This liydroid was dredged from Bird Island, Algoa Bay. 

 It readies a height of 4-5 inches. In the preserved condition 

 it is yellowish white and is very opaque. The gonosome has 

 not been found.

Tliyrosc jphiis sequalis sj). n. 



Trophosome. — Hydrorhiza unknown since the sjiecimen 

 was torn from its base. 



Hydrocaulus. — Thick woody stem, monosiphonic, zigzag, 

 divided into regular internodes which bear at their distal ends 

 alternating hydrotheci^ on short thick processes (text-fig. 

 2S,B). Lateral branches are given off right and left in one 

 plane ; they arise from the internode of the main stem at the 

 back of a hydrotheca (fig. B, h), and consequently the hydro- 

 theca comes to lie, not exactly in the axil, but in front of it.
