glat, langt Skaft, omtrent af samme Længde som Dobbelt- 

 stjernerne, Fig. 37, og takkede, tornede, lige eller krumme 

 Spindler med dels afrundede, dels takkede, dels mere eller 

 mindre tilspidsede Ender, fra 0.100—0.140""" lange og fra 

 0.012—0.016"»" brede, Fig. 38. 39. 40. Hist og her, men 

 kun sjeldent, sees imellem de nævnte Spikier enkelte Fir- 

 linger, besatte med smaa Papiller, og 0.080""" lange, 0.060""" 

 brede, Fig. 41. 



Polypkroppens Spikier ere meget forskjellige. Ue al- 

 mindeligste ere takkede Spindler, dels med stumpe, dels med 

 tilspidsede Ender, fra 0.120—0.200""" lange og fra 0.020— 

 0.040'""* brede, Fig. 42. 43, samt takkede og vortede Køller, 

 fra 0.140—0.180""" lange og fra 0.040—0.080""" brede i 

 den øverste Ende, der stundom kan være tvers afskaaren og 

 da ligeledes besat med Vorter, Fig. 44. 



Imellem de nævnte Spikier træffes ofte snart Tvillinger, 

 snart Firlinger. Tvillingerne ere dels takkede, dels turnede, 

 næsten flade med takkede Ender og lidt indknebne paa 

 Midten; de ere af forskjellig Størrelse, fra 0.050 — 0.080 mm 

 lange og fra 0.010—0.020""" brede, Fig. 45. 46. Firlingerne 

 antage mere eller mindre Korsformen; enkelte af dem ere 

 temmelig flade, men alle ere besatte med større og mindre 

 fremspringende Takker; nogle ere næsten lige brede som 

 lange; deres Gjennemsnit er indtil 0.0120""", andre ere mere 

 langstrakte og da 0.080""" lange, 0.040""" brede, Fig. 

 47 — 51; men saa sjeldne ere vel udprægede Kors, at paa 

 en hel Polypkrop iagttoges kun et enkelt, hvis Længde- 

 stok var 0.160'"'" oe- Tverstok 0.040""", Fiff. 52. 



Farven. 



Hele Zoanthodemet er violet, dog saaledes at Stammen 

 og Grenene spille lidt i det Gule. Polyperne ere intens 

 violerte. 



Findested. 



Station 359. Et Exemplar. 



Artskarakter. 



Zoanthodemet indtil 80'"'" høit. Stammen deler sig et 

 lidet Stykke ovenfor Grunddelen i to, hvoraf den ene er 

 lidt tykkere, end den anden. Basaldelen 70'"'" i Omkreds, 

 og fra den udspringe et Par yderst korte, tyncle Grene, 

 paa hvis Ender lindes 3 — 4 Polyper. Fra de 2 Stammer 

 udgaa mange større og mindre Grene, der ramifiere sig- 

 nere Gange; de yderste Smaagrene bære paa deres Ender 



few subclavates are found, which are spicate at the thick 

 extremity, and have a circular, almost smooth, long shaft 

 of about same length as that of the bistellates (fig. 37); 

 also spicate, aculeate, straight, or bent, fusees, with partly, 

 rounded, partly, spicate, partly, more or less, acuminate extre- 

 mities, and measuring from 0.100 — 0.140""" in length, and 

 from 0.012— 0.016"™ in breadth (figs. 38. 39. 40). Here 

 and there, but only rarely, there are seen between the spi- 

 cules mentioned, a few quadruplets beset with small papillæ, 

 and measuring 0.080'"'" in length, and 0.060""" in breadth 

 (fig. 41). 



The spicules of the body of the polyp are very variable. 

 The most frequent forms are, spicate fusees, partly, with 

 blunt, partly, with acuminate extremities, and measuring from 

 0.120—0.200""" in length, and from 0.020—0.040""" in 

 breadth, (figs. 42. 43); also, spicate and warted subclavates, 

 measuring from 0.140 — 0.1S0 7 "'" in length, and from 0.040 — 

 0.080""" in breadth at the uppermost extremity, which 

 sometimes may be met with transversely truncated, and, in 

 that case is also beset with warts (fig. 44). 



Between the spicules mentioned, sometimes, twins, 

 sometimes, quadruplets, are frequently met with. The 

 twins are, partly, spicate, partly, aculeated, almost flat, 

 with spicate extremities and slightly constricted at the 

 middle; they are of variable length, measuring from 0.050 

 —0.080"»" in length, and from 0.010—0.020""" in breadth 

 (figs. 45. 46). The quadruplets assume, more or less, the 

 cruci-form, a few of them are rather flat, but all of them 

 are beset with larger or smaller protuberant spikes; some 

 of them are almost as broad as they are long, and measure 

 up to 0.120'"™ in diameter; others are more elongate, and 

 measure, then, 0.080"'" 1 in length, and 0.040'"" 1 in breadth 

 (figs. 47—51), but clearly distinguished cruciforms are so 

 rare, that on the entire body of a polyp only a single 

 one was observed, whose longitudinal arm measured 0.160""" 

 and the transversal arm 0.040""" (fig. 52). 



Colour. 



The entire Zoanthodem is violet, in such manner, 

 however, that the stem and the branches shade a little 

 towards yellow. The polyps are intense violet. 



Habitat. 

 Station No. 359. One specimen. 



Specific characteristics. 



The Zoanthodem measures up to 80""" in height. The 

 stem ramifies, a little way above the base, into two parts, 

 of which, the one part is somewhat thicker than the other. 

 The basal part is 70""" in circumference, and from it a 

 couple of extremely short thin branches shoot out, on 

 whose extremities there are 3 — 4 polyps. From the 2 

 stems, many larger and smaller branches proceed, which be-
