t Thirteen Shrikes or Butcher-birds, as they are commonly called, were taken, August 5 and 6, 

 1888, by Mr. George B. Sennctt and myself in Erie county. The specimens were adults and young 

 of the year. Owing to the bad plumage of these birds I am unable to say whether thcj' are L. 

 ludoviciamis or the sub-sjjccics excuhltoridex, hence have deemed it best to mclude both in this 

 list as summer residents. These birds are said to be equally as plentiful in Crawford county as 

 they are in Erie during the summer season. L. \iidovicianu» exciihilorides, should, 1 think, be 

 eliminated from the A. O. U. Check List.
