A colony with a long, stout, barren, main stem, divides at the top into two short 
fingerlike branches, covered with polyps. It is near A. palmata Thomson and Simpson, but the 
crown of the anthocodise has six rows of spicules, instead of eight. 
The following points are to be noted : 
(1) Anthocodiae very large. 
Anthocodial armature. Crown — 6 rows of large spicules. 
Points —- 2 large spicules, irregularly placed en chevron, and one or two very much 
smaller ones between. 
(2) Verrucae large, prominent, ledge-like, very crowded at the ends of the branches, none on 
the main stem. 
(3) Anthocodiae retracted. 
(4) Four or live large canals with thin walls. 
(5) Spicules large and colourless spindles, with large multi-tuberculate warts — 3-3 X °-5 mm 
(6) Colour — yellowish-white, with white anthocodiae. 
Previously recorded from the Andamans.

Numerous broken branches all .appear to belong to the same species. The branches 
are pale yellow in colour and slender, with polyps very far apart, occurring all along their 
length. There is very little secondary branching, some branches 3—4 cm. in length only giving 
off one twig, others none. The breadth of the branches is extraordinarily uniform, 2.5 mm. 
The anthocodiae are very heavily armed, especially the points, which have 4—5 pairs of 
spicules arranged in chevron. The two outermost pairs of spicules are very much larger than 
the others-, the crown consist of 5—6 rows of spicules. The verrucae are prominent, in some 
cases 1 cm. apart. Some completely enclose the anthocodiae, in other cases the anthocodiae are 
unretracted. Three large canals, with thin walls, occur in the main stem. 
The spicules are colourless and also yellow, stout spindles, with large compound warts. 
Smaller ones, with simple warts far apart, also occur. Measurements: 1.1 X 2.5 mm., 0.7 X 0.03 mm.

Three interesting specimens with branches in one plane. All branches and sub-branches 
on the same specimen arise at the same angle (6o°—90°), giving the appearance of a series of 
parallel lines. The general build of the colonies is slender, the broadest part of the main stem, 
at the base of the largest colony, being 3 mm., and the usual breadth of the branches and 
sub-branches under 2 mm. Their total heights vary from 9 to 12 cm. Polyps occur on the main
