named month, during May, and the first week in June, 

 that it occurs in some numbers. 



In autumn it has appeared as early as 13th July, 

 and as late as 2nd November, being most abundant and 

 frequent during August and September. 



ToTANUS NEBULARius, Greenshank. — Until the year 

 1 9 10, there was 'only a single record of a solitary 

 example, which appeared on 21st August 1908. In 

 1910, one was seen on 30th August, and on ist

 shot in a moist place amid the crofts on 8th January 

 1908. The occurrence of this species in Scotland in 

 winter has hitherto been unknown, and to find it 

 as far north as Fair Isle, at that season, is certainly

 days of February, but early March is the ordinary date 

 for the first visits of the season. The passages are in 

 progress until late in May, and sometimes early June, 

 and considerable numbers have been observed in rushes 

 with other migrants. 



A few appear in July, many in August, and varying
