The young forms of the above-described species are very simi- 

 lai' to one another and probably cannot be distinguished h'om each 

 other. Presumably the two last-described species pass thi-ough a stage 

 with cirri built as in C. b) adujcirra. 



A comparison between the characteristics for the species descri- 

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