and Essex. During tlie first week of May the birds con- 

 tinued to arrive, though in diminishing numbers, and passed 

 steadily northwards. This large straggling immigration, 

 which, judging from the wings procured at the lighthouses, 

 lasted for nearly three weeks, consisted of both the larger aud 

 smaller races, the former predominating. 



The seventh and last immigration, which consisted entirely 

 of birds of the larger race, was recorded from the Devon 

 lights on the 27th5 28th, and 31st of May, but the course 

 the birds took after arrival could not be traced. 



It may be noted that with the exception of one solitary 

 example procured on the 1st of April, none of the larger race 

 arrived until the fifth immigration between the 9th and 13th 

 of that month, and with a similar exception of a single bird 

 obtained on the 4th of May, none of the smaller race arrived 

 after the end of April. 



Note. — The long and straggling sixth imnaigration, lasting in suc- 

 cessive waves from April IStti to May 6th, has for the sake of 

 clearness been omitted from the map. Its course differed in 

 no respect from that of the previous immigrations.
