 Suberogorgia kollikeri, var. ceylonensis, Thomson. 



Two slightly damaged colonies 70 mm. x 40 mm. and 65 mm. x 40 mm. 

 in length and breadth respectively. They are of a yellovi'ish-brown colour but 

 the younger twigs are almost grey. Both have discs of attachment and the 

 coenenchyma extends over the rock for a considerable distance. The branching 

 is in one plane but quite indefinite. The crenenchyma is finely granular. The 

 polyps occur mainly on the latei'al aspects of the branches, but on the older 

 parts they are disposed all round ; they are absent, however, on the lower part 

 of the main stem. The verrucre appear as warts flattened in the plane of rami- 

 fication and give the surface an undulating contour. The spiculation and 

 other details agree with those given for the type in the " Ceylon Pearl Oyster 

 Fisheries Report," Appendix D. — Alcyonaria. Supp. Report XXVIII. 



Locality : Andamans, 270-45 fathoms. 



S. kollikeri, previously recorded from Japan, "Challenger"; var. ceylon- 

 ensis, Ceylon Seas, Herdman ; var. Zanzibar ensis, Zanzibar, Crossland. 



Suberogorgia verriculata, Esper. 



Several magnificent specimens of this well-known species occur in the 

 Wood-Mason Collection. The largest is over 300 mm. in height. All are 

 expanded in one plane. The colovu' varies from creamy white to brown when 

 in spirit. The abundant anastomosis and the distinctive anthocodiai give the 

 colony a characteristic appearance. 



Previously recorded from Jaj^an and Australia. 



Suberogorgia ornata, n. sp. Plate II. figs. 7d and 7b. 



We refer to this new species a number of specimens from different localities. 



All are of a brownish colour except in certain places where there are 

 segregations of small spicules on the surface which present a white glistening 

 appearance. The two largest colonies measure 150 mm. in height by 70 mm. in 

 breadth, and 140 mm. in height by 70 mm. in breadth ; the second is the more 

 perfect specimen. They are branched in one plane and anastomose freely forming 

 an open network. The thickness of the stem and branches hardly varies
