Antedon diibenii, (part) Gislen, Atlantide Rep., No. 3, 1955, pp. 84-91 {rnoroccana a synonym of dH 

 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 that in lateral view the cirri are nearly or quite twace as broad distaUy as pro.ximally; 

 the longer pro.\imal segments are from half again to tmce as long as the median width, 

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



Description. — Centrodorsal flattened hemispherical to almost discoidal, with a 

 rather large bare dorsal pole about 3 nmi. in diameter. (Sec p. 235, imder 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 t^dce 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.
