The trunk of the colony is generally distinct and well developed; not membranous 
at the base. The branches are placed close together and cover the trunk, which is furrowed 
longitudinally. The anthocodiae are arranged on the numerous smaller branches, generally 
in groups of three anthocodiae, of which one is more vigorously developed than the others. 
The small branches lie very close together on the larger ones. The anthocodiae are usu- 
ally short, about 3 mm. long, and strongly bent inwards towards the branches, somewhat 
club-shaped. 
The armature in the anthocodiae consists of clubs and spindles, of which the former 
are most numerous. These spicules are short, broad, and provided with long, broad 
thorns. They attain a length of about 0.2 mm. The spicules are distributed very closely 
and uniformly, and, consequently, the ridges of this species are not so strongly developed. 
The tentacles contain numerous spicules. In the bark of the branches and trunk there 
are short, broad spicules, dumb-bells and crosses up to 0.1 mm., mingled with solitary 
longer spindles and clubs, 0.15 mm. in length. 
The connection between the coelenterons of the anthocodiae is indirect. Direct 
connection appears very seldom and only in the case of a great crowding together of 
coelenterons. The walls of these latter are rather strong and retain a constant thickness 
throughout the whole branch. The indirect canals mostly consist of short, narrow cell- 
strings, which communicate actively with each other and with the coelenterons. The 
non-existence of direct connection is a natural consequence of the distribution of the 
anthocodiae on the branches. The coelenterons of the polyps are also rather short and 
soon disappear, in consequence of which the number of the tubes in the branches be- 
comes insignificant.
