 4 — Ü oblique articulations. The outer margins of the distal segments 

 very much bent outward and finely spinous.

The young forms of the above-desei'ibed species are very simi- 

 lar to one another and probably cannot be distinguished from each 

 other. Pi-esumably the two last-described species pass through a stage 

 with cirri built as in C bradmcirra. 



A comparison between the characteristics for the species descri- 

 bed above also shows that C. maculata comes near to C. stelligera and
