Hele Zoanthodemet er meget rigt paa Spilder. Paa 

 Stammen og Grenene fincles: bladbedækkede Køller, der 

 stundom ere delte i øverste Ende og ere 0.14O"" lange 

 og 0.080 mm brede noget over Midten, Fig. 18. 19. 20; 

 Dobbeltstjeraer lige brede som lange, 0.060""" i Grjen-

 Bagkrop, især der, hvor den gaar over i Coenenchymet, ligge 

 Spiklerne paatvers, Fig 16, a, og optræde under forskjel- 

 lige Former, hvoriblandt gjenkjendes flere af dem fra 

 Stammen og Grenene; men hyppigst træffes dog Valser

 korsformede Firlinger besatte med Takker, indtil 0.180""»

 Forkroppen staa Spiklerne næsten oprette i 8 Dobbelt- 

 rækker, Fig. 16, b, og dannes væsentligst af stærkt tak- 

 kede Spindler, der dels ere lige med næsten tilspiclsede 

 Ender, 0.400'""' lange, 0.035'»"' brede, Fig. 28, dels lidt 

 krumme, næsten baadformige, 0.380""" lange, 0.040""" brede,

 Spilder af Køllens Længde, Fig. 33. 



Tentaklerne ere tæt besatte med 2 Eækker paaskraas 

 gaaende Spikier, Fig. 16, c. 17, hvoraf Størstedelen danner 

 takkede, dels lige, dels krumme Spindler, med snart spidse, 

 snart afstumpede Ender og ere 0.220""" lange, 0.016'".'"

 Køller, 0.120"'™ lange, 0.032""" brede i den brede Ende,. 

 Fig 36. Paa Pinnulerne danne Spiklerne dels takkede 

 Køller, Fig. 37, dels takkede Spilder, der ere meget smaa, 

 0.020""" lange, 0.012""" brede, Fig. 38, hvorimellem iagttages 

 større, noget fladtrykte, lidt takkede Spikier med brede, 

 takkede Ender, 0.024 mm brede, Fig. 39, samt nogle korte, 

 tynde, takkede, lige Spindler, 0.060"™ lange, 0.008""» brede, 

 Fig 40. 



Svælget er forsynet med 8 Dobbeltrækker Spilder, der

and are, likewise, on their aboral surface, sheathed with 

 spicules (fig. 16. 17). The oral-disk is slightly convex, 

 and the oral aperture forms a transversal fissure. 



The entire Zoanthodem is very rich in spicules. On 

 the stem and the branches, foliaceous subclavates are found, 

 which are sometimes ramous in the uppermost extremity. 

 They measure. 0.140'""' in length, and 0.080""» in breadth 

 a little above the middle (figs. 18. 19. 20). The bi-stel- 

 lates are as broad as they are long, and measure, 0.060""" 

 in diameter (fig. 21). There are a few cruciform quadruplets, 

 roller -formed spicules beset with warts, and measuring 

 0.140""" in length, and 0.070""" in breadth at the middle 

 (figs. 22. 23), and finally, spicate fusees measuring 0.060"™ 

 in length, and 0.020'"'" in breadth (figs. 24. 25). On the 

 posterior body of the polyp, especially at the point where 

 it is produced into the sarcosoma, the spicules are placed 

 transversally (fig. 16, a) and appear in various forms, 

 amongst which may be recognised several like those of 

 the stem and the branches; but most frequently, however, 

 rollers beset with warts are met with (figs. 22. 23) and 

 very complex stellates, richly beset with spikes, and meas- 

 uring 0.136'" m in length, and 0.080" m in breadth at the 

 middle (fig. 26) between which, there are, here and there, 

 seen, cruciform quadruplets beset with spikes, and meas- 

 uring up to 0.180'"'" in length, and the transversal arm 

 measuring up to 0.100'"'" (fig. 27). On the anterior body, 

 the spicules are placed almost erect, in 8 double-series, 

 (fig. 16, 6) and are formed, principally, of strongly spicated 

 fusees, which, partly, are straight, with almost acuminated 

 extremities, and measure 0.400""" in length, and 0.035""" 

 in breadth (fig. 28) partly, slightly bent, almost cymbiform 

 fusees, measuring 0.380'"'" in length, and 0.040""" in breadth 

 (figs. 29. 30). Between these, a few elongate cruciform 

 quadruplets appear, measuring 0.264""" in length, and having 

 a transversal arm. 0.072""" in length (fig. 31) also, spicate sub- 

 clavates measuring, 0.144""" in length, and 0.020""" in breadth 

 superiorly (fig. 32), and finally, elongate, spicate, straight 

 spicules, of same length as the subclavates (fig. 33). 



The tentacles are closely beset with 2 series of 

 diagonally placed spicules (figs. 16 c, 17) of which, the 

 greater number form spicate, partly straight, partly bent 

 fusees, sometimes with acuminate, and sometimes with 

 blunted extremities, and measuring 0.220""" in length, and 

 0.016'"'" in breadth at the middle (figs. 34. 35). Amongst 

 these, spicate subclavates are seen, measuring 0. 120""" in length, 

 and 0.032'""' in breadth at the broad extremity (fig. 36). 

 Upon the pinnules, the spicules form, partly, spicate 

 subclavates (fig. 37) partly, spicate spicules which are very 

 minute, measuring 0.020""" in length, and 0.012 in breadth 

 (fig. 38) between Avhich, there may be observed, largish, 

 somewhat flattened, slightly spicated spicules, with broad 

 spicate extremities, and measuring 0.140""" in length, and 

 0.024""" in breadth (fig. 39) .also, a few short, thin, spi- 

 cate straight fusees, measuring 0.060""" in length, and 

 0.008'"'" in breadth (fig. 40). 



The gullet is furnished with 8 double series of 

 spicules, which consist of spicate fusees with acuminated
