(6) the eight anthocodial points are often elongated and have the tips meeting over the polyp ; and 
(7) the lowest branches of the colony show slight foliation. 
The collection also includes eight other specimens (from three stations) which we refer 
to this species. 
(1) A small flattened conglomerate colony 10 cm. high and 5 cm. across. The spicules of the 
general cortex are white or porcellanous in the main stem, but reddish in the smaller 
branches. The anterior half of the main spicule of the supporting bundle is white, while the 
basal portion is red. The spicules of the polyps are yellow. 
Locality: Station 258. 
(2) Two small upright conglomerate colonies similar in branching and size to the preceding. 
The general colour is orange but the tips of the spicules of the supporting bundle are 
white and give the colonies a very spiny appearance. 
Locality: Station 315. 
(3) A markedly conglomerate colony sparsely branched. The general colour is reddish orange. 
The main spicule of the supporting bundle is sometimes red throughout, but sometimes 
white in the lower half. 
Locality: Station 123. 
(4) Two small upright conglomerate colonies slightly more branched than those from Station 258. 
They are about 6 cm. high by 5 cm. in breadth. They are identical in coloration, as are 
also two fragments. The locality is not recorded, but it is possible that they came from the 
same station (258). 
Previously recorded from Japan and Hong Kong.

Diagnosis: Glomerate with numerous flnger-like polyp-bearing lobes ; polyps densely 
arranged in hemispherical masses; polyp stalks very short; supporting bundle strong; point 
spicules 4 — 6 pairs; no true crown ; Grade III ; Spicules include very thorny spindles straight 
and curved, short thick derivatives of the spindle type with prominences exaggerated on one 
side, very irregular thorny forms and occasional somewhat regular four-rayed small forms. 
Anthocodial grade and formula : 
III = 4 — 6 p + oCr-f- strong S. B. 
Descriptive Notes: 
Colony as a whole. Four colonies, the largest from Station 272 and three young colonies 
from Station 164. 
Branching. In the largest the sterile stalk is short, but much expanded at the base. From 
this arise a number of stubby branches which bear the finger-like polyp-bearing lobes. The 
polyparium is 5 cm. wide and 2 cm. in height. The largest of the 3 young colonies is 2.5 cm. 
in height, of which about half is sterile (Plate 1, Fig. 2). 
Colouring. In the specimen from Station 272 the coenenchyma is white but the polyps 
have a distinct reddish colour. Examination with a lens showed, however, that some of the
