Cd varies in diameter between 1 and 2 mm. Cirri appearing in 

 one or two whorls. Cirrale 2 : L = 1 '/2 — 2 X br; Cirrale 3 : L = 272 — 

 3 X br; Cirrale 4 : L - 3V/2 X br; Cirrale 5 : L = 1 '/2 — 2 X br. 



This species is most closely related to C. decora A. H. Clark 

 from Japan but is separated from this species, by 1): the cirri, which
