niiorations we paid special attention. Of the interior of the 

 island I can say but little, as I did not traverse it very 

 much. The greater part of it appeared to be grass and agri- 

 cultural land, intersected with innumerable dykes, and here 

 and there a few plantations ; the polders or more recently 

 reclaimed land I need not describe, as they are well 

 known. 



A good many of the resident species of birds did not 

 come under observation, as we very seldom, if ever, visited 

 suitable localities for them, while some of the summer 

 visitors had apparently departed before our visit. 



If every record is accepted, the number of species which 

 breed on Texel is 101. Of these, four — the Cormorant, 

 White Stork, Spoonbill, and Common Gull — undoubtedly 

 used to breed, but have now gone ; while ten — the Marsh-Tit, 

 Groldfinch, Great Grey Shrike, Stone Curlew, Little Owl, 

 Barn Owl, Goshawk, Pochard, Widgeon, and Great Black- 

 backed Gull — rest on Thijsse's authority only. Possibly 

 some are included erroneously and others were but single 

 instances (in which category the Woodchat may also be put), 

 as no one, so far as I am aware, has met with them since. 

 Of one — the Pintail — there is a certain amount of evidence 

 to show that it was introduced. In addition to these, it is 

 probable that three more breed, or have bred — Stock Dove, 

 Nightingale, Stonechat — according to Mr. Vaughan, who 

 also is the sole authority for the occurrence of the Purple 

 Heron and Short-toed LarK. 



Concerning one or two other species information does not 

 seem very certain. The total number of birds noted for 

 Texel in this paper is 144, but of course there are many 

 others which I was informed occur on migration and doubt- 

 less do so, such as the Shore-Lark, Snow-Bunting, Bluethroat, 

 Peregrine, &c. 



Song-Thrush.

 Oosterend and an odd bird in the village. First arrivals on
