96. British Association' s ' Report on the Migration of 

 Birds.' 



[Report oil the Migration of Birds in the Spring and Autumn of 1887. 

 By J. A. Harvie-Brown, J. Cordeaux, R. M. Barrington, A, G. More, 

 and W. Eagle Clarke. Ninth Report (Vol. ii. no. 4). Svo. Edin- 

 bui^h: 1889.] 



This is the ninth and final Report of a Committee which 

 has done excellent service, although it has received an infini- 

 tesimal amount of pecuniary assistance and ver}' little 

 encouragement from the public. The patient labours of the 

 individual members have now ceased, but the impetus given 

 to the system and habit of taking an intelligent interest in 

 our migratory birds will long continue among the light- 

 keepers and others^ who have responded so actively to the 

 appeals made by the various recorders. We are glad to see 

 that Mr. W. Eagle Clarke is condensing the lesults of the 

 investigations made during the past nine years. The Red- 

 breast(d Flycatcher [Muscicapa pai'va) and the Lapland 

 Bunting {Calcarius lapponicus) have been added the Irish 

 list. Special thanks are due to Messrs. R. M. Barrington 

 and A. G. More for the clear manner in which they have 

 presented their portion of the Report.
