MYRIAPODA MUSEI CANTABRIGENSIS, Mass. 



Part I. Chilopoda. 



By Fr. Meinert, Copenhagen. 

 {Read before the American Philosophical Society, Octobers, 1SS5.) 



Several years since Mr. Alexander Agassiz, the director of the 

 Museum of Comparative Zoology, Cambridge, Mass., through 

 Dr. Hermann A. Hagen, offered to place in my hands the Myria- 

 poda of that museum for examination and description. It was 

 thought necessary at the same time to include the Myriapoda of 

 the Museum of the University of Copenhagen, by which the 

 work certainly gained as to completeness, but was on the other 

 hand not a little delayed. When my report on the first part of 

 the Myriapoda, the Chilopoda, was so far advanced that prepara- 

 tions for the press had to be commenced, there arose some diffi- 

 culty as to a joint publication. I shall therefore begin with the 

 Chilopoda of the Cambridge Museum, while the report upon that 

 class in the Copenhagen Museum will appear in the " Katur- 

 historisk Tidsskrift," in which the greater part of my previous 

 papers on the Myriapoda are to be found. 



In the years 1866-1872, I treated both groups of Myriapoda 

 in a series of essays, in all of which, in regard to the parts of 

 the mouth, I accepted Savigny's explanation and used terms 

 agreeing with it. Subsequently m}^ studies of the different classes 

 of the Arthropoda raised doubts in my mind as to the correctness 

 and propriety of these explanations. •Thus I was led to examine 

 the foundation of the whole view of the subject, and when neither 

 Savigny nor any of his school appeared to me to have taken the
