382 THE ZOOLOGIST. 



river at some distance from the beach, and on the following day 

 saw a dozen feeding in a field near Llyn Penrhyn ; I followed 

 these birds as they slowly worked their way across the common 

 in the direction of Ehos Neigr ; no doubt they were some of the 

 same party. Until the 28th the numbers remained about the 

 same, though at times the birds were scattered over the warren 

 at some distance from their usual haunt ; at other times they 

 rambled over the rocks, sand, and shingle in the immediate 

 neighbourhood of the village. By the 28th their numbers had 

 gradually increased ; I estimated that there were at least thirty 

 or forty birds, but two days later I could only see a dozen.. 

 Possibly, however, some of the birds may have been feeding 

 elsewhere. On the morning of May 2nd, the day when Willow 

 Wrens were so abundant, I found that fresh birds had arrived ; 

 there were at least sixty in the usual] spot. Two days later 

 I came across four on the north shore of the island at Cemllyn. 

 Towards the 12th the N.W. or W. wind got round to the N., and 

 later, on the 18th and 14th, was easterly ; on the 14th I could 

 only find about a dozen birds, and four days later — easterly 

 winds still prevailing — their numbers were further reduced to 

 four or six. These few birds — I took them to be laggards — 

 remained for ten or twelve days longer. On the 30th I could 

 not find any about, and a single bird on June 2nd was the last 

 I saw. Some of the hens had very little, if any, black upon the 

 crown. Mr. 0. V. Aplin, who saw the remnant of the birds, 

 suggested that as they remained so late they were probably 

 Arctic and not Continental birds. In the evening the birds 

 roosted in the Maelog reeds at a short distance from their usual 

 feeding ground. 



Gkey Wagtail. — On two occasions I saw the Grey Wagtail 

 on the Cefni at Llangefni, and on June 12th saw a pair with 

 young on a small stream at Coed Cadwr. 



Yellow Wagtail. — The Yellow Wagtail does not appear to 

 breed in Anglesea ; we have kept a sharp look out for it every 

 spring when we have visited the island. It does, however, 

 occasionally pass on migration. On April 18th a male was 

 feeding on the marsh near Ehos Neigr, and a male and female 

 were with a few of the White Wagtails on the warren near Llyn 

 Maelog. On April 21st a male was feeding with the White
