AphanipatJies 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 niillim. (4^ in.) high, with a spread of 110 millim.

The specimen in the British Museum is 56 centim. (22f in.) 

 high, and is related to other flabellate forms included in the genus 

 ArdipatJiella. 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 irregidarly, the ultimate pinnules being very 

 slender and rarely attaining a length of 12 millim. without becoming 

 branched. Spines (Brook, Antip. Chall. pi. 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.)

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
