Enderne; Midtbeltet fra 0.020—0.060 ' bredt. Fig. o. 6. 



7. 8. 9. LO. (De sidste 3 ere mindre udviklede Former), 

 [mellem Dobbeltstjernerne sees enkeltvis enten en sammen- 

 sæt Stjerne, der næsten har Form af Klubben, eller en 

 Klubbe, nærmende sig den sammensatte Stjerne; de have 

 ligeledes brede Straaler, som ere besatte med smaa Kalk- 

 korn, der stundom se ud, som om de vare strøede ud over 

 Straalerae, ligesom de tindes paa Midtpartierne; disse 

 Spilder ere 0.228""" lange. 0.132""" brede. Fig. 11. Fir- 

 lingerne have Korsform og ere besatte med spredte Blade 

 eller Papiller, hvorimellem sees de fine, runde Kalkkorn; 

 de ere 0.136 lange med en Tverstok 0.132'"'", Fig 12. 



Paa Stammen og Grenene ligge Spiklerne temmelig 

 kompakte, og er her sammensatte Stjerner almindeligsl ; 

 sjeldnere Koller. De sammensatte Stjerner ere tildels 

 lidt krumbøiede og da lidt uformelige; men forresten have 

 de alle brede Blade med takkede Rande og ere besatte med 

 yderst smaa Kalkkorn; de ere fra 0.160 — 0.216'"'" lange 



og fra 0.088—0.100 brede. Fig. 13. 14. Køllerne ere 



forsynede med brede, i Randen indskaarne Blade; enkelte 

 menne sig Spindelformeii. og alle have en større eller 

 mindre Mængde runde Kalkkorn; de ere fra 0.192 — 0.232™" 



lange og fra 0.068—0.088 hivd,.. Fig. 15. 16. Imellem 



disse Spikler sees. men ydersl sjeldent, en bred, med 

 Blade rigt udstyret Spike! i Rosetform, der ligesom er 



bestrøet med smaa. runde Kalkkorn og 0.216 lang og 



148 bred, Fig. 17. 



Paa Cellerne ere elliptiske Spindler hyppigst, meget 

 sjeldnere ere Dobbeltstjernerne og yderst sjelden en Fir- 

 ling. De elliptiske Spindler variere temmelig meget i 

 Form; enkelte nærme sig noget Kollen, andre noget sam- 

 mensatte Stjerner. I Almindelighed have de Midtbelte, 

 der er overstroet med Smaakom. ellers ere de udstyrede 

 med brede Blade. som ere takkede i Randen og ligeledes 

 kornbestroede; de ere fra 0.248 — 0.276""" lange og fra 

 0.104—0.124""" brede, Fig. 18. 19. Dobbeltstjernerne 

 have brede, delte Straaler med takkede Rande ; Midtpartiet 

 er ogsaa besat med Blade; de ere 0.132""" lange. 0.072""" 



brede i Enderne med et 0.032 bredt Midtbelte. Fig. 20. 



Firlingen er i Form af en meget rigt ornamenteret Roset, 

 overstroet med tine Kalkkorn. der nærme sig noget den 

 paa Stammen omtalte brede, med Blade prydede Spikel, 

 Fig. 17. men adskiller sig fra denne dog derved, at den 

 virkelig har 4 Afdelinger: Firlingens Karakter: den er 



0.232 lang. 0.172 bred i Enderne. paa Midten 0.120 



bred. Fig. 21. 



deposited armost everywhere. These bistellates measure 



from 0.096—0.168 in length. and from 0.044—0.146 



in breadth at the extremities. The medial stripe measures 

 from 0.020—0.060""" in breadth (fig. 5. 6. 7. 8. 9. 10). 

 iThe last 3 are imperfectly developed forms). Between 

 the bistellates there is, occasionally, observed, either a 

 complex stellate having almost the claviform, or a clavate 

 approaching in form to the complex stellate; these, 

 also, have broad rays that are beset with minute calcareous 

 grannules appearing, sometimes, as if they were strewed 

 over the rays. and grannules are likewise found on the 

 medial parts; these spicules measure 1 1.228""" in length. 

 and 0.132""" in breadth (fig. 11). The quadruplets have 

 the cruci-form. and are beset with scattered leaves or pa- 

 pillæ, between which the minute round calcareous grannules 



are seen; they measure 0.136 in length, and have a 



transversal arm measuring 0.132""" (fig. 12). 



On the stem and the branches, the spicules are placed 

 pretty compactly, and. here, complex stellates are the 

 most frequent spicular tonns met with. more rarely are 

 subclavates seen. The complex stellates are. sometimes, ;i 

 Little crooked, and are. then. somewhat misshapen, but 

 otherwise, they all have broad leaves having spicate mar- 

 gins, aud are besel with extremely minute calcareous gran- 

 nules; the\ measure from 0.160 — 0.216""" in length. and 

 trom 0.088—0.100 in breadth (figs. 13. 14). The sub- 

 clavates are furnished with broad leaves clentated in the 

 margins, a few approach in form to the fusiform, and all 

 of them have a greater or h'ss abundance of round cal- 

 careous grannules; they measure from 0.192- 0.232 in 



length", and from o.o6S_ 0,088""" in breadth (figs. 15. 16). 

 Between these spicules, there is seen but extremely 

 rarely — a broad spicule richly adorned with leaves, in 

 rosettiform, and which appears as if strewed over with min- 

 ute. round. calcareous grannules; it measures 0.216""" in 

 length. and 0.148""" in breadth (fig. 17). 



On the cells. elliptic fusees are the most frequent 

 spicular form. much more rarely do bistellates appear, 

 and extremely seldom is a quadruplet seen. The elliptic 

 fusees va ry pretty much in form, a few approach in form 

 to tin 1 subclavate, others. again, somewliat to the complex 

 stellate. ln general, they have medial stripes which are 

 overstrewed with minute grannules, or they are furnished 

 with broad leaves which are spicate in the margins and. 

 likewise, overstrewed with grannules; they measure trom 



d.248—0.276 in length, and from 0.104 -0.124 in 



breadth (fig. 18. 19). The bistellates have broad, ramous, 

 rays with spicate margins, and the medial part is. also. 



beset with leaves; they measure 0. 132 in length. and 



0.072 in breadth at the extremities. and have a mesial 



stripe measuring 0.032 in breadth (fig. 20). The quad- 

 ruplet has the form of a very richly ornamented rosette 

 overstrewed witTi minute. calcareous grannules, and it 

 approaches, somewhat. in form to the broad spicule adorned 

 with leaves previously spoken of as found upon the stem 

 (fig. 17). but (lifters from it. however, in. really. having 

 four divisions, the characteristic feature of the quadruplet;
