APPENDIX : NOS. XLV.—XLVI. 69 
the month of September, goimg up the Guadalquivir in a steam-boat 
to Seville, I saw several flocks of the Great Bustard at no great 
distance from the river banks, on the level, and at that time of the 
year burnt up, plains which extend, almost without trees or enclosure, 
on each side of the Guadalquivir. These flocks consisted, as I 
remember, of four or five birds each; and from the deck of the vessel, 
which was almost on a level with the land, they appeared to be 
walking in file, some with their heads down, and reminding one of 
Gilbert White’s note, ‘ Bustards upon the downs look like deer in 
the distance.’ This appearance of walking in a row was probably 
deceptive. ‘There was nothing in their manner to give the impression 
that they were timid, or very cautious, but one at least of a party 
frequently had its head raised as the steamer passed at a few hundred 
yards’ distance, and with the help of my glass I thought this was 
generally a cock bird. On one occasion, as the boat came suddenly 
round a corner several of them rose together from the edge of the 
water, springing hastily to the height of forty or fifty feet, nearly 
perpendicularly, partly perhaps to clear the bank, and then turning 
suddenly and somewhat clumsily, and after a few more not rapid 
strokes, sailing along with the arched form of wing so general in 
game birds. 
“T have now told you all I know about the Great Bustard in - 
Spain. I wish I had more to say about it. I was told that the 
Spanish name was Adbutarda, which is, I should imagine, connected 
in some way with the specific name ‘ tarda,’ for the bird can hardly be 
called ‘slow,’ but I do not know who gave it its scientific appella- 
tion. On the occasion I have referred to, a Spaniard on board the 
steamer told me that two or three months earlier in the year was 
the time for shooting the bird, and that then they were not difficult to 
approach with the assistance of cattle or carts, if I remember night. 
This would of course be in the breeding season.”’

Tue notice of the supposed occurrence of the Rufous Swallow

not any longer to delay recording in your pages, the supposed 
appearance of an individual of an American species of Swallow at

the Zoological Society on the 28th of February, 1860, as recorded in its ‘Proceedings
