Of polyjis — red, curved and club-shaped sjiiny spindles of "crown and 

 points," 07 nuu. x 005 mm. ; Oo mm. x 0'035 mm. lied irregular 

 ragged discs of the tentacles, 015 mm. x 002 mm. ; 01 mm. x 0025 

 mm. 



Colour — general c(cnenchyma yellow, i>olyps — bright red. 



Locality : Andamans. 



(F) A beautiful complete colony 5 5 cm. in height and 2"5 cm. in maximum 

 breadth. 



It consists of a main stem with a slightly spreading base from which branches 

 arise at indefinite intervals. Immediately above the base several very small 

 branches come off, but further up larger and more robust offshoots arise at very 

 acute angles. This feature is very marked in the case of one polyp-bearing 

 branch which extends parallel to the main stem throughout its whole 

 course. 



A dense covering of large spicules, arranged for the most part longitudinally, 

 extends over the whole surface of the colony. 



The colour of the general cosnenchyma is a creamy-white, but the bright 

 red anthocodite are prominent and are scattered over the whole colony. They 

 are retractile within verruca^ which are by no means prominent, consisting of 

 a few projecting spicules irregularly arranged. The verruca? measure about 5 

 mm. in diameter. The " crown and points " arrangement is very distinct, the 

 " crown " consisting of six to eight rows of curved spindles, while in each 

 " point " there are two large club-shaped spindles with a few very small ones 

 between. 



The polyps are scattered at fairly wide intervals over the branches but 

 appear as if clustered at the tips. 



The spicules of the cojnenchyma are very large, densely warted, pale yellow 

 sj)indles, straight and curved, and give the following measurements length by 

 breadth in millimetres : 5 x -55 ; 4'5 x 0"5. 



Smaller spiny spindles measure about 0'9 x 0-075. 



In the polyps the spicules are red, curved and club-shaped spindles of the 

 following dimensions in millimetres : 0*35 x 0'02 ; 0*4 x 0'03. 



Locality : Andamans, 270-45 fathoms. 



(G) A small colony, S cm. in height by 5 '5 cm. in breadth, with quite 

 irregular brandling. The branches are short and thick with the polyps clustered 

 chiefly around the blunt end. General colour — brown. Polyps — dark rerl. 

 Arakan Coast, 13 fathoms. 



(H) Another .small colony, 3*5 cm., 1-5 cm. Main stem 1 cm. in breadth, 

 having but a few lobes. General colour, sulphur-yellow ; polyps — red ; ten- 

 tacles — yellow. A note attached to it reads ; " Sulphur-yellow stem, deep 

 maroon (?) florets, yellow centre ".
