104 THE ZOOLOGIST. 



backed Gull, Black-headed Gull, and Puffin. I had remarked 

 with surprise the absence of the Stonechat when I was on the 

 island. Mr. Coward saw a male in an excited state, and he felt 

 sure that there was a female and nest somewhere near. It is 

 common on the mainland. There were many Swifts about, but 

 the nesting-place (if any) was not found. They wheeled round 

 the mountain and high above the fields, but were not heard 

 screaming round the farms. Many Puffins were seen about in 

 the tideway close in-shore, and Mr. Coward suspected that some 

 were breeding, but could not find where. On the other hand, 

 they may have been fishing, and have belonged to the warrens 

 on Ynys Gwylan not far away. Had they been breeding, some 

 would most likely have been seen on the land at that date, or 

 coming into or leaving the cliff. The other three species were 

 probably stragglers. Mr. Coward also saw the Pied Wagtail 

 (which I believed I saw), an old and young ones hardly strong 

 enough to have flown from the mainland. But, on the other 

 hand, he did not see eleven of the species that I saw. Four of 

 these were probably stragglers, though it is possible the Common 

 Sandpiper may breed. But the other seven I found fairly well 

 established or represented, viz. Willow-Wren (a few), Spotted 

 Flycatcher (several about farm gardens), House-Martin (several, 

 but not breeding), Sand-Martin (a few), Goldfinch (a pair at 

 least, and I believe more), Chaffinch (fairly common), and 

 Cuckoo (several). And it is strange that they should have had 

 such a poor hold on the locality. It is hardly possible that 

 some of them at all events would be overlooked by so good an 

 observer. We neither of us saw any Skylarks, Bobins, Yellow 

 Buntings, or Wrens, though I feel sure the last-named must be 

 present. As Mr. Coward was there later in the season than I 

 was (May 23rd to 24th) he found the Bazorbill and Guillemot 

 deeper in the business of breeding, and reports at least a score 

 of pairs of the former, and at the same place (East-side) a long 

 line of Guillemots on whitewashed ledges, fifty or sixty pairs at 

 the lowest estimate, and he thinks more likely some hundreds. 

 The Peregrines were still in possession. He secured a few 

 Long-tailed Field Mice, a Common Shrew, and found the 

 Palmated Newt. 



I paid a very short visit to Lleyn in 1906 (May 29th to
