 de almindeligste Spikellormer. De sammensatte Stjerner 

 have brede, blade"de Straaler ull- ere fra 0.080 — 0.208""° 



lange og fra 0.060— 0.096 brede, Fig. 44—4(1. Rosetterne

Imelleni disse Spilder, men temmelig sjeldent, sees Klub-

 andre ere bladede med et næsten 'glat Skaft ; de ere fra 



0.104—0.224""" lange og fra 0.060—0.112 brede for- 



oven, Fig. 51. 52. Dobbeltstjemerne ere her yderst sjeldne, 

 0.120""" lange, 0.068""" brede mod Enderne og med et nøgent 

 Midtbelte, der er 0.016""" bredt, Fig. 53; men sjeldnest 

 er dog en pyramideformet, takket Spikel med en bred 

 Basis. 0.148' lang. 0.100 bred ved Granden, Fig. 54. 



Paa Folypkroppen er det fornemmelig Spindel- og 

 Tapformen, der gjør sig gjældende. Spindlerne ere takkede, 

 dels lige, dels krumme, fra 0.188—0.420""" lange- og fra 



0.028—0.076 brede, Fig. 55—58; paa enkelte af disse 



Spindler sees den begyndende Korsdannelse. der dog er 

 sjelden. Tapperne ere takkede, stundom lidt krummede ; de 

 mindste ere 0.096""" lange og 0.040""" brede foroven, men 

 de største, som ere de almindeligste, ere 0.220'"'" lange, 

 0.048""" brede foroven, hvor de ere næsten tvers afskaarne, 

 Fig. 59 — 62. Imellem disse Spilder sees krumme, takkede 

 og vortede Koller, tildels med et tyndt. tilspidset Haand- 

 greb; de ere fra 0.084—0.132""" lange og fra. 0.036— 

 0.052""" brede, Fig. 63. 64, samt enkelte, men sjeldne, tornede

Paa den nederste Halvdel af Tentaklernes aborale 

 Side tindes lignende store, takkede Spindler og Tapper 

 som de. der ere omtalte paa Kroppen, Fig. 56 — 60; men 

 dels til Siderne, dels ovenfor dem sees Rækker af 

 mindre Spilder, der ere noget fladere og have en meget 

 forskjellig Form. hvoriblandt korsformede Firlinger. Disse 

 Spilder ere takkede, tornede og variere meget i Størrelse, 



fra 0.024—0.088""" lange og fra 0.016—0.036 brede; 



de korsformede Firlinger have en Længdestok tra 0.056 —

Den norske Nordhavsexpeditiou. D. C. Danielssen: Aleyonida, 



On the branehes, the complex stellates and rosettes are 

 the most frequent spicular forms. The complex stellates 

 have broad foliaceous rays, and measure from 0.080 — 0.208'"™ 

 in length, and from 0.060—0.096""" in breadth (Pl. VIII, 

 figs. 44 — 4(*>). The rosettes are different in form from 

 those that are found on the stem. «hilst, also, they are 

 pretty dark yéllowish-brown in colour; the v measure from 



0.060—0.080 in length, and from 0.056—0.068 in 



breadth (Pl. VIII, figs. 47 — 50). Between these spicules, 

 but rather iarely, clavates are observed, of which a few 

 are nearly quite smooth, whilst others are foliaceous and 

 have an a.lmost smooth shaft; they measure from 0.104 — 



0.224 in length. and from 0.060—0.112 in breadth 



above (Pl. VIII. figs. 51. 52). The bistellates are. in this 

 situation. extremely rare. and measure 0.120""" in length, 



and 0.068 in breadth towards the extremities, and they 



have a bare mesial belt measuring 0.016""" in breadth 

 (Pl. VIII, fig. 53); but the most rare of all is. the piri- 

 form spicate spicule with a broad basis; it measures 

 0.148""" in length, and 0.100""" -in breadth at the base, 

 (Pl. VIII, fig. 54). 



On the body of the polyp, it is principally fusiform 

 and coniform spicules which are most prominent. The 

 fusees are spicate, partly straight, partly bent, and mea- 

 sure from 0.188—0.42(1 in length. and from 0.028— 



().()7(; in breadth (Pl. VIII, figs. 55—58). In a few of 



these fusees, the rudimentarv crucial-formatiou is observed, 

 but rarelj jiowever. The cones are spicate, occasionally 

 they are a little bent; the smallest measure 0.096""" in 

 length, and 0.040""" in breadth above; but the largest, 

 which also are the most frequent, measure 0.220""" in 



length. and 0.048 ' in breadth above, at which point 



they are almost transverselv truncated (Pl. VIII. figs. 

 59 — 62). Between these spicules, bent, spicate and warted 

 subclavates are seen, partly. with a thin acuminated shaft ; 

 they measure from 0.084—0.132""" in length, and from 



0.036— 0.052 in breadth, (Pl. VIII, figs. 63. 64), also. 



but rarely, a few aculeated clavates from whose uppermost 

 extremity long thick spikes proceed (Pl. VIII, fig. 65). 



On the lowest half part of the aboral side of the 

 tentacles, large spicate fusees and cones, similar to those 

 spoken of in connection with the body, are found (Pl. 

 VIII, figs. 56—60) but, partly to the sides of these. 

 partly above them, series of smaller spicules are seen, 

 which are somewhat datter, and have very variable forms, 

 amongst these being cruciform quadruplets. These spicules 

 are spicate, or aculeated, and they vary much in size, mea- 

 suring from 0.024—0.088""" in length. and from 0.016— 

 0.036""" in breadth. The cruciform quadruplets have a longi- 

 tudinal arm measuring from 0.056—0.080""" in length, 

 and a transversal arm,, measuring from 0.024 — 0.056""" 

 (Pl. VIII, figs. 66—76).'
