Paa Basaldélen ligge Spiklerne tæt paa hverandre, 

 og her åndes de sammensatte Stjerner. Dobbeltstjerner og 

 Klubber at være stærkest repræsenterede, sjeldnere Spind- 

 ler og Firlinger. De sammensatte Stjerner have brede 

 Straaler med takkede Ender, ere 0.132"™ lange og 0.064 mm 

 brede, Tab. XVII, Fig. 56. Dobbeltstjernerne ere mere 

 eller mindre udviklede, enkelte ere langstrakte og lidt 

 krummede, men alle have et nøgent Midtbelte; de ere 

 fra 0.076—0.100»"" lange og fra 0.032— 0.064™» brede, med 

 et Midtbelte, der er fra 0.012— 0.020"™ bredt, Tab. XVII, 

 Fig. 57. 58. 59. 60. Klubberne ere bredbladede, takkede, 

 og Skaftet undertiden spaltet; de ere fra 0.092—0.120""" 

 lange og fra 0.052—0.120»"" brede foroven, Tab. XVIII, 

 Fig. 4. 5. 6. Firlingerne antage mest Korsformen, enkelte 

 have Form af en firearmet Stjerne, stærkt ornamenteret, 

 og ere omtrent lige lange som brede, 0.088™'", Tab'. 

 XVIII, Fig. 7. 8; de øvrige ere fra 0.060— 0.092""" lange 

 med en Tverstok fra 0.060— 0.076'""' bred, Fig. 9. 10. 11. 12. 

 Spindlerne have brede, temmelig langt fra hverandre staaende 

 Takker og nærme sig noget de mindre udviklede, sammen- 

 satte Stjerner; de ere 0.096"'"' lange og 0.044""" brede 

 paa Midten; Enderne ere tilspidsede, Fig. 13. 



Paa Stammen er bladede Spindler og Dobbeltstjerner 

 almindeligst, noget sjeldnere ere Klubber og Spindler, næsten 

 glatte, stundom gaffelformigt delte i Enderne; men meget 

 sjeldent er her Firlinger. De bladede Spindler nærme 

 sig meget de sammensatte Stjerner, som findes paa Basal- 

 délen, men ere dog forskjellige fra dem ved deres tilspid- 

 sede Ender. Bladene have tandede Rande; de ere 0.140'"»' 

 lange og 0.060"'"' brede paa Midten, Fig. 14. Dobbelt- 

 stjernerne ere meget særegne, de have intet nøgent Midt- 

 parti, og dette er som oftest besat med smaa Papiller, der 

 tildels have en Stjerneform ; stundom ere deres Straaler 

 saa rigt ornamenterede, at de antage en smuk Rosetform; 

 de ere fra 0.084—0.100""" lange og fra 0.044—0.068»"" 

 brede i Enderne; Midtpartiet er omkring 0.032""" bredt, 

 Fig. 15. 16. 17. 18. Klubberne ere mere eller mindre 

 udviklede, nogle ere besatte med brede, i Randen tandede 

 Blade og ligne Blomsterbuketter, andre ere sparsomt be- 

 satte, dels med Blade, dels med Takker; de ere fra 0.088 

 —0.132""" lange og fra 0.032—0.064""» brede foroven, 

 Fig. 19. 20. 21. 22. 23. De næsten glatte Spindler ere 

 0.108""" lange og 0.032'""' brede paa Midten, Fig. 24, og 

 de gaffelformige, som ere tæt besatte med temmelig lange 

 Papiller, ' ere 0.156'"'" lange og 0.040""" brede paa Midten, 

 Fig. 25. Firlingen er i Korsform, besat med Papiller, hai-

posterior part which forms itself, thus, into the cell, (Pl. 



XVII, Fig. 55, &). 



In the basal part, the spicules are placed close upon 

 each other and, here, the complex steiktes, bistellates 

 and clavates, are found to be the forms most numerously 

 represented, the fusees and quadruplets being less 

 frequent. The complex stellates have broad rays with 

 spicate extremities, and they measure 0.132'"'" in length, 

 and 0.064'"'» in breadth, (Pl. XVII, fig. 56). The bistel- 

 lates are more or less developed; a few are elongate and 

 slightly curved, but all of them have a bare mesial stripe ; 

 they measure from 0.076—0.100""" in length, and from 

 0.032—0.064""" in breadth, with the mesial stripe meas- 

 uring from 0.012—0.020""" in breadth, (Pl. XVII, fig. 

 57. 58. 59. 60). The clavates are broad-leafed, spicate, 

 and their shaft is, occasionally, fissured ; they measure from 

 0.092—0.120""" in length, and from 0.052—0.120'"'" in 

 breadth above (Pl. XVIII, figs. 4. 5. 6). The quadrup- 

 lets assume, principally, the cruciform; a few have the 

 form of a four-rayed star strongly ornamented, these are 

 about as long as they are broad and measure 0.088'"'" 

 (Pl. XVIII, figs. 7. 8). The others measure from 0.060 

 —0.092"™ in length, and have a transversal arm which 

 measures, from 0.060— 0.076"™ (Pl. XVIII, figs. 9. 10. 11. 

 12). The fusees have broad spikes placed pretty far 

 apart from each other, and approach in form, somewhat, 

 to the imperfectly developed complex stellates; they meas- 

 ure 0.096""" in length, and 0.044"™ in breadth at themidclle, 

 the extremities are acuminated (PL XVIII, fig. 13), 



In the stem, foliaceous fusees and bistellates are the 

 most frequent forms; somewhat more rarely are clavates 

 and fusees met with, which are almost smooth, and occasionally 

 bifurcated in the extremities; very rarely are quadruplets 

 met with here. The foliaceous fusees approach greatly in 

 form to the complex stellates found in the basal part but, 

 yet, are different from them in regard to the acuminated 

 extremities, and the leaves have dentatecl margins ; they measure 

 0.140"™ in length, and 0.060"™ in breadth at the middle (PL 



XVIII, fig. 14). The bi-stellates are very peculiar ; they have 

 no bare mesial part, it being, most frequently, beset with 

 small papilla?, that sometimes have a stelliform, and their 

 rays are, occasionally, so ornamented that they assume a 

 beautiful rosetti-form ; they measure from 0.084-0.100'""" 

 in length, and from 0.044—0.068""" in breadth at the 

 extremities, the mesial part measuring about 0.032""" in 

 breadth (PL XVIII, figs. 15. 16. 17. 18). The clavates 

 are more or less developed; a few are beset with broad 

 leaves dentated in the margins, 'and resemble bouquets of 

 flowers; others are sparingly beset, sometimes with leaves, 

 sometimes, with spikes; they measure from 0.088 — 0.132""" 

 in length, and from 0.032 — 0.064""" in breadth above 

 (PL XVIII, figs. 19. 20. 21. 22. 23). The nearly smooth 

 fusees measure 0.108'""' in length, and 0.032'""' in breadth 

 at the middle (PL XVIII, fig. 24), and the bifurcated 

 ones are closely beset with pretty long papillæ; they 

 measure 0.156""" in length, and 0.040"™ in breadth at the 

 middle (PL XVIII, fig. 25). The quadruplets are cruci-
