greatly as to regularity in eight rows and also as to degree of projection ; the 

 cylindrical forms are about 3 mm. high and r2.") mm. in diameter, the others 

 are about 3 "5 mm. high, 125 mm. in basal diameter, and 15 mm. in apical 

 diameter. 



G. A number of colonies laxly branched in one plane ; ccenenchyma moder- 

 ately thick ; verrucee elongated, slender and expanded at the apex, 3 5 mm. high, 

 1 mm. in basal diameter, and 1"5 mm. in apical diameter ; they occur thickly but 

 are not crowded. Colour — pale brown. 



Localities : A — Marble Rocks, Mergui ; B — off Malabar Coast, 31 fathoms ; 

 C — Andamans ; D — off Cape Comorin, 38 fathoms ; E — off Gopalpur, Coro- 

 mandel Coast, 14-15 fathoms ; F — off Malabar Coast, 36 fathoms.

GENUS ANTHOGORGIA, VERRILL. 



This genus was established by Verrill to include a colony which previ- 

 ously he had referred to Mitrieea. Thus AnthQcjanjia divancata, Verrill (" Amer. 

 Jour, of Science and Art," vol. xlv. p. 412, \^i'ii<) = Marken dmuimta, Verrill 

 (" Proc. Essex Inst.," vol. iv. p. 188, PI. V. figs. 5 and (3, 1865). The following 

 is his diagnosis of the genus : Authogorgla — characterised by tery proniinent 

 tubular cells, dght-rayed at the summit ; thin ccenenchyma containing embedded 

 fusiform spicula, those of the cells long, fusiform, thorny, imbedded at various 

 angles in the surface but not imbricated. 



Wright and Studer in the " Challenger" Report, vol. xxxi. p. liii., give the 

 following diagnosis : Colony is branched with slender elongated branches. The 

 polyp calyces are strongly projected, of a tubular form, with an eight-rayed 

 operculum consistinp of a thin ectoderm in which large long spindles are em- 

 bedded at various angles. The ccenenchyma is thin with large warty spindles. 



The following species are known and described : — 



A. divan'cata, Verrill, "Proc. Essex Inst.," vol. iv. p. 188; from W. 

 Australia and Hong Kong. 



A. verrilli, Thomson and Henderson ; from the Andamans, 270-45 fms. 



In the Supplement to the "Challenger" Report (1889, p. 12), Studer 

 described a specimen under the name of Anthogorgia japonica, but as the 

 operculum is tentacular and not ealycine it must be excluded from this genus. 



Anthogorgia glomerata, n. sp. Plate II, fig. 8 ; Plate III. fig. 11. 



This species is represented by a very ragged fragment of a remarkable 

 colony. It is branched in one plane and anastomoses freely ; it ineasures 6 cm.
