Antedon diibenii, (part) Gisln, Atlantide Rep., No. 3, 1955, pp. 84-91 (moroccana a synonym of du- 

 benii), pi. 1, fig. 3 (cirri), pi. 2, fig. 7 (pinnules), pi. 3, figs. 10, 11. 



Diagnostic features. The outer cirrus segments are strongly compressed laterally, 

 so (hat in Intend view the cirri are nearly or quite twee as broad distally as proximally ; 

 the longer proximal segments are from half again to twice as long as the median width, 

 and the shorter distal segments are as long dorsally as broad proximally. 



Description. CYntrodorsal flattened hemispherical to almost discoidal, with a 

 rather large bare dorsal pole about 3 mm. in diameter. (See p. 235, under duebeni, 

 for notes on variation in the relative size of the dorsal pole.) 



Cirri XXIV-XXXV, 12-16 (usually 13-15), from 10 to 13 mm. long. In lateral 

 view the cirri are twice as broad distally as proximally, and the distal half is strongly 

 recurved. In the outer part of the cirri the segments are about as broad as long dorsally, 

 becoming terminally slightly longer, about one third again as long as broad. The 

 dorsal profile of the distal segments is perfectly straight, there being no trace of a 

 bidentate appearance. 



There is a conspicuous group of perisomic interradials in each interradius. 



The IBr series are very short and well separated laterally.
