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, nogent; 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 Koller, 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. Kollerne 

 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 fladere Spikler. 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 

 Kolleformen, 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. Kollerne 

 have noget tilfelles 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 Koller sees paa Midten et udpræget 



Kors; de- ere fra 0.11(3—0.240 lange og fra 0.024— 



0.(140 brede foroven, Fig. 77. 78. 79. 



Paa Svælgroret 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 Tinie- 

 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: tlie\ measure 0.148 in length, and 0.064 in 



breadth (rig. 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 verv broad rays, which, in some, are 

 verv 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 tii nn 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, especialbj above, 

 besel 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 (hg. 6ii). 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 pol vp. 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 alunet 

 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 soiuewhat 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 1. 



On tlie 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. vet, a little different 

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

 have the uppermost extremity almost fissured, aud in a 

 couple of these spicate subclavates a prominent cross is 

 observed in the middle. They measure from 0.116 — 



O.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
