(4) The branches have a few large canals separated by thin walls. The stem has smaller 
canals in larger numbers, separated by thick walls of mesogloea in which small spicules 
are imbedded. 
(5) Spicules of coenenchyma long, stout, warty, with rounded ends, orange to yellow in colour, 
visible at once to the naked eye. Smaller spicules in the walls between the canals. 
(6) Stem and branches somewhat flattened. 
Colour -— coral-red with white anthocodiae. 
Note: Thomson and Russell, 1910. Var. rngosa. 
(1) More massive than S. kollikeri Wr. and St. 
(2) Polyps project more conspicuously. 
(3) Anthocodiae the same. 
(4) Spicules longer and more slender; warts smaller, simpler and more scattered. Colour vermilion 
with occasional crimson tinge, instead of strong orange to yellow. Spicules sparser on the 
stem and more irregular. 
Localities: Providence, Amirante. 
19. Siphonogorgici m a crosp ic u lat a 
(== Chironephthya macro spiculata Thomson and Henderson, 1906). 
(1) Crown — 3—4 rows of spicules. 
Points — 2 principal spicules slightly inclined to one another and 2 smaller ones in the 
angle between. There may be 4 large ones. 
(2) Small platform-shaped verrucae formed by several spicules placed side by side, at an acute 
angle to the branch. 
(3) Anthocodiae may be retracted, but not always. 
(4) Not described. 
(5) Spicules red or colourless, may reach over 8 mm. in length. 
(6) Singularly rough surface owing to the presence of large white spicules, the interstices 
between them being filled up with smaller red or colourless ones. 
Colour — light or reddish brown with a streaky appearance. 
Localities: Indian ocean, Malabar Coast, Salomon. 
20. Siphonogorgici macrospina Whitelegge, 1897. 
(1) Crown — several rows. 
Points — 6—8 spicules en chevron. 
(2) Verrucae rudimentary, more of a projecting ledge than a distinct cup. The anthocodiae thus 
appears to arise obliquely from the support. 
(3) Anthocodiae not wholly retracted. 
(4) Walls of canals thickly charged with long thin spiny rods and spindles. 
(5) Spicules on twigs very long, up to 6 mm. in length, those on the main stem stout and 
short. They are covered, in some cases, with large warts close together, and in others with 
spines.
