The outermost internodes may reach a considerable size, the largest being about 75 mm, and are usually provided with several zooids. The largest number noticed was 19 zooids on a 73 mm long inter- node. The largest branches are about SO mm and are found in colonies which ])robably may have measured 25-3n cm in height; often these branches bifurcate but once with the inner internode measuring about 5 mm and the outer aliout 7.'> mm. The angle of bifurcation is generally about ti()'-7() ami may narrow down to about 50°. The zooids measure in contracted state (verrucae) al)out (2-3) nnii in height having a width of nun.
