Paa Forkroppen eller rettere paa Grænsen imellem 

 For- og Bagkrop ligge Spiklerne næsten horizontalt og 

 beståa væsentligst af lange, takkede Spindler, der dels ere 

 lige, dels krumme saavel i Baad- som i S Form og ere 

 fra 0.300-0.340'»™ lange og fra 0.024—0.052»"» brede. 

 Bredden er imidlertid ikke ens overalt; de lige Spindler 

 ere tykkest paa Midten, de krumme ere som oftest tykkest 

 op imod den ene Ende, Fig. 26. 27. Imellem disse store 

 Spindler sees enkelte meget smaa og tynde, lidt takkede, 

 spindelformige Spilder, der ere 0.072'»™ lange, 0.008™» 

 brede, Fig. 28. Paa selve Forkroppen antage Spindlerne, 

 der her ere meget mindre, en mere opreist Stilling, og idet 

 de slutte sig sammen, danne de 8 svagt fremstaaende 

 Længderibber, som strække sig et lidet Stykke op paa 

 Tentaklernes aborale Flade. Længere op paa denne blive 

 Spiklerne tyndere, ligge paaskraas og danne to Eækker, 

 saaledes at de indre Ender møde hverandre paa Tentak- 

 lernes Midte, og de ydre strække sig lidt udover Pinnu- 

 lerne. Disse spindelformige Spikier ere enten lige eller 

 krumme, besatte med Takker, have tilspidsede Ender og 

 ere 0.108'»™ lange, 0,008™™ brede, Fig. 29. 30. Foruden 

 Spindlerne sees paa Pinnulerne mere fladtrykte Spikier 

 med indskaarne Rande og takkede, afstumpede Ender; 

 de ere 0.064™™ lange og 0.020™'» brede, Fig. 31—33. 



Paa Svælgets ydre Flade, dækket af Epithelet og 

 omgivet af dette, fmdes 8 enkelte Længderækker Spilder, 

 der staa noget fra hverandre, Fig. 34. De ere mere eller 

 mindre fladtrykte, takkede og forskjelligt formede, ere fra 

 0.076—0.124™'» lange og fra 0.012— 0.036""» brede, Fig. 

 35—40. 



Farven. 



Stammen er svag rødlig med en i det Grønlige spillende 

 Basaldel. Grene og Polyper ere laxerøde.

Upon the anterior body or, more correctly, at the 

 margin between the anterior and posterior bodies, the 

 spicules are placed almost horizontally, and consist, prin- 

 cipally, of long spicate fusees, which, partly, are straight, 

 and partly, are bent, both, in cymbi-form, as well as in 

 S-form, and measure from 0.300 — 0.340'»™ in length, 

 and from 0.024—0.082'»™ in breadth. The breadth is^ 

 however, not uniform throughout. The straight fusees 

 are thickest at the middle, whilst the bent ones are, 

 most frequently, thickest up towards the one extremity 

 (figs. 26. 27). Amongst these large fusees, a few 

 very minute and thin, slightly spicate, fusiform spicules 

 are observed, and these measure, 0.072™™ in length, and 

 0.008™™ in breadth, fig. 28. On the anterior body, itself, 

 the fusees, which here are much more minute, assume a more 

 erect position, and as they close together, they form the 

 8 slightly projecting longitudinal series, which extend 

 a little way up the aboral surface of the tentacles. 

 Further up on this, the spicules become thinner, and are 

 placed diagonally, forming two series, in such manner, 

 that the inner extremities meet each other at the middle 

 of the tentacles, and the outer extremities extend them- 

 selves a little out over the pinnules. These fusiform 

 spicules are either straight or bent; they are beset with 

 spikes, have acuminate extremities, and measure, 0.108™™ 

 in length, and 0.008™'» in breadth (figs. 29. 30). Besides 

 the fusees, there are seen, upon the pinnules, other 

 flattened spicules with indented margins and spicate blunted 

 extremities ; they measure 0.064'"'» in length, and 0.020™™ 

 in breadth, figs. 31—33. 



On the outer surface of the gullet, covered by epi- 

 thelium and surrounded by it, 8 single longitudinal series 

 of spicules are observed, which are placed somewhat apart 

 from each other (fig. 34). They are, more or less flattened 

 spicate, and variously formed, and measure from 0.076 

 —0.124™™ in length, and from 0.012—0.036™™ in breadth 

 (figs. 35—40). 



Colour. 



The stem is faint reddish, the basal portion 

 shading to greenish. The branches, and polyps, are salmon- 

 coloured.
