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

 1888, by Mr. George B. Sennett 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 they are L. 

 ludovicianus or the sub-species excubitorides, hence have deemed it best to include 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, ludovicianus exculritorides, should, 1 think, be 

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