""» at the middle (fig. 12); 

 aculeated subclavates, measuring 0.120'""' in length, and 

 0.070""" in breadth at the thick extremity (fig. 13); and finally, 

 a few cruciform quadruplets, which, however, are rare, and 

 whose longitudinal arm measures 0.080""" and the trans- 

 versal arm 0.060""" in length. 



In the lowest part of the stem we meet with spicules, 

 having about the same forms as those of the basal portion, 

 only, that there, they are not placed so compactly. On 

 the other hand, upon the rest of the stem we find other 

 forms, such as bistellates with spikes, or warts, and 

 measuring 0.080"™ in length, and 0.016""" in breadth at 

 the middle (figs. 14. 15. 16); further, a number of extremely 

 minute quadruplets which have a very variable appearance, 

 approaching, approximately, to the cruciform and measuring 

 0.043""" in length, and 0.032"™ in breadth (figs 17. 18. 19) ? 

 but besides the spicules, here, mentioned, we meet with 

 familiar spicules like those of the basal part. 



The branches and their ramifications, including even 

 the thin stalks that carry the polyps, are well supplied 

 with spicules, which are placed rather close without, 

 however, coming into contact with each other (fig. 3) ; in 

 a few places only does it happen that the spicules collect 

 themselves into small groups. The most frequent forms 

 are spicate iusees, partly bent, partly straight, with acumi- 

 nated or blunted extremities (figs. 20 — 24). They vary 

 somewhat in size, measuring from 0.120 — 240"™ in length, 

 and from 0.020 — 0.040"™ in breadth. Between them, are 

 visible, a few spicate rollers, measuring 0.120"™ in length, 

 and 0.040""" in breadth (fig. 25) ; occasional subclavates with 

 strong spikes and measuring 0.200""" in length, and 0.040""" 

 in breadth at the broad extremity (fig. 26); also, cruciform 

 spicate quadruplets, with a longitudinal arm measuring 

 0.120'"'" and a transversal arm 0.060™'" (figs. 27. 28) 



On the posterior part of the body of the polyp, 

 where it becomes produced into the stalk, spicules are 

 observed of about the same kind as those indicated as 

 pertaining to the branchlets and the stalks, but inter- 

 spersed, occasionally, with others that pertain to the 

 remaining part of the body. On this, the forms vary 

 in a great degree. Spicate, bent and straight, fusees 

 of same size as those of the branchlets but, partly, much 

 thinner (figs. 29. 30. 31) and also, spicate, straight subclavates 

 measuring 0.140'"™ in length, and 0.040""" in breadth at the 

 broad extremity (fig. 32) are the most frequent, rarely do 

 we find spicate rollers (figs. 33. 34), and extremely rarely
