Diagnostic features. Except for having the cirri wholly confined to the inter- 

 radial angles of the centrodorsal, one or two being present in each interradius, this 

 species agrees with C. pectinata. It differs from C. tenuicirra, in which the cirri are 

 similarly segregated in the interradial angles, in having the longest cirrus segments 

 little, if at all, longer than broad.
