Spiklerne i Coenenchymet optræde i Form af Spindler, 

 Klubber og Firlinger. Spindlerne ore de hyppigste, men 

 variere stærkt i Formen, idet nogle nærme sig Dobbeltstjer- 

 nerne, ere 0.140""" lanse, 0.060""" brede mod Enderne og 

 have et nøgent Midtparti, 0.012™" bredt, Fig. 7, andre 

 nærme sig de sammensatte Stjerner, have en Længde at' 

 0.196""" og en Bredde af 0.060""", Fig. 8. men de Heste 

 have dog den lige Spindellbrm, ere niere eller mindre besatte 

 med Takkel-, og fra 0.104 0.160""" lanse os fra 0.028— 

 0.044™" brede. Fig. 9. 10. 11. Firlingerne ere meget 

 sjeldnere og have Korsform en ; enkelte ere næsten glatte, 

 0.064"'"' lange, 0.056""" brede. Fig. 12, andre ere rigt be- 

 sitte med Papiller og 0.148""" lange med en 0.096""" lang 

 Tverstok, Fig. 13. Klubberne ere sjeldnest og besatte med 

 l>lade, der ere takkede i Randen; de ere 0.148""" lange, 

 0.072""» brede foroven, Fig. 14. 



Paa Basaldelen ligge .Spiklerne tæt paa hverandre, 

 men danne neppe mange Las, da den er halv gjennemsigtig. 

 Dobbeltstjerner ere almindeligst, sjeldnere Køller og Klubber 

 og yderst sjeldent en Firling. Dobbeltstjernerne have 'brede 

 Straaler med som oftest takkede Ender og et nøgent Midt- 

 belte, men mange af dem have Straaler af ulige Længde 

 med stjerneformede Ender: de tørste Former ere fra 0.080 

 —0.092""» lange og fra 0.048—0.052""" brede i Enderne 



med et 0.020 bredt Midtbelte, Fig. 15. 16; de sidste 



ere fra 0.112—0.128""" lanse og fra 0.068—0.076""" brede 

 Midtbeltet er 0.028"" bredt, Fig. 17. 18. 19. Klubberne 

 ere mere eller mindre besatte med Blade, der have takkede 

 Hande, ere fra 0.100- 0.120™" lanse os fr» 0.060—0.076™" 

 brede toroven, Fig. 20. 21. Køllerne ere almindeligere end 

 Klubberne; ogsaa de ere forsynede med Blade, der ere 

 meget brede, sidde næsten krandsformigt paa Køllen og 

 have tandede Bande; de ere fra 0.124 — 0.176""" lange og 

 fra 0.052—0.064""" brede opad, Fig. 22. 23. 24. Firlin- 

 gerne have Timeglasform, ere prydede med Papiller og 

 0.068™" lange, 0.060""" brede i Enderne os 0.024™" brede 

 paa Midten, Fig. 25. 



Paa Cellen ligge Spiklerne tæt paa hverandre i de 

 8 Kibber; her ere Spindler, Klubber og Køller hyppigst, 

 sjeldnere Firlinger. Spindlerne ere lige med dels af- 

 stumpede, dels tilspidsede Ender og forsynede enten med 

 Blade eller mindre Takker; de ere fra 0.132— 0.224""" lange 

 og fra 0.028—6.044"™ brede, Fig. 26. 27. 28. 29. Klub- 

 berne ere temmelig forskjellige; enkelte nærme sig Dobbelt- 

 stjernen, andre Spindelen, samtlige ere takkede og fra 



ciiiæ. Between these cells, isolated, piriform unieellular 

 mucous glands are observed, with their slunt excretory 

 ducts opening into the gullét-cavity. 



The spicules of the sarcosoma appear in the tonn of 

 fusees. clavates, and quadruplets. The fusees are most 

 frequent, and they vary greatly in their form; surne 

 approach in form to the bistellate, and measure O.140""" 

 in length, and 0.060""" in breadth at the extremities, with 

 a bare mesial part measuring 0.012""" in breadth (fig. 7); 

 whilst others approach in form to the complex stellates, 

 and measure 0.196""" in length, and 0.060'"'" in breadth 

 (fig. 8); but must of them have, Innvever, the straight 

 fusiform aud are mure or less beset with spikes; 

 they measure from 0. 104 — 0.160""" in length, and from 

 0.028—0.044'"'" in breadth (fig. 9. 10. 11). The quadrup- 

 lets are mueh more rare, and have the cruciform; a few 

 of these are almust smooth, and measure 064""" in length, 

 and 0.056""" in breadth (fig. 12); others, of them, are richly 

 beset with papillæ, and measure 0.148""" in length, and 

 have a transversal arm measuring 0.096™" in length (fig. 13). 

 The clavates are the rarest spicular form and they are beset 

 with leaves which are spicate in the margin; they measure 

 0.148™" in length, and 0,072""" in breadth above (fig. 14). 



On the basal part, the spicules lie close upon eaeh 

 utber but can scarcely form many layers, as it is semi- 

 transparent. Bistellates are the most frequent spicular funn, 

 mure rarely du subclavates and clavates appear, and still 

 more rarely does a quadruplet appear. The bistellates have 

 broad rays, and, usually, have spicate extremities and a 

 bare mesial part, but many of them have rays of unequal 

 length, with stellifurm extremities; the first named funns 

 measure, from 0.080—0.092™" in length, and from 0.048— 

 0.052™" in breadth at the extremities, and their mesial part 

 measures 0.020™" in breadth (figs. 15. 16); the lastnamed 

 measure, from 0.112—0.128™" in length, and trom 0.068- - 

 0.076'"'" in breadth, the mesial part measuring 0.028""" in 

 breadth (figs. 17. 18. 19). The clavates are more or less 

 beset with leaves, having spicate margins, and measure from 

 0.100—0.120™" in length, and from 0.060—0.076™" in 

 breadth above (riss. 20. 21). The subclavates are met with 

 more frequently than the clavates, and they, also, are fur- 

 nished with leaves, which are very broad and are placed 

 almost in wreath-form on the bulb, furnished alsu with 

 dentated margins; they measure from 0.124 — 0.176'"'" in 

 length, and from 0.052—0.064""" in breadth above (fig. 22. 

 23. 24). The quadruplets have the sand-glass form, and are 

 adorned with papillæ; they measure 0.068'"'" in length, 



0.060 ' in breadth at the extremities, and 0.024™" in 



breadth at the middle (rig. 25). 



Un the cell, the spicules lie close upon each other in 

 the 8 ribs. In tliis situation, fusees, clavates, and subclavates, 

 are the most frequent spicular funns; quadruplets are more 

 rare. The fusees are" straight, and have, partly blunted, 

 partly acuminated extremities, and they are furnished, either 

 with leaves or small spikes; they measure from 0.132 — 

 ,1224'"'" in length, and from 0.028—0.044""" in breadth 

 (fig. 26. 27. 28. 29). The clavates are rather various; a
