Paa Grenene ere Dobbeltstjernerne hyppigst, men 

 foruden dem træffes dog Klubber ofte, sjeldent sees Spindler. 

 Dobbeltstjernerne have meget brede Straaler, der paa 

 enkelte ere meget korte, næsten som Papiller, men ende i 

 en liden, firestraalet Stjerne; Midtpartiet er mere eller 

 mindre langt, nøgent; de ere fra 0.064—0.100""" lange og 

 fra 0.048—0.056""" brede i Enderne; Midtbeltet er fra 

 0.016-0.024""" bredt, Fig. 63. 64. 65. Klubberne ere, 

 især foroven, besatte med brede Takker, der ende i en 

 firestraalet Stjerne. Skaftet er kort og har et Par lignende 

 Takker; de ere 0.120'"'" lange, 0.076""" brede foroven. Fig. 

 66. Spindlerne ere særegne, have langt fra hverandre 

 staaende, brede Blade, der ogsaa ende i en liden Stjerne; 

 de ere 0.152'""' lange, 0.064""" brede, Fig. 67. 



Paa Polypkroppen er det Spindler og Køller, som 

 ere mest fremherskende. Spindlerne ere dels krumme, dels 

 lige, yderst sparsomt besatte med Takker, enkelte ere 

 næsten glatte; de ere fra 0.232 — 0.248'""' lange og fra 

 0.036 -0.052""" brede paa Midten, Fig. 68. 69. Køllerne 

 ere heller ikke meget takkede; Takkerne ere i Reglen 

 smaa, staa langt fra hverandre; de ere fra 0.156 — 0.236""" 

 lange og fra 0.044—0.052'"*" brede foroven, Fig. 70. 71. 72. 

 Imellem de nævnte Former sees hist og her mindre og 

 lidt flaclere Spilder, der have afstumpede Ender og faa 

 Takker; de ere fra 0.084—0.144'""' lange og fra 0.028— 

 0.036'"'" brede, Fig. 73. 74. 



Paa Tentaklerne er det væsentligst Spindel- og 

 Kølleformen, som gjør sig gjældende. Spindlerne ere dels 

 næsten glatte, dels takkede ; Takkerne ere smaa, staa tem- 

 melig langt fra hverandre; paa de takkede Spindler ere 

 Enderne stærkt tilspidsede; de ere fra 0.196 — 0.300""" 

 lange og fra 0.032—0.044""" brede, Fig. 75. 76. Køllerne 

 have noget tilfælles med dem paa Kroppen, men ere dog 

 lidt forskjellige fra dem; enkelte ere glatte, andre ere 

 takkede med den øverste Ende næsten spaltet, og paa et 

 Par af disse takkede Køller sees paa Midten et udpræget 

 Kors; de ere fra 0.116—0.240'""' lange og fra 0.024— 

 0.040™" brede foroven, Fig. 77. 78. 79. 



Paa Svælgrøret sees hyppigst' Firlinger og Spindler 

 forsynede med Takker. Spiklerne ere her noget fladtrykte. 

 Firlingerne ere tildels korsformede, 0.100""" lange med en 

 Tverstok, der er 0.088""", Fig. 80, dels nærme de sig Time- 

 glasformen, Fig. 81. Spindlerne ere fra 0.124 — 0.148'"'" 

 lange og fra 0.016—0.028'"'" brede, Fig. 82. 83. 



fusees have broad spikes which terminate in a four-rayed 

 star; they measure 0.148""" in length, and 0.064""" in 

 breadth (fig. 62). 



On the branches, the bistellate is the spicular form 

 most frequently met with, but, besides it, clavates are, 

 also, frequently, observed; fusees are rarely observed. 

 The bistellates have very broad rays, which, in some, are 

 very short, almost like papillæ, but terminate in a small, 

 four-rayed star ; their intermediate portion is, more or less, 

 long, and bare; they measure from 0.064—0.100'""' in length, 

 and from 0.048— 0.056""" in breadth at the extremities. 

 The intermediate stripe measures from 0.016 — 0.024""" in 

 breadth (figs. 63. 64. 65). The clavates are, especially above, 

 beset with broad spikes, which terminate in a four-rayed 

 star. The shaft is short, and has -a couple of similar spikes ; 

 they measure 0.120""" in length, and 0.076""" in breadth 

 above (fig. 66). The fusees are peculiar, and have broad 

 leaves placed far apart from each other, and which also ter- 

 minate in a small star; they measure 0.152""" in length, and 

 0.064""" in breadth (fig. 67). 



On the body of the polyp, fusees and subclavates 

 are the most predominant spicular forms. The fusees are, 

 sometimes, bent, sometimes, straight, and are extremely 

 sparingly beset with spikes, a few of them are almost 

 smooth; they measure from 0.232—0.248""" in length, and 

 from 0.036-0.052'""' in breadth at the middle (figs. 

 68. 69). Neither are the subclavates very spicate, and 

 their spikes, as a rule, are small, and placed far 

 apart from each other; they measure from 0.156 — 0.236'"'" 

 in length, and from 0.044—0.052""" in breadth above 

 (figs. 70. 71. 72). Between the forms just named, there 

 are, here and there, seen, smaller, and somewhat flatter 

 spicules, having blunted extremities and few spikes; these 

 measure from 0.084 — 0.144""" in length, and from 0.028— 

 0.036""" in breadth (figs. 73. 74). 



On the tentacles, it is, principally, the fusiform and 

 subclaviform spicular forms that are met with, as pre- 

 dominating. The fusees are, sometimes, almost smooth, 

 sometimes, spicate. The spikes are small and placed 

 pretty far apart from each other. In the spicate fusees, 

 the extremities are strongly acuminated; they measure 

 from 0.196—0.300""" in length, and from 0.032—0.044""" 

 in breadth (figs. 75. 76). The subclavates resemble, some- 

 what, those of the body, but are, yet, a little different 

 from them ; a few are smooth, others are spicate, and 

 have the uppermost extremity almost fissured, and in a 

 couple of these spicate subclavates a prominent cross is 

 observed in the middle. They measure from 0.116 — 

 0.240""" in length, and from 0.024—0.040'""' in breadth 

 above (figs. 77. 78. 79). 



On the gullet-tube, quadruplets and fusees, furnished 

 with spikes are the most frequent spicular forms observed. 

 The spicules are, here, somewhat flattened. The quadrup- 

 lets are, partly, cruciform, and measure 0.100""" in length, 

 with a transversal arm measuring 0.088""" (fig. 80); some- 

 times their form approaches to that of the sand-glass 

 (fig. 81). The fusees measure from 0.124 — 0.148'""' in
