1. The Classification of the Copepods. 



By C. B. Wilson, Westlield, Mass. 



eingeg. 4. Februar 1910. 



Everyone who has studied the Copepods, Avhether free-swimming 

 or parasitic, must have been impressed with the great diversity of opinion 

 which has prevailed among investigators in regard to their classification. 

 On examining the different schemes proposed we find that not only has 

 every portion of the Copepod's body been used by one systematist or 

 another as a basis of classification, but even their habits, their mode of 

 life, and their method of reproduction have been called into service. 



And the men whose names we find attached to these various schemes 

 take rank among the foremost scientists of their time. 



We find Linnaeus (1735), for example, including the Copepods 

 (with other Crustacea) among the wingless insects, and dividing them 

 according to the number of appendages and the fusion of the head 

 and thorax. Fabricius (1775) in his revised editions of the Entomologia
