COLYMBIM. 
(bird-preserver). One shot on the Ouse, in the middle of York, 
a fortnight ago, and two at Acaster, a few days since. The 
irides of all three were of a dirty yellowish-white colour, and not 
red, as is usually stated.”* Those of the bird which came under 
my own examination were brownish-yellow, and those of the 
individual obtained in 1848 were noted as “ primrose-yellow.” 
This species has not been sufficiently numerous anywhere to 
become an object of the chase, like the great-crested grebe, but, 
like it, is most difficult to be “ run down ” on the water. Mr. 
Knox tells us that “ during March 1847, one of these birds 
having been observed for some time swimming and diving near 
the beach opposite Brunswick Terrace, Brighton, was pursued by 
a party of active rowers in a galley, and captured after a long 
chase.”f 
The red-necked grebe is of more frequent occurrence in Eng- 
land, and apparently in Scotland also, than it is in Ireland. 
A pair of these birds was shot by Captain May, on the 13th 
of July, 1849, on a swampy lake near the junction of the Salten 
river with the Eiord, in latitude 67°. This may be a breeding- 
haunt of the species. No others were seen by that gentleman on 
any part of the coast, rivers, or lakes of Norway.
