 Ender; de Takker eller Kunder, hvormed de ere forsirede,

Øverst paa Stammen ere sammensatte Stjerner og 

 Dobbeltstjerner hyppigst, enkelte ere mindre udviklede. 

 Klubber, rigt udstyrede med Papiller, tildels monstrøse i 

 Formen, ere ikke saa ganske sjeldne; men overordentlig 

 sjeldent sees ber en Firling. De sammensatte Stjerner ere 

 uregelmæssige; enhver Straale ender i en liden. tirestraalet

 Dobbeltstjernerne have ogsaa paa deres Straaleender smaa 

 Stjerner; de ere 0.088""" lange. 0.044""" brede med et 

 nogent Midtbelte. som er 0.016""" bredt. Fig. 29. Klub-

 lange og fra 0.056—0.092""" brede. Fig. 30. 31. 32. 33. 

 Enkelte Klubber ere indsnorede paa Midten: de ere 

 n.124"" lange, 0.068"""' brede foroven og 0.016""" brede 

 paa det nøgne, indsnorede Sted. Fig. 34. Firlingerne ere 

 sparsomt besatte med Takker, men disse ende ligeledes i 

 en tirestraalet Stjerne; de ere 0.008""" brede og 0.092'" 

 lange, Fig. 35. 



Paa Grenene ere Koller almindeligst; de ere dels 

 krumme, dels lige og rigt besatte med store Takker eller 

 Blade, som have snart afrundede, snart tirestraalede Ender: 

 de ere fra 0.090 -0.216""" lange og fra 0.036— 0.080" 1

 Firling, der nærmer sig Korsformen og er rigt besat med 

 Kunder og Takker, hvoraf enkelte ende i en liden Stjerne 

 og er 0.084 ' lang og 0.080 bred. Fig. 39. 



Paa Polypemes Bagkrop ere Spindler og valseformede 

 Spikler almindeligst. Spindlerne have dels tilspidsede, dels 

 afstumpede Ender, ere takkede og fra. 0.180 — 0.256""" lange 

 og fra 0.044—0.060""" brede. Fig. 40. 41. 42. De 

 valseformige Spikler synes at være noget rladtrvkte med 

 brede, afskaarne Ender og besatte med Takker: de ere

Paa Forkroppen og Tentaklerne ere Spindlerne mest 

 fremherskende; de danne ' de omtalte Ribber og indtage 

 for en stor Del TentaMernes aborale Plade. Imellem 

 Spindlerne sees tapformede Spikler og mindre, lidt rlad-

 they measure 0.096""" in length, and o.o70""" in breadth 

 [fig. 24). The spherical conglomerations measure 0.064""" 

 in diameter (fig. 25). The straight fusees have blunted 

 extremities. and the spikes, or nodules, with which they 

 are adorned, terminate. generally, in a small four-rayed star ; 

 they measure from 0.104 — 0.128™ in length. and from 

 0.032- 0.064 in breadth (figs. 26—27). 



( >n the uppermost part of the stem, complex stellates 

 and bistellates are the most frequent spicular forms, and 

 a few ut tliein are imperfectbj developed. Clavates, richly 

 adorned with papillæ, and sometimes monstrous in form, 

 are nut so ven rare. hut a quadruplet is extremely rarely 

 observed here. The complex stellates are irregular, and 

 eaeh ray terminates in a small four-rayed star; they mea- 

 sure 0.096 ' in length. and 0.060""" in breadth (fig. 28). 



The bistellates. also, have small stars 011 tlieir radial extre- 

 mities; they measure 0.088""" in length. and 0.044""" in 

 breadth, and have a bare mesial stripe measuring 0.016""" 

 in breadth (fig. 29). The clavates are richly ornamented 

 with large papillæ which terminate in four-rayed stars: they 

 measure trom 0.108—0.140""" in length. and from 0.056 

 0.092""" in breadth (figs. 30. 31. 32. 33 1. A few clav- 

 ates are constricted at the middle; these measure 0.124""" 

 in length, 0.068""" in breadth ahove, and 0.016""" in 

 breadth at the bare constricted part (rig. 34). The 

 quadruplets are sparingly beset with spikes, but these also 

 terminate in a four-rayed star; they measure 0.088""" in 

 breadth. and 0.092""" in length (fig. 35). 



( hi the branches, subclavates are the most frequent 

 spicular form ; they are sometimes curved. sonietinies straight, 

 and are richly beset with large spikes or leaves which. 

 sometimes, have rounded, sometimes four-rayed extremities; 

 they measure from 0.090 — 0.216""" in length. and from 



0.036—0.080 ' in breadth above (figs. 36. 37. 38). A 



quadruplet is seen. extremely rarely, which approaches in 

 form to the cruciform, and is richly beset with nodules 

 and spikes, of which some terminate in a small star: it 

 measures 0.084""" in length. and 0.080""" in breadth 

 (tig. 39). 



On the posterior body of the polyps. fusees and 

 cylindric spicules are the most common forms. The fusees 

 have. partly acuminated. partly, blunted extremities, and 

 are spicate: they measure from 0.1 So — 0.256""" in length, 

 and from 0.044—0.060""" in breadth (figs. 40. 41. 42 ). 

 'I he cylindric spicules appear to be somewhat tlattened, 

 have broad truncate extremities. and are beset with spikes; 

 they measure Ironi 0.120 — 0.128""" in length, aud from 

 0.048 o.iMin i,, breadth (rig. 43. 44). Besides these, 

 an occasional claviform spicate spicule is seen, which 

 measures 0.104""" in length. and from 0.020 — 0.040""" in 

 breadth (fig. 45). 



On the anterior body and the tentacles, fusees are 

 the must predominant forms; they form the rihs spoken 

 of, and occupy, in a great measure. the aboral surfacé of 

 the tentacles. Between the fusees, coniform spicules are 

 observed and. also. small, somewhat tlattened. irregular,
