Artskarakter. 



Zoanthoclemet indtil 35'""'" høit. Stammen rand, furet 

 . paalangs, 20 — 25'"'" i Omfang ved Granden, aftagende lidt 

 i Tykkelse opad. Basaldelen tynd, membranagtigt udvidet. 

 Stammen lige fra Granden og til Toppen besat med korte, 

 tykke Grene, der i Regelen dele sig nogle Millimeter fra 

 Udspringet i 3 — 4 mindre Grene, som atter dele sig i 

 mange Smaagrene, der hver bærer 6 — 7 Polyper. Disse 

 ere kolbeformige, 4'"™ lange. Polypkroppen 2,5""" lang, rigt 

 forsynet med Spikier, som paa Forkroppen ordne sig i. 

 Rækker, der ophøre ved Tentaklernes Grund. Tentaklerne 

 næsten ligesaa lange som Kroppen, uden Spikier. Spiklerne 

 paa Basaldelen og den nederste Del af Stammen optræde 

 væsentlig under Form af takkede, vortede, krumme og 

 lige Spindler, samt meget sammensatte Stjerner; imellem 

 dem enkelte Dobbeltstjerner, Køller og Firlinger. Paa 

 Polypkroppen er Spinclelform hyppigst. Farven stærk 

 straagul.

Zoanthoclemet indtil 28 rara høit. Stammen rund, furet 

 paalangs, dens Omkreds ved Granden 20""". Basaldelen tyk, 

 fast, haard, noget udvidet. Stammen aftager lidt i Tyk- 

 kelse op imod Toppen, hvor den deler sig i to Grene, der 

 hver forgrene sig i flere Smaagrene, som bærer Grupper af 

 Polyper, 6 — 7 i hver. Kun nogle Millimeter ovenfor 

 Basaldelen og indtil Toppen er Stammen rundtom forsynet 

 med Grene, der staa temmelig langt fra hverandre, ere 

 korte, tykke, og hvoraf flere lige ved Udspringet dele sig 

 i 2 mindre Grene, som igjen afgive mange Smaagrene, der 

 hver bære 6 — 7 Polyper, medens andre i et Par Millime- 

 ters Aistand fra Stammen dele sig i mange Smaagrene, 

 som hver bærer omtrent et lignende Anta! Polyper. Smaa- 

 grenene ere meget korte, temmelig sammentrængte og 

 skjules ganske af de tæt grupperede Polyper, Fig. 82. 83.

Specific characteristics. 



The Zoanthodem measures up to 35""" in height. 

 The stem cylindrical, longitudinally furrowed. 20— 25"™ in 

 circumference at the base, diminishing a little in thickness 

 upwards. The basal part thin, and membranaceously dilated. 

 The stem, right from the base and to its summit, beset 

 with short, thick branches, which, as a rule, ramify, a few 

 millimetres beyond their root, into 3 — 4 smaller branches, 

 which, again, ramify into many branchlets, each of which 

 carries 6—7 polyps. These latter are clavate-formed and 

 measure 4'"'" in length. The body of the polyp measures 

 2,5'"'" in length, and is richly furnished with spicules 

 which, upon the anterior body, arrange themselves in series 

 that terminate at the root of the tentacles. The tentacles 

 are almost as long as the body, and are devoid of spicules. 

 The spicules in the basal part, and the lowest part of the 

 stem, appear, principally, in the form of spicate, warted, bent 

 and straight, fusees, also, as very complex stellates. Between 

 them occasional bistellates, subclavates and quadruplets are 

 visible. On the body of the polyp the fusi-form is most 

 frequent. Colour, strong straw-yellow. 



Duva cinerea. n. sp. 



PI. V, figs. 82—93. PL VI. figs. 1—29. 



The Zoanthodem measures up to 28""" in height. 

 The stem is cylindrical, longitudinally grooved, and mea- 

 sures, at the base, 20""" in circumference. The basal part 

 is thick, firm, hard, and somewhat dilated. The stem di- 

 minishes a little in thickness up towards the summit, at 

 which point it ramifies into two branches, each of which 

 again ramify into several branchlets carrying groups of 

 polyps, 6 — 7 polyps in each group. From only a few 

 millimetres above the basal part, and up to the summit, 

 the stem is, round about it, furnished with branches, which 

 are placed pretty far apart from each other, and are short 

 and thick; several of these ramify, right at the root, 

 into 2 smaller branches, which, again, ramify into numerous 

 branchlets, each of which carries 6 — 7 polyps; whilst others, 

 at a couple of millimetres distance from their root, ramify 

 into many branchlets, each of which carries about a similar 

 number of polyps. The branchlets are very short, rather
