Several specimens from various stations agree most nearly with X. fusca. 
In a typical one from Station 33 Bay of Pidjot, 3 cm. in total height, the stem splits 
near the base into three very smooth fleshy branches which re-divide at the summit into two 
short polyp-bearing twigs. The longest branch has a height of 10 mm. and a maximum diameter 
of 6 mm., while a twig is 5 mm. in length. Most of the twigs however do not exceed 3 mm. 
The soft flaccid polyps are very densely clustered on the summits, with numerous young buds 
near the outer margin, giving a markedly soft fluffy appearance. The polyps are up to 6.5 mm. 
in length and 1.5 in breadth, but a common length is 3 mm. and breadth 1 mm. The tentacles 
vary greatly in length according to the state of contraction, the average length being about 
3 mm. In this specimen the most fully expanded tentacle had a length of 5 mm. and a breadth 
of 0.6 mm. They bear three rather irregularly arranged rows of 12 — 14 pinnules on each side of 
the mid line, which is often quite obscured. In a fully expanded tentacle the three rows may appear 
to merge into two, but three is the more typical. The pinnules of the upper half of the tentacle 
when fully expanded are rather elongated cone-shaped; near the base they approach to low warts. 
Numerous disc-like spicules are found throughout the colony. The colour is a greyish-cream. 
In another colony from Station 33, 4 cm. in total height, the trunk gives rise to two 
main branches one of which gives off four polyp-bearing twigs at different levels, while the 
other gives off five twigs, which may redivide. The colour is a more definite dull brown. 
A small withered colony from the same station is a dark brown. 
A colony from Station 123, stained a slight pink with eosin, shows very fully expanded 
tentacles, on which the pinnules nearly all appear as if in 2 rows. The same type of branching 
and fluffy polyp clusters are seen. 
A curious little colony from Station 282 shows two elongated stems, one with a slight 
basal disc, connected by a stolon which is continued by itself for 1.3 cm., and ends blindly. 
The rather flaccid stems are both about 3 cm. in length and very narrow in proportion, the 
maximum diameter being 3 mm. One gives oft' a polyp-bearing twig, three mm. from the tip. 
Both bear a terminal cluster of slender flaccid polyps which have tentacles with six rows ot 
pinnules about 12 — 13 in a row. None of the pinnules are fully expanded. The maximum 
length of polyp is 5 mm. X 0.9 mm.
