ANTIPATHES. POLYPI. 427 



Inhabits Indian, American, and Mediterranean seas. Ellis, Cor. 

 pi. 26, fig. A. 



G. verriculata, Lam. Branched, fan-shaped, very large; ramuli 

 divaricate, joined at the reticulations ; crust white, pores warty, 

 scattered. Inhabits Indian seas. One of the largest species. 

 Ellis, Zooph. pi. 17- 



2. Cells cylindrical or turlinalcd, much projecting. 



G. lima, Lam. Branching, dichotomous, whitish ; papillae small, 

 densely clustered, branches compressed at the axis. Inhabits 

 West Indian seas Lam. ii. 322. 



G. lepadifera, Lin. (G. reseda, Pall.) Branching, dichotomous ; 

 papillae clustered, reflexed, campanulate, squamose, subimbrica- 

 ted. Inhabits Northern seas. Ellis, Zooph. pi. 13, fig. 1, 2. 



Gen. 9. ANTIPATHES, Lam. 



Polypiferous mass fixed, branched, composed of a central axis 

 and outer crust ; axis with a foot, and fixed by the base, cau- 

 lescent, simple or branched, corneous, solid, flexible, gene- 

 rally rough with small spines ; crust gelatinous, polypiferous, 

 covering the axis and its branches when alive, but fugacious, 

 or disappearing when taken out of the water. 



In the animals of this genus the gelatinous crust disappears almost entirely when 

 taken from the water, and is not like that of the Gorgonias persistent in the dried 

 state. The persistent spines in the Antipathes also serve to distinguish the two genera. 



A. spiralis. Lam. Simple, scabrous, long, subspiral. Inhabits In- 

 dian Ocean. Ellis, Zooph. pi. 19, fig. 1 6. 



A. cupressus, Lam. (Gorgonia abies, Lin.) Scabrous, somewhat 

 branching ; ramuli lateral, short, scattered, recurved, bipinnate. 

 Inhabits Indian Ocean. Ellis, Zooph. 103. 



Gen. 10. Isis, Lam. 



Fixed, of a tree-like form, composed of a jointed axis, and an 

 outer crust ; central axis branched, forming stony striated 

 articulations, horny between tbe joints ; crust containing poly- 

 pi in the fresh state, but fugacious and disappearing in whole 

 or in part when withdrawn from tbe water. 



I. hippuris, Lin. Slightly branched ; crust smooth, thick, with 

 many osculi ; joints of the axis stony, sulcated, irregular, the last 

 compressed; intervals horny. Inhabits Indian seas Ellis, Zooph. 

 pi. 3, fig. 15. Plate 8, fig. >], 8. 



I. dichotoma, Pall. Branched, filiform, jointed, diffuse; joints stony, 

 nearly smooth ; internodes narrow. A small species. Inhabits 

 Indian seas Petiv. Gaz. pi. 3, fig. 10. 



Gen. 11. MELIT^A, Lam. Isis, Lin. 



Fixed, in the form of a shrub, composed of a jointed knotty axis, 

 and a persistent crust ; central axis caulescent, branched, form- 

 ed of stony substriated joints, with the intervals spongy and
