Artskarakter. 



Zoanthodemet 70 — 80 mm høit. Basaldelen 25""" i Om- 

 kreds ; Stammen forøvrigt temmelig smal, stærkt riflet efter 

 Længden, og dens øverste to Trediedele ere rundtom for- 

 synede med Grene, den nederste Trediedel uden saadanne ; 

 men her udspringe enkelte Polyper direkte fra Stammen. 

 Grenene noget spredte, i Regelen delte; saavel paa Smaa- 

 grenene som paa de udelte Grene sidde Polyperne i 

 Grupper. Stammen, Grenene og Smaagrenene overordent- 

 lig rig paa Kalkspikler. Polyperne lange, cylindriske, 

 meget rige paa Spilder og forsynede med 8 fremspringende 

 Ribber. Paa Forkroppen staa Spiklerne næsten opret i 

 8 tætte Dobbeltrækker og dannes væsentlig af takkede, 

 dels krumme,, dels lige Spindler; paa Bagkroppen ligge 

 Spiklerne paatvers og have Form af vortedannede Valser, 

 Dobbeltstjerner, Firlinger og takkede Spindler. Tentak- 

 lerne og Pinnulerne fuldstændigt bepantsrede med forskjel- 

 ligt formede Spilder. Svælget forsynet med 8 tætte 

 Dobbeltrækker, væsentligt takkede, Spindler. Farven gul, 

 spillende lidt i elet Brune.

Zoanthodemet varierer meget baade med Hensyn til 

 Form og Størrelse efter de forskjellige Lokaliteter. Det 

 største Exemplar er 110""" høit, og paa dette danner den 

 membranøse Basaldel to cylindriske Rør, hvoraf det ene 

 er 40" m langt og 35 mm tykt, det andet er 30 m ™ langt og 

 28""" tykt, begge ere fyldte med en graasort Lermasse,

extremities, and measure 0.220""" in length, and 0.028 ram 

 in breadth ; also subclavates of about the same length ; and, 

 strongly spicate, somewhat flattened, staves, with blunted, 

 partly ramous, extremities, and measuring 0.120'"'" in 

 length, and 0.140'"'" in breadth at the middle (fig. 41). 



Colour. 



The colour is yellow, shading somewhat towards 

 brown. The basal part is brown. 



Habitat. 



Stations, No. 192. 200. Three specimens. 



Specific characteristics. 



The Zoanthodem measures 70 — 80""" in height. The 

 basal part is 25""" in circumference. The stem, otherwise, 

 is pretty narrow, strongly grooved longitudinally, and 

 its uppermost two-third parts is, round about it, furnished 

 with branches; the lowest third part has none but, in 

 this situation, a few polyps spring direct from the stem. 

 The branches are somewhat dispersed and, generally, ram- 

 ous. Both, upon the branchlets and upon the non-ramous 

 branches, the polyps are placed in groups. The stem, 

 the branches, and the branchlets, are extremely rich in 

 calcareous spicules. The polyps are long, and cylindrical, 

 very rich in spicules, and are furnished with 8 projecting ribs. 

 On the anterior body, the spicules are placed, almost 

 erect, in 8 double series, and are formed, principally, of 

 spicate, partly bent, partly straight, fusees. On the pos- 

 terior body, the spicules are placed transversally, and have 

 the form of protuberated rollers, bi-stellates, quadruplets, 

 and spicate fusees. The tentacles and the pinnules are 

 completely sheathed, with spicules of various forms. The 

 gullet is furnished with 8 closely-set double series of, prin- 

 cipally, spicate fusées. The colour is yellow, shading 

 a little towards brown.

Pl. IX, fig. 1—40. 



The Zoanthodem varies much, both with respect 

 to its form and its size, according to the different local- 

 ities. The largest specimen measures, 110 mra in height 

 and, in it, the membranaceous basal portion forms two 

 cylindrical tubes, of which, one measures 40'" m in length, 

 and 35""" thick; and the other measures, 30"™ in length, 

 and 28""" thick; both are occupied by a greyish-black, 

 aluminous mass (fig. 1). From the middle of each of these
