paa Tentaklernes Sider og mod deres Ender. Pinnulerne 

 have smaa, tynde, deis spatelformede, dels spindelformede 

 Spikler. De store Spindler ere enten lige eller krummede 

 og ere stærkt takkede. Krumningen har som oftest Baad- 

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

 paa disse ende stundom Takkerne i en liden Stjerne; de 

 ere fra 0.23b' — 0.272""" lange os 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""" lauge .og 0.044 brede foroven. Fig. 49. 



De mindre Spikler. 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 Pinuuler ere enkelte Spikler takkede og 

 fiade med indskaarne Hande, andre næsten glatte ; de ere fra 

 0.052—0.072""" lange og fra Q.008— 0.016' brede. Fig. 51. 



Svælgets Spikler ere takkede, lidt fladtrykte eig lia ve 

 hyppigst Spindelformen. Imellem Spiklerne tindes enkelte 

 brede, temmelig tiade Spikler med biede, takkede Ender; 



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



ere 0.080 lange og 0.020""" brede. Fig. 5.",. 



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 gjennemgaaende for Spiklerne hos dette Dyr. 

 Ooenenchynispiklerne ere fra 0.044—0.164""" lange og fra 

 0.020—0.048 brede. Fig. 54. 



Farven. 



Farven er gulhvid : Polvperne ere lidt morkere end 

 Stammen og spille lidt stærkere i det Gule.

Slægtskarakter. 



Stammen fattig paa Grene med en næsten kolleformet 

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

 næsten kugledannede Ender, tæt besatte med Polyper. 

 Polyperne retraktile, cylindriske. rige paa Spikler. 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 bas. usually, 

 the cymbiform, and only rarely does it approach to the 

 S-form, hut, 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. extremitv. and have spikes similar to those of the 



fusees; they measure 0.22S' in length. and o.o44 in 



breadth above (fig. 49). The smaller spicules. whieh 

 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). < hi 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 <i. 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 the v have the fusi-form. Between 

 the fusees, there are a few broad. pretty Hat. spicules, with 

 broad, spicate, extremities; they measure 0.112""" in length. 



and 0.028 in breadth (Hg. 52). The fusees measure 



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



The spicules in the sarcosimia 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 



— o.l i ".4 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 sbade a little more 

 towards vellow. 



Habitat. 



Station No. 31. Tvo specimens. 



Generie characteristies. 



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. 

 furnisbed with strong ribs, and a prominent cell. The 

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