(2 — 5) Not described. 
(6) Short thick branches given off all round the stem. 
Colour — deep crimson shaded to buff yellow. 
Locality: Admiralty Island. 
3. Siphonogorgia asperula Thomson and Simpson, 1909. 
(1) Crown 3 — 6 rows of large spindles with a few rows of smaller ones in the oesophageal region. 
Points — 2 very strong spindles bent at the base with one or two small ones between. 
(2) Slightly projecting verrucae, composed of a few large longitudinal spicules. In some cases 
unsymmetrical cylinders are strengthened externally by two sheaves like “supporting bundles”. 
(3) Polyps unretracted. 
(4) Numerous canals in the stem with very thin partition walls. 
(5) Stout and slender spicules with large warts. 
(6) Massive with numerous short branches, verrucae mainly on short branches and tip of stem. 
Localities: Cape Comorin, Andamans. 
4. Siphonogorgia collaris Nutting, 1908. 
(1) Crown — broad and conspicuous? 
Points — a few spicules arranged en chevron, and then a few longer and more slender 
spicules, which are outside of the latter and curved to meet each other, so that their distal 
ends are parallel to the axis of the tentacle; the whole forming a high operculum. 
(2) Verrucae prominent (3.5 mm. high), tubular, narrowing gradually at the distal end. 
(3) Anthocodiae retracted. 
(4) Canals numerous and irregular with long and minute spindles in their walls. 
(5) Spicules densely covered with minute tubercles, appearing granulated. 
(6) Polyps thickly clustered over the entire surface (only a fragment was secured). 
Locality: Off Laysan Island. 
Note. A. collaris differs'from S. kollikeri in having much more exserted and more 
crowded calyces. 
5. Siphonogorgia crassa (= Chironephthya crassa Wright and Studer, 1889). 
(1) Not described. 
(2) Verrucae large, and obliquely projecting. 
(3) Polyps more or less retracted. 
(4) Canals wide, bounded by thin walls. 
Locality: Hyalonema Ground, Japan. 
Note. No details of the anthocodial armature were given by Wright and Studer, but 
Hickson, having examined the type specimens in the British Museum, (The Alcyonaria of the 
Maldives, 1903), is convinced that the species S. dipsacea , S. crassa , S. scoparia are one and 
the same thing, and also identical with A. variabilis (Hickson). In this case, the crown consists 
of about 10 rows, and the points have 4 main spicules arranged en chevron with smaller
