NOTES ON THE NORTH AMERICAN LITHOBIIDiE AND SCUTI- 



GERIDiE. 



ByCIIARLE!^ II. BOLL-MAN. 



lu examining the collection of myriapods belonging to the museum 

 of the Indiana University, I have found a number of species new to 

 science. On account of the confused condition of our North American 

 myriopoda, I have deemed it best to introduce a description of the known 

 species embraced in the same collection, as well as the description of 

 those species supposed to be new to science. 



The types of the new species have been deposited in the United 

 States National Museum.
