confusing. Young individuals of C. belli are very similar superficially to species of 

 Comaster, and the smaller they are the greater is this similarity. 



KEY TO THE SPECIES IN THE GENUS COMANTHINA 



a 1 . Proximal and middle pinnules with the segments in their basal portion produced dorsally into 

 conspicuous dorsal processes which on the lower segments may be as high as the width of 

 the segments themselves; cirri almost always present; distal cirrus segments with the distal 

 dorsal edge slightly produced and with a dorsal carination or pointed dorsal tubercle (coast 

 of Australia from the Abrolhos Islands northward and eastward to Torres Straits; 0-119 

 meters) belli, p. 458. 



a 1 . No dorsal processes on the basal segments of the earlier pinnules; cirri rarely present; if present, 

 the distal segments are entirely smooth dorsally (Maldive Islands and Ceylon to northern 

 Australia, the Solomon, Caroline, and Philippine Islands, and Macclesfield Bank; 0-278 

 meters) schlegelii, p. 466.
