The anthocodia' are wholly retractile and when retracted give the surface 

 an undulating appearance. There is a distinct " crown and points " arrangement 

 on the basal portion, the " crown " consisting of two or three rows, the " points " 

 composed of four to six spicules arranged " en chevron ". 



The spicules vary in the different parts and present the following types, 

 with measurements in millimetres : — 



[a) Coenenchyma : transparent, slightly pink or yellowish : — 



(1) Very warty thick spindles, 018 x 008 ; 0*2 x 0-05. 



(2) Warty clubs almost foliaceous, 0-25 x 01 ; 0-2 x 0*05. 



(3) Spindles with very long warts on one side, 0-2 x 015 ; 



2 X 0-12. 



(4) Almost warty spheres, O'l x O'l. 

 (h) Verruca" — same types, very yellow and slightly larger. 



{(■) Anthocodiai: (1) "Crown and points" — slightly warty spindles, pale 



yellow to colourless, 03 x 002 ; 025 x 002. 

 (2) Tentacles — colourless, 0075 x 001. 



Locality : Gulf of Martaban, 67 fathoms. 



There occur also in the collection two fragmentary specimens which we 

 refer to this very variable species. We would therefore add the following notes 

 as to colour, distribution of verrucas, relation of node to internode, etc. 



The larger is 45 mm. in height and 20 mm. in breadth. It is attached to 

 a piece of rock by a spreading base. The branching is a false dichotomy in 

 one plane. The diameter of the lowest internode is 25 mm. while that of the 

 corresponding node is 4 mm. ; the first internode is 4 mm. in length, the fourth 

 is 15 mm. The axial portion of the internode is red, that of the node is 

 brown. The coenenchyma is brownish-red but the polyps are yellow. The 

 polyps occur all round the circumference in an indefinite manner, but in some 

 places they appear only on the lateral aspects. 



Locality : Off Table Island (Cocos) ; Andamans, 16-35 fathoms. 



The second specimen is 35 mm. in height and 25 mm. in breadth. The 

 branching is in one plane and falsely dichotomous. The diameter of the lowest 

 internode is 3 mm. ; that of the corresponding node is 5 mm. The lowest inter- 

 node is 5 mm. in length, while the third is 11 mm. 



The axis is red and grooved ; the nodes are brown and swollen. The 

 polyps occur indefinitely over the whole surface. The colour of the coenenchyma 

 is red, that of the polyps yellow. 



Locality : Andamans, 270-45 fathoms. 



Previously recorded from the Maldives.
