 Tverstokken 0.100""", Fig. 29. 



Tentaklerne ere vel bepantsrede med Spikler, og hei- 

 er Spindelformen den hyppigste ; men imellem Spindlerne 

 sees baade Koller, Klubber og enkelte Firlinger. Spind- 

 lerne ere stærkt takkede og ofte forsynede med lange 

 Takker i en eller begge Ender, hvorved de faa et grenet 

 Udseende; de ere fra 0.196—0.216"»" lange og fra 0.028 

 — 0.040""" brede, Fig. 30. 31. 32. Køllerne ere som 

 Spindlerne vel forsynede med Takker, der her ere bredere 

 og mere tandede. forresten gaa Spindlerne og Køllerne 

 meget over i hverandre. Kollerne ere fra 0.176 — 0.188 



lange og fra 0.036—0.040 brede foroven, Fig. 33. 34. 



Firlingerne ere korsformede, meget smaa. mosten glatte- 

 Længdestokken er 0.044""", Tverstokken 0.036™ . Fig. 35. 

 Paa Pinnulerne ere Spiklerne meget mindre; de ere dels 

 tvinle, sparsomt takkede Spindler, fra 0.084—0.116""" lange 

 og fra 0.016 — II.02H brede. Fig. 36.37; dels smaa, tak- 

 kede, fladtrykte Klubber fra 0.080—0.116'"'" lange og fra 

 0.036—0.040""" brede foroven. Fig. 38. 39. 



Paa Svælget er 6 enkle Spikelrækker, 3 paa hver 

 Side med et bredt, spikelfrit Mellemrum. der danner Ryg- 

 og Bugpartiet, Fig. 40. Spiklerne ere temmelig flade, 

 have mest Spindelformen, ere mere eller mindre takkede 

 og stundom spaltede i den ene Ende; de ere fra 0.056 — 



0.188'"'» lange og fra 0.012—0.044 brede, Fig. 41. 42.

Farven. 

 Hele Zoanthodemet er lividt og fuldstændigt vandklart. 



Findested. 



Station 363. Nogle Exemplarer, siddende paa Rorene 

 af Onuphis conehylega. hvori Dyret levede, og i Regelen 

 paa den Del ai Roret, hvor Analenden vendte hen, uden 

 at Basaldelen dækkede for Rorets Aabning. Ved at ob- 

 servere Polypkolonien i et Glaskar viste det sig, at efter 

 nogen Tids Forlob begyndte Anneliden at krybe et Stykke 



viously spoken of; the one form is closelv bosot with papillæ, 

 and has a transversal arm of whieh the one half is small 

 and acuminated and the other broad and truncate at the 

 extremity. Tlie longitudinal arm measures 0.204""". and 

 the transversal arm 0.128""" iPl. XX. fig. 28). The other 

 form is somewhat more regular but, here, also. the trans- 

 versal arm has its one half broader than the other half. 

 The entire cross is adorned with closelv placed, foliform. 

 dentated spikes. The longitudinal arm measures 0.168""" 

 and the transversal arm 0.100 (Pl. XX. fig. 29). 



The tentacles are w ell sheathed with spicules and. 

 hore. the fusiform is the most frequent spicular form, but 

 between the fusees, both subclavates and clavates are soen. 

 and also a few quadruplets. The fusees are strongly spi- 

 cate and, often, are furnished with long spikes in one or 

 both of the extremities, which imparts to thorn a rainous 

 appearance; they measure from 0.196 — 0.216""" in length, 

 and from 0.028— 0.O40""» in breadth (Pl. XX, figs. 30. 

 31. 32). The subclavates are. like the fusees. vell supplied 

 with spikes which are. here, broader and moro dentated ; 

 the fusees and subclavates pass. otherwise, verv mueh into 

 eacn other. The subclavates measure from 0.176 — 0.188'"" 1 

 in length, and from 0.036—0.040""" in breadth above 

 (Pl. XX. figs. 33. 34). The quadruplets are cruciform, 

 very small, and almost smooth; the longitudinal arm mea- 

 sures 0.044""". and the transversal arm 0.036""" (Pl. XX. 

 tig. 35). On the pinnules the spicules are mueh smaller. 

 they are, partly, thin, sparingly-spicate, fusees, measuring 



tVom 0.084^0.116 in length. and from 0.016—0.020»»» 



in breadth (Pl. XX. figs. 36. 37) and partly, small, spicate, 

 Hattened clavates measuring trom 0.080—0.116""" in length. 



and from 0.036— 0.U40 in breadth above (Pl. XX. figs. 



38. 39). 



On the] gullet, there are 6 single spicular series. 3 

 on each side. with a broad intermediate space devoid of 

 spicules, which forms the dorsal aud ventral part (Pl. XX, 

 fig. 40). The spicules are pretty Hat and, generally, are 

 of fusiform; they are more or loss spicate, and are occa- 

 sionallv fissured in the one extremity : they measure from 

 0.056—0.188""" in length. and from 0.012—0.044""" in 

 breadth (Pl. XX. figs. 41. 42. 43. 44). 



Colour. 



The entire Zoanthodem is white and completely 

 pellucid. 



Habitat. 



Station No. 363. A few specimens seated on the 

 tubes of Onuphis conehylega, in which the animal lived, 

 and, in general, on that part of the tube where the anal 

 extremity pointed, without the aperture of the tube being 

 however obstructed by the basal part. On observing the 

 polyp-colony in a glass vessol. it appeared, that on the
