Macgillivray 's Seaside Sparrow. — On September 5, Mr. F. M. Wes- 

 ton, Jr., took a specimen of an adult Macgillivray 's Seaside Spar- 

 row (Passerherbulus maritimus macgillivraii) . This is the first 

 record of the Natural History Society 's survey for this sub-species, 

 it not having been previously distinguished from the Seaside Spar- 

 row (P. maritimus). Several other specimens have since been 

 taken by Messers Rhett and Burnham Chamberlain, one on Sul- 

 livan's Island, and others on Plum Island, where they have been 

 abundant. Of these, two were birds of the year, one having the 

 tail feathers but partly developed. This sub-species may be dis- 

 tinguished from the Seaside Sparrow by the blackish mesial streak 

 on the central tail feathers. Mr. Weston has presented his speci- 

 men to the Museum and Master Rhett Chamberlain has given one 

 of the young birds taken by himself and his brother.
