Stat. 315. Anchorage East of Sailus Besar. Paternoster-islands. Up to 36 M. Coral and Litho- 
thamnion. 2 Ex. 
Diagnosis: Divaricate; firm; lowest branches slightly foliaceous; polyps in divergent 
groups of 4—10; polyp stalks long; supporting bundle strong; point spicules 6 — 8, small, 
close-set, the uppermost pair predominating and slightly projecting; no pseudo-crown ; grade II.; 
spicules: in the tentacles a double row of transversely arranged, narrow, jagged spicules; in the 
cortex of the sterile stalk thick, bent, warty spindles and quadrangular bodies. 
Anthocodial Grade and Formula : 
II. = I P -j— 5 — 7 p -f- o Cr fl- strong S. B. 
Descriptive Notes : 
Colony as a whole. A somewhat firm young colony with a long, limp stalk; total length 
5 cm., of which 1.5 is polyparium. 
Branching. The lowest branches show only a hint of being foliaceous. 
Colour. A fine coral-red in stalk, supporting bundle, polyp stalk, and tentacles; the 
general cortex of the polyparium is white flushed with red, and the anthocodial spicules are white. 
Polyp stalks long. 
Polyps in divergent groups of 4—10. 
Polyp spicules. The armature of the anthocodise consists of eight points of small spicules, 
very compactly disposed, 6—8 e n chevron in each point; the uppermost pair in each row 
predominate and may project slightly. 
The supporting bundle is strongly developed, and one strong central spindle projects for 
1 mm.; the spicules here are thickly but finely spinose. 
Other spicules. The tentacles show a double dorsal row of transversely disposed, narrow, 
jagged, reddish spicules; the cortex of the sterile stalk has thick spindles, usually bent, covered 
with large warts, often compound. Along with these are smaller bent spindles, often with large 
prongs on the convex side. There are also numerous bright red, irregularly quadrangular or 
knob-like corpuscles, which may be vaguely called “stars”. These are well figured by Putter. All 
these stalk spicules with prongs are suited for interlocking. 
Perhaps the most characteristic features are (1) the numerous compact chevron pairs of 
the anthocodial points, and (2) the quadrangular “stars”. 
Locality: Station 315. 
Two other colonies agree in the anthocodial armature and in having quadrangular “stars” 
in the cortex, fl'hey differ in colour and the proportion of stalk to polyparium, but little importance 
can be attached to either of these points. 
(1) In the first colony the stalk is 3 cm. long and the polyparium 3.5 cm. in height. The lowest 
branches are distinctly foliaceous and are of an orange colour. The smaller twigs are chocolate 
red. The spicules of the anthocodise are either orange or chocolate red according to their 
position in the colony. 
Locality: Station 99. 
(2) In the second colony the sterile stalk is short — less than the height of the polyparium. 
This specimen is distinctly suggestive of an umbellate. The spicules of the general ccenen- 
chyma are orange; those of the supporting bundle are white or tinted with orange; those
