Transparent spicules of the coenenchyma, 2'8 mm. x 0'3 mm. ; 2"55 mm. x 



0'25 mm. ; 1'2 mm. x 0-25 mm. 

 Purple spicules of the coenenchyma, 2-7 mm. x 0"25 mm. ; 2"5 mm. x 0'3 



mm. 

 Club-shaped and curved pale yellow spicules of the " crown and points," 



055 mm. x 004 mm. ; 05 mm. x 005 mm. ; 055 mm. x 005 mm. 

 The colour of the general ccenenchyma is pale brown merging into purplish- 

 red in the polyp-bearing branches. The polyps are of a bright yellow 

 colour. 

 Locality : Table Island (Cocos), Andamans, 15-35 fathoms. 

 (C') An almost complete specimen 6 em. high and lii) cm. in breadth. The 

 main stem, which is liroken, is 1'5 cm. long and 07 em. in diameter. In the 

 lower part small branches are given oft" but ultimately it divides into three almost 

 equal branches about the same level. These again bear secondary branches on 

 which are borne the polyps. 



Spicules: Of coenenchyma — transparent warty spindles, 15 mm. x 0"25 

 mm. ; 1'8 mm. x 03 mm. 

 Yellow warty spindles, 2'5 mm. x 0'4 mm.; 1'8 mm. x 0"25 

 mm. ; 15 mm. x 01 5 mm. 

 Of polyp — "crown and points" — pale yellow spiny spindles, 0'6 mm. x 0'05 



mm. ; 0'55 mm. x 0'045 mm. 

 Tentacles — red spiny spindles, 0"1 mm. x 002 mm. ; 0-14 mm. x 0"015 mm. 

 Colour — General coenenchyma — yellow ; " crown and points " — yellow ; 



tentacles — red. 

 Locality : Table Island (Cocos), Andamans, 15-35 fathoms. 



(D) A single slightly damaged specimen attached to a piece of rock by a 

 basal expansion of 2'1 cm. and measuring 8 cm. in height by 4-5 cm. in breadth. 

 On the main stem, which is 1-5 cm. long and 07 cm. in diameter, small branches 

 arise near the base, higher up three almost equal branches are given off and 

 from these arise the secondary branches which bear the polyps. 



Spicules: Of ccenenchyma — transparent and pinkish warty spindles. These 



vary from 23 mm. x 03 mm. to 05 mm. x 004 mm. 

 Of polyps — transparent and more irregular spiny spindles of the "crown 



and points," 0'4 mm. x 0'05 mm. ; O'O mm. x 0'04 mm. 

 Colour — Pinkish tint near the base but grey in the main stem and branches, 



merging gradually into a dull red near the tips of the secondary 



branches ; polyps — white. 

 Locality : Andaman Sea, 41 fathoms. 



(E) Several small fragments of secondary branches of exquisite colouring. 

 Spicules : — Of ccenenchyma — pale yellow warty spindles, P5 mm. x 02 nun. 



to 0"25 mm. x 02 mm.
