(4) Not described 
(5) Spicules somewhat loosely packed. 
(6) Branches few, directed obliquely-upwards, not further subdivided. 
Colour — stem bright coral-red, polyps bright yellow. 
Locality: Bay of Bengal. 
35. Siphonogorgia splendens Kiikenthal, 1906. 
(1) Crown — 3 rows of spindles. 
Points — 1 — 2 pairs; if 2, the outer pair larger. Two small spindles between the points. 
(2) Verrucse not sharply differentiated from the polyp. 
(3) Anthocodise not retracted. 
(4) Not described. 
(5) Spicules of verrucse large, up to 3 mm. in length. 
(6) Colour — ivory white, red verrucse and crowns. 
Locality: China Sea. 
Note. This species differs from S. variabilis in the polyp armature, S', splendens has 
only 3 rows in the crown instead of 10, and has 2 small spicules between the points. 
36. S', sqnarrosa Studer, 1878. 
(1) Not described. 
(2) Verrucse at the ends of twigs only, 5 — 6 together. 
(3) Anthocodise completely retracted. 
(4) Not described. 
(5) Most of the spicules of the stem and branches are short and broad, white in colour. A few 
larger ones are red.

37. Siphonogorgia variabilis (= Cliironephthya variabilis Hickson, 1903).

Points — variable, usually four large and prominent spicules en chevron, the two outer 
usually larger than the inner. In the angle of chevron others may occur. 
(2) Verrucse often by no means prominent, may consist merely of a few projecting spicules. 
(3) Anthocodise sometimes retracted, usually not. 
(4) Large canals with thin walls. 
(5) Size and colour of spicules very variable. 
(6) Colour — very variable. Colour of spicules of anthocodise usually in marked contrast with 
those of the coenenchyma.
