the syzygy in the third brachial of the primary arm, and they may therefore be 

 considered as members of the ten-armed series. 



The terminal cirrus-joints of Antedon variipinna are more sharply carinate than 

 those of Antedon anceps (PI. XXXV. fig. 3; PI. XXXVI. fig. 1), and are sometimes 

 spinous, while the interval between the later syzygies of the arms is considerably longer 

 (PL XXXV. fig. 2; PL XXXVI. fig. 3). Furthermore the joints of the third pinnule 

 have more or less prominent lateral processes, while those of Antedon anceps are smooth 

 (PL XXXV. fig. 2 ; PL XXXVI. figs. 1, 4).

Centro-dorsal a thick, roughly circular disk, with the dorsal surface bare, and 

 bearing from twenty to thirty marginal cirri. These have from twenty to thirty 

 stout joints, all wider than long, the basal ones especially so. The penultimate joint 

 sometimes, but rarely, has a small opposing spine.
