Diagnosis : Umbellate; branches in rounded bunches closely packed; general shape flat 
to globose ; polyps on the terminal twigs ; polyp stalks long ; polyps stand out nearly always 
at right angles; supporting bundle very strong with sometimes a single spicule predominating, 
in other cases with two or three of equal length ; point spicules about 3—5 pairs, the uppermost 
elongated, sometimes very pronouncedly, sometimes not so markedly ; grade IV. ; spicules : lower 
cortex has thick, bent, thorny spindles, but no distinct stars. 
Anthocodial Grade and Formula: 
IV = I -j- 4 p -f- o Cr -f- very strong S. B. 
Descriptive Notes: 
Colony as a whole. Four interesting specimens at different stages of growth, the largest 
having the following dimensions: total height 16 cm., height of sterile stalk 6.5 cm., breadth of 
polyparium 9.5 cm. The general branching of the colony is distinctly umbellate in its largest 
forms, but less so in the younger forms, which tend to be much flattened. 
Branching. The branches form rounded bunches, closely packed together and forming in 
the larger colonies a markedly uniform contour. The general shape varies from flat to globose, 
but little importance can be attached to this. 
Colouring. Yellow white, polyps dark red. 
Polyp stalks long. Polyps arranged on the terminal twigs. The anthocodial armature is 
marked by the elongation of one or both of the terminal spicules of each point, the others, to 
the number of 2 or 3 pairs, being markedly subordinate. This is grade IV. 
The tentacles are long and heavily armoured, bearing dorsally a crowd, sometimes 
bilinear, of minute oval or rod-like reddish spicules. 
The supporting bundle is very strong, the largest spindle often projecting for 1 mm. 
The spicules are finely and thickly spinose, and often show smooth points. In many cases one 
polyp and its supporting bundle may be seen to predominate markedly over the others in the group. 
Other spicules. The spicules of the lower cortex are mostly thick spindles, usually bent, 
and densely covered with strong, blunt, thorns, often compound. These bent spindles often 
develop a knee with a marked prominence on the convex side, leading to a distinct bracket¬ 
like form. There are numerous triradiates of a rough type and numerous small capstans. No 
distinct stars* were seen. 
Locality: Station 99. 
Seven other colonies must also be referred to this species. 
(1) A small colony considerably flattened, of a general orange red colour. The spicules of the 
sterile stalk and branches are white, but those of the polyp stem, the supporting bundle, 
and the anthocodiae are orange red. The spicules of the tentacles are bright red and 
catch the eye very markedly. 
Locality: Station 315. 
(2) An almost spherical colony with a bare patch on one side where it had evidently been
