THE MILLIPEDS OF CENTRAL AMERICA. 



By Ralph V. Chamberlin, 

 Of the Museum of Comparative Zoology, Cambridge, Massachusetts. 



This paper, like its predecessor on the centipeds of the same 

 region, is primarily a report upon the material of the group ex- 

 isting in the collections of the United States National Museum, col- 

 lections which have been enriched especially by the contributions of 

 Drs. O. F. Cook and W. M. Mann. The collection of the Museum of 

 Comparative Zoology has also been reviewed. In addition to the 

 forms studied in these collections, it has been the intention to include 

 all other species thus far described from Panama, Costa Rica, Nica- 

 ragua, Salvador, Honduras, British Honduras, and Guatemala. 



The forms now known to occur are listed separately for the 

 several countries below.
