Show 1899.] ANTIPATHARIAN CORALS OF MADEIRA. 821 Aphanipathes wollastoni. Others have been discovered seated on the telegraph-cable when hauled up for repairs from a considerable depth. The figure shows one of these, a small but characteristic specimen, only 106 millim. (4£ in.) high, with a spread of 110 millim. (4f in.). Hab. Madeira. [ANTIPATHELLA BROOKI, nom. nov. Antipathella ? gracilis, Brook, Antipatharia of the ' Challenger,' p. 113, non Grav. The specimen in the British Museum is 56 centim. (22| in.) high, and is related to other flabellate forms included in the genus Antipathella. The base consists of several stems fused together, which give rise to a series of branches not all in the same plane, with frequent fusions. Upper portion more spreading, but the larger branches are still strong and are often fused together. In some portions nearly all the branches come off from one side and are placed at irregular intervals. Secondary branches mostly very slender. Medium branches bear branchlets irregularly varying in length from 15 to 100 millim., usually longer on one side than the other. Smaller branchlets simple and filiform : the larger ones are again branched irregularly, the ultimate pinnules being very slender and rarely attaining a length of 12 millim. without becoming branched. Spines (Brook, Antip. Chall. pl. xi. f. 8) short and conical with a slender apex, arranged in dextrorse spirals. Five rows are visible from one aspect of a pinnule, the members of a row being from two to three lengths apart. (Brook, loc. cit.) Hab. West Indies (Scrivener).'] Gen. APHANIPATHES Brook. Corallum paniculate or flabellate; spines long and slender; polyps obscure, with short tentacles. APHANIPATHES WOLLASTONI Brook. Aphanipathes wollastoni, Brook, Antipatharia of the ' Challenger,' p. 126. Antipathes subpinnata Gray (non Ellis & Sol.), P. Z. S. 1857, p. 293. Colour dark brown. Bushy, shrub-like, branched to the fourth or fifth degree of subdivision. The secondary branches elongate, often reaching to the top of the bush. Ultimate branches very numerous, very slender and varying considerably in length. They and the penultimate branches are thickly set with spines which are arranged in six or seven longitudinal rows as well as in irregular spirals. The simple, tapering, acute spines rise from a broad thick base and are directed obliquely forwards. The polyps are seated on the upper side of the branchlets in a single row at a distance from each other. Six short, thick, conical |
