THE HOUSE-MARTIN. 



Chelidon urhica (L.). 



The first arrival of this species was recorded in Hampshire 

 on the 30th of March, and on the 1st of April two House- 

 Mar fins were noted in Cornwall, one in Somerset and ten or 

 twelve " on passaoe " in the Isle of Man. 



During the first week of the month straoglers were 

 reported in Dorset, Surrey, Herts, Radnor, Warwick and 

 Lancashire. On the 13th of April "many," apparently fresh

 they were noted at the Devon lights, and during the next few 

 days were observed on pas^sage in Shropshire, Staffordshire, 

 Lancashire and the Isle of Man. 



The first records from the east were a few seen in Kent on

 Isle of Wight ; on the latter date there was an increase

 increase in Norfolk on the following day. From April the 

 29th to May the 5th numbers coming from the south-east and 

 " going inland " were recorded from Yorkshire, and on the 

 former date numbers were noted in Shropshire. On the 6th 

 there seems to have been a great increase in Yorkshire.
