Genus COMISSIA. 



Comissia 1909. A. H. Clark, Proc. U. S. Nat. Mus., vol. 36, p. 501 (Clomissia 

 liitkeni, sp. nov.). 



COMISSIA PEREGRINA. 



Actinometra peregrina 1894. Bell, P. Z. S., 1894, p. 402. 



Habitat.— Macclesfield Bank . 



Depth.— 55-60 fathoms. 



Remarks.- The cirri are XII, 25-30 (usually nearer the latter), 20 mm. long ; 

 the fifth is a transition segment. 



The mouth and the anal tube are equally excentric. 



The ten arms are 120 mm. long, resembling those of Comissia Mkeni ; 

 the synarthrial tubercles are only slightly evident ; the distal edges of the 

 brachials are moderately produced. The distal intersyzygial interval is three 

 oblique muscular articulations. 



This species appears to be nearest to G. liitkeni, but is readily distinguished 

 by the more numerous cirrus segments.
