CORDEAUX : MACQUEEN'S BUSTARD IN EAST YORKSHIRE. 323 



following species : — Closterium striolatum (showing very clearly the 

 phenomena of cyclosis and so-called Swarming of the granules' 

 at its extremities), Pediastrum granulatum, Cos murium botryiis, 

 while among the less common of the filamentous algoe, I was 

 fortunate enough to find in the Roche Abbey Lake, and sub- 

 sequently to be able to mount in its own water a well defined 

 gathering of Oscillaria spiralis, the curious and unexplained 

 movements of which (as of a headless screw turning continually on 

 its end) were extremely interesting to watch; 



Several other and more common species of Oscillaria and at 

 least three species of Spirogyra and Zygnema were abundant in the 

 Lake. 



OCCURRENCE OF MACQUEEN'S BUSTARD 



IN EAST YORKSHIRE,

On October 17th a remarkably fine example of this Eastern Bustard 

 {Otis macquteni J. E. Gray), a resident in the Aralo-Caspian region, 

 was seen in a vetch-stubble behind the warren house at Kilnsea. 

 It was shot at by Colonel White and flew off apparently uninjured. 

 On the next day it was killed by Mr. G. E. Clubley, of Kilnsea, in 

 a wheat-stubble in Easington. 



Mr. W. Eagle Clarke, who was out for a walk with Mr. Harry F. 

 Witherby, was fortunate in being able to watch the bird for a quarter 

 of an hour, at the distance of 150 yards, through a powerful 

 binocular. He says it looked on the wing very much like a large 

 owl, and flew low and slow, just skimming the ground. It was 

 pursued by small birds, and the Grey Crows hovered over it, marking 

 the place where it alighted, beyond a high bank. Its colour on the 

 w ing appeared isabelline and very contrasting black and white in 

 * T ing. In walking it carried its head and neck like a feedin 

 pheasant, moving in a stately fashion, but not with head erect The 

 tong black feathers on the side of the neck were conspicuous. 

 When first fired at it rose and flew very leisurely 100 yards and 

 alighted. When under observation it was either feeding or washing 



and preening itself. 



Mr. H. B. Hewetson, of Leeds, and myself saw the bird a few 

 minutes after it was killed, when I took the following notes: 

 Length, 28 J inches; flexure, 16; tarsi, 4$; iris very light-straw 

 yellow ; tarsi and feet nearly the ime colour, perhaps a trifle
