lxiv Journal of Proceedings. and I have one of them yet—a very healthy bird, thanks to the care of Mrs. Travis. The boy had thrown away the nest, but described it as very much like a linnet's, but smaller. Mr. Harting said he should like to make a few remarks on the above list. Many of the birds mentioned were of extreme rarity, and he thought it would be wise to ask for further particulars before giving the list a permanent place in the records of the Club. From experience he could say that in many cases it would be found on examining the evidences on which such lists were based that the writers have been too hasty in identifying their specimens with rare species. The very first bird on the list, to his mind, was very doubtful; the Dusky Petrel was of extreme rarity in Britain, and has only been obtained on one or two occasions; he could not help thinking that the bird referred to would prove to be a specimen of the Manx Shearwater; that bird breeds here, and it is often called a Petrel, although it differs from that genus in some respects. Of course it was quite possible that all the birds mentioned were correctly named, but he would strongly urge the neces- sity of caution and enquiry before accepting as absolute facts the statements made in such lists as the above. The President thought all would agree with Mr. Harting in the necessity for caution : errors were easily committed and then became difficult to eradicate. He would suggest that the Secretary should communicate with Mr. Travis, with the view of settling the questions raised. [The list was returned to Mr. Travis, who, we understand, is a good ornithologist, and it is now printed as revised by him.—Ed.] Mr. P. Copland exhibited some specimens of fossil wood from the London clay at Walton-on-the-Naze, and Mrs, Yeates some glacial drift fossils picked up in the neighbourhood of High Beech.
