GORGO NAC Ii A, AND SOME NOTES ON THE SUBEKOGORGIID/E. 229 



Finally let it be noted that in Gorgonian colonies there never 

 exists an axial polyp, which might have taken lead in forming the 

 stems and branches. As I could prove in a previous paper, the axis 

 does not protrude into the ccelenteron, but lies always beneath the 

 entoderm that covers the pedal disc of the mother or axial polyp. 

 In the case of Kerocidcs the relation between axis and terminal 

 polyp is likewise never so intimate that the conception of a leading 

 polyp is scarcely admissible. That the coenenchyma should be re- 

 garded in the light of stolons, seems to stand almost beyond question.
