paa Tentaklernes Sider og mod deres Ender. Pinnulerne 

 have smaa. tynde, dels spatelformede, dels spindelformede 

 Spilder. De store Spindler ere enten lige eller krummede 

 og ere stærkt takkede. Krumningen har som oftest Baad- 

 form, kun sjeldent nærmer den sig S-Formen; men ogsaa 

 paa disse ende stundom Takkerne i en liden Stjerne; de 

 ere fra 0.236—0.272""" lange og omtrent 0.040'"'" brede 

 paa Midten, Fig. 46. 47. 48. Tapperne have en tvers- 

 afskaaren, tyk Ende og lignende Takker som Spindlerne; 

 de ere 0.228""" lange og 0.044'"'" brede foroven. Fig. 49. 

 De mindre Spikier, som tindes imellem de nu nævnte, ere 

 forskjellige i Form og Størrelse, ere alle takkede og fra 

 0.064—0.104""" lange og fra 0.020— 0.040""" brede, Fig. 50. 

 Paa Tentaklernes Pinnuler ere enkelte Spikier takkede og 

 flade med indskaarne Rande, andre næsten glatte ; de ere fra 

 0.052—0.072'"'" lange og fra 0.008— 0.016""" brede. Fig. 51. 



Svælgets Spilder ere takkede, lidt flacltrykte og have 

 hyppigst Spindelformen. Imellem Spiklerne fmdes enkelte 

 brede, temmelig flade Spikier med brede, takkede Ender; 

 de ere 0.112'"'" lange. 0.028""" brede, Fig 52. Spindlerne 

 ere 0.080'""' lange og 0.020""" brede, Fig. 53. 



Spiklerne i Coenenchymet have næsten udelukkende 

 Spindelformen og ere mere eller mindre stærkt takkede. 

 Takkerne ende ofte i en liden Stjerne, en Ordning, der 

 synes at være gjennemgaaencle for Spiklerne hos dette Dyr. 

 Ooenenchymspiklerne ere fra 0.044—0.164'""' lange og fra 

 0.020—0.048'"'" brede, Fis. 54. 



Farven. 



Farven er gulhvid; Polyperne ere lidt mørkere end 

 Stammen og spille lidt stærkere i det Grille. 



Findested. 



Station 31. To Exemplarer. 



Slægtskarakter. 



Stammen fattig paa Grene med en næsten kølleformet 

 Top, rigt besat med Polyper. Grenene tykke, korte med 

 næsten kugledannede Ender, tæt besatte med Polyper. 

 Polyperne retraktile , cylindriske, rige paa Spikier, for- 

 synede med stærke Ribber og en udpræget Celle. Polyp- 

 cellerne korte, sammenvoxede. saa at der imellem dem 



spicules; these last are, however, most frequently found on 

 the sides and towards the extremities of the tentacles. 

 The pinnules carry small, thin, partly spatulate, and partly 

 fusiform spicules. The large fusees are, either, straight or 

 curved, and are strongly spicate. The curve has, usually, 

 the cymbiform, and only rarely does it approach to the 

 S-form, but, also, in these the spikes occasionally terminate 

 in a small star; they measure from 0.236 — 0.272""" in 

 length, and about 0.040"'"' in breadth at the middle (figs. 

 46. 47. 48). The coniform spicules have a truncated, 

 thick, extremity, and have spikes similar to those of the 

 fusees; they measure 0.228""" in length, and 0.044""" in 

 breadth above (fig. 49). The smaller spicules, which 

 are observed amongst those that have just been spoken of, 

 are variable in form and size, but are all spicate; they 

 measure from 0.064—0.104""" in length, and from 0.020— ■ 

 0.040""" in breadth (fig. 50). On the pinnules of the ten- 

 tacles, some spicules are spicate and flat, and have den- 

 tated margins, others, again, are almost smooth; they mea- 

 sure from 0.052—0.072""" in length, and from 0.008— 

 —0.016""" in breadth (fig. 51). 



The spicules of the gullet are spicate, and a little 

 flattened; most frequently they have the fusi-form. Between 

 the fusees, there are a few broad, pretty flat, spicules, with 

 broad, spicate, extremities ; they measure 0. 1 1 2""" in length, 

 and 0.028""" in breadth (fig. 52). The fusees measure 

 0.080""" in length, and 0.020""" in breadth (fig. 53). 



The spicules in the sarcosoma have, almost exclusively, 

 the fusiform, and are, more or less strongly, spicate. The 

 spikes frequently terminate in a small star, an arrangement 

 which appears to be universal for the spicules of this ani- 

 mal. The spicules of the sarcosoma measure from 0.044 

 —0.164""" in length, and from 0.020—0.048'"'" in breadth 

 (fig. 54). 



Colour. 



The colour is yellowish white; the polyps are a little 

 darker in colour than the stem and shade a little more 

 towards yellow. 



Habitat. 



Station No. 31. Two specimens. 



Generic characteristics. 



The stem poor in branches, has an almost subclavi- 

 form summit richly beset with polyps. The branches thick, 

 short, with nearly globular extremities closely beset with 

 polyps. The polyps retractile, cylindrical, rich in spicules, 

 furnished with strong ribs, and a prominent cell. The 

 polyp-cells short, concreted together in such manner that,
