 nøgent Midtparti, der i Regelen er halvt saa bredt som 

 Enderne, Fig. 4. 5. Spindlerne ere i AlmindeHghed besatte 

 med Vorter og sum oftest lige, men forekomme ogsaa 

 mere eller mindre krumme; deres Ender ere dels tilspidsede

Paa den nederste Del at' Stammen ligge Spiklerne 

 mere spredte end paa Basaldelen, og man træffer der om- 

 trent de samme Former som paa denne; den øverste Del 

 er, som forhen omtalt, spikelfri. 



Faa Polypkroppen, der er rig paa Spilder, forekom- 

 mer Spindelformen hyppigst. Det er væsentligst takkede, 

 lige eller krumme, vortede Spindler, dels med stumpe, 

 dels med tilspidsede Ender, sum danne de før beskrevne 

 Rækker paa Forkroppen, og det er lignende Spindler, som 

 udgjør Hovedmassen af Spiklerne paa Bagkroppen, Fig. 3. 

 De ere af» forskjellig Størrelse, fra O.l (JO— 0.266""» lange og 

 fra 0.036—0.056""" brede. Fig. 21—25; og der, hvor 

 Spikelrækken afsluttes ved Tentakelgrunden. ere' Spiklerne 

 meget smaa, næsen flade og have en forskjellig Form ; 

 nogle nærme sig Kollens, andre Klubbens; de ere fra 0.080 

 —0.100""" lange og fra 0.032—0.068'""' brede i den tykke 

 Ende; Skaftet er paa enkelte langstrakt og 0.012""" bredt, 

 Fig. 26 — 29. Imellem Spindlerne sees mere eller mindre 

 udprægede Valser, fra 0.111 — 0.160"™ lange og fra 0.064— 

 0.072""" brede, Fig. 30. 31, samt særegne, stærkt takkede 

 eller bladede Koller med kurt, takket Haandgreb, Fig. 32; 

 den ene Form af disse Koller er især stærkt indskaaren 

 langs den ene Side, Fig. 33; de ere fra 0.152 — 0.168"'"'

when bruken up into several pieces however, it sometimes, 

 bappens that we are fortunate enough to obtain it. They 



vary in size, from 0.092 — 0.146 in length, and from 0.060 



—0.076""" in breadth; very frequcntly they have a bare 

 mesial part, which, as a rule, is halt' the breadth of the 

 extremities (figs. 4. 5). The fusees are, usually, beset with 

 warts, and are, most frequently straight, but appcar, also, 

 more <>i' less bent; their extremities are, partly, acuminated, 

 partly, blunted, indeed, may also, even, be transversely trun- 

 eated, aud in that case they approach mueh to the roller- 



i'orm: they measure from 0.084—0.128 in length, and from 



0.036—0052 in breadth (figs. 6—11). Between the spi- 

 cules mentiiined, beåutiful bistellates are seen, which measure 



0.080 in length, and 0.052""" in breadth at the extremities, 



and about 0.020' in breadth at the smooth mesial belt (figs. 



12. 13. 14): also a few pedunculated stellales, complex like 

 the quadruplets, and measuring 0.084""" in length, and (Ult id""" 

 in breadth (fig. 15); a few foliaceous subclavates, with Inni;' 

 thin shaft. and measuring 0.156""" in length and 0.060""" 

 in breadth above (fig. 16); foliaceous clavates, with short 



shaft, and measuring 0.096""" in length, and 0.056 



in breadth above ine,-. 17), also, variously formed quadrup- 

 lets, measuring 0.088 in length, and 0.080""" in breadth 



(figs. 18. 19. 20). 



ln the lowest part of the stem. the spicules are placed, 

 more dispersed than in the basal part, and, here, we meet 

 about the same forms as in the latter. The uppermost part 

 is, as before mentioued, devoid of spicules. 



On the body of the polyp, which is rich in spicules, 

 the fusi-form is the most frequent. it appears, principally 

 as spieate, straight or bent, warted fusees, partly, with 

 blimt, partly, with acuminate extremities, and forms, the 

 previously described series on the anterior body, and it is 

 similar spicules which compose the principal bulk of spi- 

 cules on the posterior body (fig. 3). They are of various 

 sizes, measuring from 0.100 — 0.266""" in length, and trom 

 0.036—0.056""" in breadth (figs. 21—25) and, in the situ- 

 ation where the spicular series ceases, at the root of the 

 tentacles, the spicules are very minute, almost flat, and 

 have a variable form; some approach forming of the sub- 

 clavate, others that of the clavate; they measure, from 0.080 



—0.100 in length, and from 0.032—0.068 in breadth 



at the thick extremity. ln a few of them, the shaft is 

 elongate and measures 0.012""" in breadth (figs. 20 — 29). 

 Between the fusees, more or less distinct, rollers are seen, 

 measuring from 0.111 — 0.160'""' in length, aud from 0.064 



— 0.072 in breadth (tigs. 30. 31) also, peculiar, strongly 



spieate or foliaceous subclavates, with short, spieate shaft 

 (fig. 32). The one form of these subclavates is especially 

 distinctly indented along the one side (fig. 33). They measure 



trom 0.152—0.168""" in length, and from 0.056—0076 



in breadth above.
