(6) Hard, slightly flexible, but rather brittle, owing to the large spicules and the paucity of 
the coenenchyma. Branches arise almost at right angles. Tn the smaller twigs, a long spindle 
may be curved round the verruca, so that the polyp is protected within a small sinus. 
Colour — orange yellow-brown with brown polyps. 
Locality: Funafuti, Caspar Strait. 
21. Siphonogorgia media Thomson and Simpson, 1909. 
(1) Crown and points arrangement very marked. 
Crown •— about 12 rows, which diminish in size as they pass down the neck. 
Points — 2 very definite club-shaped spicules, touching almost throughout their entire 
length, having a curved spindle as a base to the triangle. The small triangle encloses a 
single spicule. 
(2) Verrucae rather prominent, formed by a definite arrangement of large longitudinally disposed 
spicules. 
(3) Anthocodiae retractile. 
(4) Not described. 
(5) Spindles very large, 4.75 mm. in length, covered with multituberculate warts. 
(6) Branches arise perpendicularly from the main stem. The whole colony is stiff and rigid. 
Colour -— creamy-white, slightly pinkish near the base. 
Locality : Andamans. 
22. SipJionogorgia miniacea Kiikenthal, 1896. 
(1) Crown — 4 rows of spicules. 
Points — 3 spicules on one side and 2 on the other, converging at the top. 
(2) Verrucae not very marked, outermost spicules largest, up to 2 mm. Sometimes a modified 
supporting bundle is formed. 
(3) Anthocodiae completely retractile. 
(4) 4 rather narrow canals in the •main stem, with thick walls. 
(5) In the inside of the stem, thick spicules occur (1 X 1.8 mm.), with round toothed warts, and 
also small thin thorny spicules (0.2 mm. in length). The majority of the coenenchyma 
spicules are of the commonest Siphonogorgia shape (1.3x0.14mm., etc.). 
(6) Branches cylindrical, scanty. 
Colour — coral red, with white polyps. 
Localities: Ternate, Ceylon Seas. 
Note. The build of the colony is more graceful than that of S. kollikeri , the coenen- 
chymal spicules are much larger than those of S', pallida , but it is with these two species 
that S. miniacea should be grouped. 
23. Siphonogorgia 7 nirabilis Klunzinger, 1877. 
Crown — (1) 4—6 rows of spicules (Thomson & Simpson, 
(2) 8—10 „ „ „ (Thomson & Russell, 
1909) . 
1910) .
