Øverst paa Stammen og Grenene, hvor Spiklerne

 disse Spikler ere dog takkede Spindler med dels tilspidsede,

Paa Polypkroppen. især paa Bygsiden, ligge Spiklerne 

 temmelig kompakte og beståa væsentlig af Spindler og 

 Koller. Spindlerne ere takkede, dels krumme, dels lige.

the summit. On tbe middle part of the stem. bistel- 

 lates which measure 0.1 00""" in lengtb, and 0.040""" in 

 breadtb. (fig. 50); spicate, and warted subclavates, measuring 

 0.120""" in length. and 0.052""" in breadtb at the thick 

 extremity (figs. 51. 52); further, also. spicate fusees with 

 blunted extremities, measuring from 0.060—0.120*"™ in 

 length. and from 0.016 — 0.040™™ in breadtb, are seen to 

 be the most frequent. But. between them. a fev quadru- 

 plets are fouud, like those of the basal part; protuberated 

 bour-glass formed quadruplets. measuring 0.088™ in 

 length. 0.064"™ in breadtb at the extremities. and 0.016""" 

 in breadth at the middle (fig. 53); smootli. hour-glass 

 formed quadruplets. measuring 0.032™" 1 in length, and 0.016' 

 in breadtb at the extremities. and 0.008™™ in breadtb at 

 the middle (fig. 54): extremely minute protuberated almost 

 cruciform. quadruplets. measuring 0.040™™ in diameter 

 (fig. 55). but these last inentioned are extremely rare; 

 finally, a. few pennately dilated. spicate fusees are found, 

 measuring 0.060' in Length, and 0.016""" in breadth 

 (figs. 56. 57. 58 . 



On the uppermost part of the stem and on the 

 branches, where tbe spicules are placed more dispersed. 

 tbey are ricb in forms. Quadruplets are. here, most fre- 

 quent, for instance. cruciform protuberated quadruplets. 

 with a longitudinal arm measuring, 0.088™™, and a trans- 

 versal arm measuring 0.060™™ (fig. 59); a protuberated 

 quadruplet in tbe form of an bour-glass. measuring 0.072™"' 

 in length. and 0.032"'"' in breadtb at tbe extremities. and 

 0.020 broad at the middle (fig. 60); ;i spicate bour-glass 

 formed quadruplet measuring 0.060™ m in lengtb. 0.040""" in 

 breadtb at the extremities, and 0.020™™ broad at tbe middle 

 (fig. 61); a quadruplet in form of a star. having broad rays 

 of about the same length as breadth, and measuring 0.060 ' 

 in diameter (fig. 62) ; an aculeated twin. with bifurcated ex- 

 tremities. and measuring 0.060™™ in length. 0.036""™ in 

 breadth at the extremities, and 0.012""" broad at the middle 

 (fig. 63); but. more frequent than any of the spicules inen- 

 tioned. are. hovvever, spicate fusees with. partly. acuminated 

 and partly. blunted extremities (figs. 64. 1 '>•"> i also. short foliaceous 

 subclavates i fig. 66). The fusees measure from 0.080— 0.100 

 in length. and from 0.016 -0.020""" in breadtb, and the sub- 

 clavates measure 0.080""" in length. and 0.040""" in breadth

< >n the body of the polyp. especially on the dorsal 

 side. tbe spicules are placed pretty compactly. and consist. 

 principally. of fusees and subclavates. The fusees are spicate. 

 partly hent, partly straight, and have both acuminatsd 

 and blunted extremities; tbey measure from 0.128 — 0.22i>'"" 



in length. and are about uniform in breadth, viz. 0.040 at 



the middle (figs. 67 — 70). The subclavates are not so frequent 

 and are, partly. smaller than the fusees; tbey are likewise 

 spieate, and measure 0.080™™ in length. and 0.032""" in 

 breadth above (figs. 71. 72). Between these S2)icules, esriec- 

 ially on the anterior body. occasional quadruplets are 

 observed. of which a few have a rather distinguished 

 cruci-form. with a longitudinal arm measuring 0.080 — 

 0. ISO""» in length. and a transversal arm measuring from
