The collections of lice discussed in this paper were made in Myerstown, 
Lebanon County, Pennsylvania, and vicinity. All birds as will be seen, are 
migratory birds except one, the English sparrow. 
A list of species found on a number of birds is given herewith. There was 
absolutely no straggling of lice from one bird to another as might be the case 
if the birds were placed in one bag. These lice were collected in the field, 
that is, as soon as the bird was procured, they were picked and preserved in 
vials of alcohol. Consequently, there was no danger of migration of parasites 
from one bird to another.
