NOTES ON THE NORTH AMERICAN LITHOBIID^E AND SCUTI- 



GERID^E. 



BY CHARLES H. BOLLMAN. 



In 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 descrip- 

 tion of those species supposed to be new to science. 



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

 States National Museum.
