upper portion, 6 cm. high, is almost wholly yellow. It gives off five slender, almost vertical 
branches. Again the anthocodiae are white. Three other specimens occur, which are merely long 
slender branches broken off from colonies. Their colours respectively are white with large yellow 
anthocodiae, salmon pink with white anthocodiae, and yellow with white anthocodiae.

Stat. 260. 5°36 / .5S., I32°55 / .2E. 90 M. Sand, coral and shells. 1 Ex. 
A small slender colony rises straight up, from a base of attachment of 2 mm., to a 
height of 3.5 cm. The stem remains almost the same width throughout, and no branching 
occurs. The lower half of the stem is completely barren, and the upper half is covered with 
polyps at very regular intervals of 3.5 mm. The polyp-bearing portion of the stem is very 
deeply furrowed. The colour of the colony is greyish-yellow, and the anthocodiae are white. 
The crown of the anthocodiae consists of 7 or 8 rows of spicules and the points of 
3—4 pairs in chevron. 
The verrucae are prominent and cone-shaped, and entirely encircle the retracted polyps. 
Four large canals with thin walls occupy the whole of the stem. They are of equal size, dividing 
the stem into four quadrants. A 
The spicules are snow-white, slender, needle-shaped, with pointed ends, and with very 
prominent warts. Many are 1.55 X 0.11 mm. 
The anthocodiae of S. simplex are very near those of A. harrisoni (Th. and R.) and 
A. pallida (Stud.), but the species differs markedly from the former, in having thin, soft canal 
walls instead of stiff walls, thickly filled with spicules, and from the latter in the shape and 
size of the spicules. 
22. Siphonogorgia splendens Kukenthal. 
For description see: KUKENTHAL, Japanische Alcyonaceen, 1906, p. 80. 
Stat. 310. 8°30 / S., H9°7 / .5 E. 73 M. Sand with few pieces of dead coral. 1 Ex. 
A very poor specimen of this species, has a long, broad, barren stem with one short 
polyp-bearing branch at the top. It is ivory white in colour, with orange red polyps, and 
differs from A. variabilis only in the number of rows in the crown of the anthocodia. There 
are to rows in the crown of A. variabilis and only 3—4 rows in A. splendens. Very large 
spicules occur in the verrucae, some of them attaining a length of 2.5 mm. The anthocodiae 
are only half-retracted within the v'errucae. 
Previously recorded from the China Sea.
