9. Siphonogorgia duriuscula Thomson and Simpson, 1909. 
(1) Anthocodial armature very distinct. 
Crown — 4 — 6 rows of curved spindles. 
Points — 2 pairs en chevron. 
(2) Verrucae occur all round, formed of about eight spicules which give an irregular toothed 
opening. They are all directed upwards and more developed externally. 
(3) Anthocodiae not retracted. 
(4) Numerous canals in the stem, with thin walls. 
(5) Spicules rather elliptical, covered with very large, close-set, compound warts. 
(6) Small massive colony with lobate branches. 
Colour — general coenenchyma yellowish-pink, crown and points dark crimson red. 
Locality: Cape Comorin. 
10. Siphonogorgia fiavocapitata (= Chironepiitliya fiavocapitata Harrison, 1908). 
See Thomson and Russell, 1910. 
(1) Crown — 6 rows of spicules. 
Points — 2 large spicules and smaller ones irregularly disposed between them. 
(2) Verrucae directed vertically upwards. 
(3) Anthocodiae not retracted. 
(4, 5) Not described. 
(6) Long slender branches, slightly subdivided, tending to droop downwards. 
Colour — Pure white, with a few pink spicules in the stem and branches. Polyps 
deep orange. 
Localities: Admiralty Islands, Providence, Amirante. 
11. Siphonogorgia godeffroyi Kolliker, 1874. 
(1) Not described. 
(2) Cup-shaped verrucae. 
(3) Retracted anthocodiae, verrucae slightly open at the ends, so that in some cases the polyp 
can be seen. 
(4) The centre of the stem is greyish-white and gelatinous, intersected by canals of which the 
largest is in the middle. The walls are like gristle and have a certain number of spicules 
in them. To the outside the rind is red and hard, very rich in spicules. In the smaller 
branches more and more of the stem becomes filled up with wider canals whose walls are 
richer in spicules. 
(5) Some of the spicules may be over 4 mm. in length. Between the canal walls are small 
very red spicules, 0.1—0.15 mm. in length. 
(6) The ends of the branches club-shaped. Polyps only on the thickened ends of tertiary branches. 
Colour — dark brownish-red with yellow polyps. 
Localities: Pelew Islands, Hyalonema Ground Japan, Funafuti.
