resting on a rock. The sterile stem and branches are white, but the polyp armature is pale 
orange. The projecting tips of the supporting bundle are often tinted orange. 
Locality: Station 274. 
(3) A small colony identical with the specimen from Station 99. 
Locality: Station 258. 
(4) Two small colonies identical with (3). 
Locality : Not recorded. 
(5) A small colony : the spicules of the sterile stem are red, those of the main branches white, 
those of the secondary branches, the supporting bundle, and the polyps, red. The whole 
colony is rather open, not nearly so compact as the preceding, but the anthocodial structure 
is identical. 
Locality: Not recorded. 
(6) A large colony with a sterile stalk 4.5 cm. long and 2.5 cm. in diameter. The polyparium 
is 10 cm. high and 9.5 cm. wide. It is distinctly lobose. The lobes are confluent, giving the 
colony an undulating appearance. This specimen closely resembles the large specimen 
referred to by Sherriffs.

For three rather perplexing umbellate specimens from Station 274 we have been com¬ 
pelled to establish a new species, D. r^lbesce1^s. 
Anthocodial Grade and Formula: 
V = 3—5 p -f- 2 Cr -}- very strong S. B. 
The three colonies are all about the same size, the largest has a sterile stalk 1 cm. 
long. The polyparium is rounded and not markedly flattened. It is 4.5 cm. in height and 3 cm. 
in diameter. The whole colony has a mottled appearance; some of the polyps are red, others 
are white, while in some the spicules are partly red and partly white. The contour is not 
regular, but marked by large and small indefinite depressions. 
This new species is in the close vicinity of D. coronata , with which it agrees in the 
following features: 
(1) the anthocodial armature consists of 3—5 pairs of slightly kneed spindles arranged en 
chevron. Of these the two uppermost are strongest. Towards the base in the more 
contracted polyps, the lowermost pair or two pairs approach a horizontal position and so 
give the appearance of a pseudo-crown ; 
(2) between each point there occur small intermediate spindles; 
(3) the supporting bundle is strong but simple, and very coherent; it is mainly due to a single 
needle often 3 mm. in length, which may project for 0.5 mm. ; 
(4) the polyps occur in bundles of 6—12, and these with the neighbouring bundles form close 
irregular concave groups. It is this feature which accounts for the indefinite depressions in 
the polyparium.
