lange, saa det er vanskeligt at bestemme, hvad der er 

 Længdestok, og hvad der er Tverstok. Firlingerne ere 

 omtrent 0.040'"'" saavel i Længde som Bredde, Fig. 12. 

 13. 14; imellem disse sees enkelte, takkede Do bbeltkugler, 

 0.060""" lange, 0.028""" brede i Enderne, Fig. 15. 16, dels 

 takkede Spindler, Fig. 17. 



Polypkroppens Spikier ere stillede i 8 Dobbeltrækker, 

 saaledes at i enhver Eække staa de paaskraa imod hver- 

 andre, Tab. III, Fig. 3. Den hyppigste Form, hvorunder 

 Spiklerne optræde her, er den takkede Spindel med til- 

 spidsede Ender, fra 0.200—0.280'"'" lang og fra 0.030— 

 0.040""" bred paa Midten, Tab. II, Fig. 51; imellem 

 Spindlerne sees ofte stærkt tornede Køller, snart lige, 

 snart krumme, 0.3(H)""" lange og 0.060""" brede i den tykke 

 Ende, Tab. II, Fig. 52. 53. Kun enkeltvis træffes paa 

 en korsformet Firling, hvis Længdestok er 0.080""" og 

 Tverstok 0.120""", Fig. 54, ligesom der hist og her fmdes 

 enkelte smaa, takkede Spindler med dels spidse, dels stumpe 

 Ender, 0.120""" lange, 0.020""" brede paa Midten. 



Hvor Polypkroppen gaar over i Stilken (Smaagren) 

 ophøre de tætte Spikelrækker ; Spiklerne ligge der mere 

 spredte og have de for Smaagrenene beskrevne Former, 

 Tab. III. Fig. 3. 



Generationsorganerne udvikles som sædvanligt i 

 næsten runde, stilkede Kapsler i den bagre Del af Mave- 

 hulheden. Kjønnene ere adskilte. 



Farven. 



Bleggul ; i levende Live spillende lidt i det Røde med 

 en brunlig Basal. 



Findested. 



Station 315. Et mindre Exemplar. 

 — 370. Et stort Exemplar. 



Artskarakter. 



Zoanthodemet indtil 120""" høit. Stammen 60'"'" i 

 Omkreds ved Grunden, furet paalangs og forgrenet 20 mm 

 fra G-runden og indtil Toppen. Basaldelen læderagtig, 

 ikke synderlig udvidet. Grenene nøgne, mangedelte. De 

 yderste Smaagrene bære 3 — 5 Polyper. Stammen, Grenene, 

 Smaagrenene og Stilkene (den yderste Forgrening) ere 

 forsynede med Kalkspikler i forskjellige Former. Polyperne 

 langstrakte, cylindriske med en temmelig lang Bagkrop. 



very broad, and about uniform in length, so that it is 

 difficult to decide which is the longitudinal, and which the 

 transversal arm. The quadruplets measure about 0.040""" 

 both, in length and breadth (PI. Ill, figs. 12. 13. 14). 

 Between these, a few spicate double spheres are observed, 

 measuring 0.060'"'" in length, and 0.028""" in breadth at 

 the extremities (PI. Ill, figs. 15. 16), and, partly, spicate 

 fusees (PI. Ill, fig. 17). 



The spicules of the body of the polyp are placed in 

 8 double series, in such manner, that in each series they 

 are placed diagonally opposite to each other (PI. Ill, 

 fig. 3). The most frequent form in which the spicules 

 appear, in this situation, is the spicate fusee with acumi- 

 nate extremities, and measuring from 0.200 — 0.280""" in 

 length, and from 0.030— 0.040""" in breadth at the middle 

 (PL II, fig. 51). Between the fusees, strongly aculea- 

 ted clavates are frequently observed, sometimes straight, 

 sometimes bent, and measuring 0.300'"'" in length, and 

 0.060""" in breadth at the thick extremity (PL II, figs. 

 52. 53). Only occasionally, is a cruciform quadruplet met 

 with, whose longitudinal arm measures 0.280'"'" and its 

 transversal arm 0.120'"'" (PL II, fig. 54) whilst, also, there 

 are, here and there, found, a few small spicate fusees with, 

 partly, acuminate, partly, blunt extremities, and measuring 

 0.120'"'" in length, and 0.020""" in breadth at the middle. 



"Where the body of the polyp is produced into the 

 stalk (Branchlet), the closely-set spicular series cease. 

 The spicules, there, are placed more dispersed, and they 

 posess the forms described as pertaining to the branchlets 

 (PL III, fig. 3). 



The generative organs are developed, as usual, in 

 almost spherical pedunculated capsules, in the posterior 

 part of the ventral cavity. The sexes are separated. 



Colour. 



Pale yellow ; in the live state, shading a little towards 

 red and with a brownish basal part. 



Habitat. 



Station Nr. 315. A small specimen. 

 — 370. A large specimen. 



Specific characteristics. 



The Zoanthodem measures up to 120""" in height, 

 and the stem 60""" in circumference at the base, is longitud- 

 inally grooved, ramified, commencing 20'"'" up from the 

 base and thence to the summit. The basal part is cori- 

 aceous, and not particularly dilated. The branches bare, 

 much ramified, the extreme branches carrying 3 — 5 polyps. 

 The stem, the brandies, the branchlets, and the stalks, 

 (the extreme ramifications) are furnished with calcareous
