Another colony from Station 99 must be referred to this species. In its anthocodial arma¬ 
ture, spiculation and colour, it is identical. 
Locality: Station 99. 
A small divaricate flattened colony agrees with the two specimens described above, except 
in colour. The anthocodial armature is identical, as also are the spicules of the sterile stalk. 
The general colour is white., but the stalks of the polyps pass from white to red ; the terminal 
half of the supporting bundle is reddish, and the spicules of the anthocodiae are bright red. 
Locality: Station 260.

Diagnosis : Divaricate; contour regular; not flattened or only slightly; polyps in groups 
of about 10; polyp stalks medium; supporting bundle very strong; point spicules 4 pairs with 
the uppermost pair (or one of that pair only) strong and projecting ; grade IV ; spicules : stalk 
has rough spindles, triradiates and quadriradiates. 
Anthocodial Grade and Formula: 
IV = 1 — 2 P-Fyp + oCr-F very strong S. B. 
Descriptive Notes : 
Colony as a whole. Four whitish colonies, two of them young or fragmentary. 
Branching. Divaricate, of regular outline, not flattened. Should be referred to Kukenthal's 
divaricala-group, within which they approach D. mollis. 
Colouring. General surface white, anthocodial armature and supporting bundles reddish 
brown in the largest specimen. In the two younger colonies the anthocodial and supporting- 
bundle spicules are amber-yellow. The fourth colony is ivory-white. 
Polyp stalks about 1 mm. long. ‘ 
Polyps arranged in groups of about ten in number. 
Polyp spicules. One of the uppermost pair of spicules in at least some of the eight points 
is strong, out of proportion to the others and projects very markedly beyond the polyp. The 
other spindles of the points are small and converging, and there may be four pairs of them. 
In many cases the large projecting spindle has fallen off, and its attachment seems to be 
very loose. 
The supporting bundle is very strongly developed and 3 or so of its component spicules 
project beyond the polyp for over 1 mm. The spindles are densely and regularly covered with 
very small blunt tubercles, while here and there almost smooth forms occur.
