6. Polyp sjHcules. The aiithocodial armature of 8-10 pairs of 

 white spicules, closely opposed en chevron with no more than a 

 hint of projection, is the salient feature 



of the colony. Owing to their white Text-fig. 17. 



colour these spicules stand out very 



conspicuously. Their surface is covered 



irregularly with minute tubercles, which 



are much more crowded towards the 



tips. 



The supporting bundle is strongly 

 developed, its largest spicules projecting 

 for 0*75 mm. 



7. Other spicules. The stem has 

 loosely disposed spindles, many of them 

 having only minute and rather distant 

 spinules. These tend to be slender. 

 Those of the surface of the sterile stalk -D. klunzingeri Stud. 

 show a stronger development of thorns. 



There are, besides spindles, many irregular triradiates, quadri- 

 radiates, and brackets. 



Kiikenthal lays stress on the great reduction of the sterile 

 stalk. This is far from the case in this specimen, where it 

 occupies 1*5 cm. out of a total height of 4 cm. From what I 

 have seen in other cases, I do not think that the proportion of 

 stalk to polyparium is of much importance. 



Kiikenthal also notes that the outermost polyps bore markedly 

 projecting spicules at the tips of the points. Of this feature this 

 specimen shows no more than a trace ; but on account of the 

 characteristic anthocodial armature, I cannot separate it from 

 D. kluvzingeri.
