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



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.
