224 Bulletin No. 7. 



closed in brackets is to be regarded as a casual or accidental 

 visitor only, or so rare as to render it practically an extraneous 

 element of the fauna. The annotations are intended as merely a 

 brief indication of the manner of occurrence of the species, par- 

 ticularly as regards season and relative abundance. The records 

 of capture of the rare or accidental visitors are fully given for 

 the last ten years, and generally for the last twenty years, or for 

 the interval since the publication of my first Catalogue in 1864. 

 The earlier records are generally omitted, but they were included 

 in the 1864 list. These three lists 1864, 1878, and the present 

 with the "Notes" published in 1870, give a nearly exhaustive 

 record of the occurrences of the rarer birds of the State. As a 

 matter of correlative interest, reference is also made, in most such 

 cases, to records of capture in adjoining States, as tending to 

 indicate the probable status of the species as a Massachusetts 

 bird. With few exceptions only the original record is cited.
