naar Dyrene ere udstrakte. Kjønsorganerne tindes dels i 

 selve Kropshulheden, dels i dennes Porlængelser ned i 

 Grenen. Hos Hunnen fandtes i Regelen 3 — 5 mere eller 

 mindre udviklede Embryoner i det udvidede Svælg. 



Stammen, Grenene, Polypkroppen og den nederste 

 Halvdel af Tentaklerne er farvet svag brunrød, imedens 

 den øverste Halvdel og Pinnulerne ere mørk kastaniebrune. 



Paa Basaldelen ligge Spiklerne temmelig kompakte 

 paa hverandre og fremtræde hyppigst under Form af 

 Dobbeltstjerner, som dog variere adskilligt, saaledes at 

 enkelte nærme sig de mere sammensatte Stjerner: de ere

 Enderue: det nøghe Midtparti er fra 0.020 -0.028""" bredt, 

 Fig 8 — 11. Iblandt Dobbeltstjernerne sees en og anden 

 Spikel, der nærmest maa henføres til dem. men som af- 

 viger ved. at der fra den ene, Ende udgaar en Mængde 

 bladformede Straaler, som ere mere eller mindre takkede; 

 disse Spilder ere fra 0.116 — 0.152""" lange og fra 0.000 — 

 0.096""" hiede i den tykke, bladede Ende, imedens det 

 nøgne Midtparti er fra 0.020—0.024""" bredt, Fig. 12. 13. 

 Øverst paa Stammen og paa Grenene ligge Spiklerne mere 

 spredte; lar tindes vel Dobbeltstjerner, som ere fra 0.124

 næsten spindelformede. takkede Spilder med afstumpede, 

 tildels takkede Ender, som ere 0.108""" lange og 0.052""

Paa Polyperne ere Koller og Klubber de almindelig-

 eller mindre takkede; de ere fra 0.214 — 0.260""" lauge og 

 fra 0.080—0.084""" brede i den tykke Ende. Fig. 21—24. 

 Klubberne ere paa den øverste, tykke Del besatte med 

 Blade, der ere takkede; de ere fra 0.176—0.224""" lange 

 og fra 0.068— 0.107""" brede i den tykke Ende, Fig. 25—29. 

 Imellem de nævnte Spilder sees Spindler, dels krumme,

 eller afstumpede Ender; de ere fra 0.200—0.220""" lange 

 og fra 0.036- 0.053""" brede omtrent paa Midten. Fig.

visible when the animals are extended. The genital organs 

 are situated, partly in the body cavity itself, and partly 

 in its prolongations down into the branch. In the female 

 «ere found, usually. 3 — 5, more or less developecl embryons. 



The stem. the branches, the polyp-body, and the Iowest 

 half-part of the tentacles. are coloured pale brown-red, 

 whilst the upper half-part. and the pinnules are dark chest- 

 nut-brown. 



In the basal part, the spicules are situated rather 

 compactly upon each other, and most frequently appear 

 in the form of bistellates, which, however, vary consider- 

 ably, so that a few approach to the more complex stei- 

 ktes. They measure from 0.092 — 0.140""" in length, and 

 from 0.060—0.080""" in breadth at the extremities; the 

 bare mesial part measuring from 0.u2o — ((.028""" in breadth 

 (Pl. XIII. figs. 8 — 11). Amongst the bistellates. an occa- 

 sional spicule is observed, that must. in essential features, 

 be classed along with them, although it is different, in 

 so far, that from the one extremity a multitude of more 

 or less spicate foliaceous ravs proceed. These spicules 

 measure from 0.116—0.152""" in length, and from 0.060 

 — 0.096""" in breadth at the thick foliate extremity, whilst 

 the bare mesial part measures from 0.020 — 0.024""" in 

 breadth (Pl. XIII, figs. 12. 13). In the superior part of 

 the stem. and on the branches. the spicules are situated 

 more scatteredly. In this situation were observed, it is true. 

 bistellates. measuring from 0.124—0.132""" in length. from 

 0.072 — 0.084""" in breadth at the extremities. and the mesial 

 part measuring 0.024—0.02»""" in breadth (Pl. XTII. 

 figs. 14 — 16) ; I mt far more frequently than them, plainer, 

 almost fusiform, spicate spicules, with blunted, partly spicate, 

 extremities were observed ; these measured (.(.108'"'" in length, 



and 0.052 in breadth (Pl XIII, figs. 17. 18) and between 



these are found. not so very raivlv. small spicules which 

 are. sometimes, divided at the one extremity: these last meas- 

 ure 0.092""" in length. and 0.044""" in breadth (Pl. XIII, 

 fig. 19), sometimes they have spicate extremities and a 

 bare mesial point, and thus approach the bistellate form: 

 these measure 0.056""" in length. and 0.032""" in breadth 

 at the extremities. and have a bare mesial stripe O.012""" 

 broad (Pl. XIII. fig. 20). 



On the polyps, subclavates and clavates are the most 

 frequent spicular forms. The subclavates are partly straight, 

 partly somewhat curved, and more or less spicate. They 

 measure from 0.214—0.260""" in length. and from 0.080— 

 0.084""" in breadth at the thick extremity (Pl. XIII. 

 figs. 21- 24). The clavates are. on the superior thick 

 part. bcset with leaves which are spicate. and they measure 



from 0.176—0.224 in length, and from 0.068— 0.107""" 



in breadth at the thick extremity (Pl. XIII, figs. 25—29). 

 Between the aforenamed spicules. fusees are observed, partly 

 curved, partly straight, having larger or smaller -pikes, aud 

 with acuminate or truncate extremities: they measure from 



0.200—0.220 in length. and from 0.036—0.053""" in 



breadth at about the middle (Pl. XIII, figs. 30—34).
