Anthocodial Grade and Formula: 
III = 4—5 p -f- o Cr -j- strong - S. B. 
Descriptive Notes: 
Colony as a whole. Eight young colonies, the largest of which is 6.5 cm. high. They 
are very flaccid in texture and hyaline in appearance. The youngest forms show little hint of 
umbellate branching, but this is well marked in the biggest. As the umbels do not compose large 
hemispherical groups, the specimens should be referred to section B of Kukenthal’s Umbellatse, 
and the presence of unequally long branches, resulting in no very uniform outline, points to 
the spinulosa-gvou\). 
Branching. There is a distinct foliaceous collar. Branches unequal. 
Colouring. Cortex very hyaline, bearing loosely disposed white spicules. 
Polyp stalks. Slightly over 1 mm. long. 
Polyps. Few are in good condition, owing to the colonies having been in most cases 
much compressed; the polyps occur in small bundles of three or four. The anthocodial points 
consist of 4—5 pairs en chevron, with almost no specialisation of the uppermost pair. 
The supporting bundle is fairly well developed, and the strongest spicule may project 
for half a millimetre. 
Other spicules. The sterile stalk shows numerous stellate and multiradiate spicules.

Diagnosis: Umbellate; contour irregular; basal branches foliaceous and forming a collar; 
polyps arranged in small roundish masses: polyp stalks long; supporting bundle very strong; 
point spicules 5—6 pairs with one of the uppermost pair stronger and sometimes projecting; 
grade IV.; spicules: very abundant spindles on the polyp stalks; on the polyps, but not on 
the collar, sigmoid spindles; on the collar irregular interlocking quadrangular “crosses”. 
Anthocodial Grade and Formula: 
IV = 5—6 p F o Cr T very strong S. B. 
Descriptive Notes : 
Colony as a whole. Two colonies, of which the larger is, as regards the polyparium, 
9.5 cm. high, 12 cm. broad, and 5 cm. in thickness. 
Branching. Umbellate, referable to Kukenthal’s subsection with the umbels forming large 
hemispherical masses, and to the collaris-g roup, where the contour is broken by the clefts 
between the masses. It differs markedly in having only a short stalk, but this is probably only 
a growth condition related to the nature of the substratum. At the top of the short stalk the 
basal branches are foliaceous and form a collar. 
Colouring. Polyps of the foliaceous collar are bright red ; those of the rest of the colony 
white (not purple as in the “Challenger” specimen), but some of them show a tinge of red. 
Polyp stalks are long. They are covered with spindles almost en chevron. Polyps
