FULIGULA FULIGULA. 245 



My own eggs varied a good deal more than these, as my largest is 

 2*46 X 1*68 inches, and my smallest 2"15x 1*50. 



Finn^s remark on the cross-breeding of this bird is worth notins; and 

 remembering by sportsmen who get hold of birds beyond their power to 

 discriminate : — 



" It breeds more freely in captivity than do Pochards in general, and 

 in the London Zoological Gardens crossed in 1849 with the White- eye, the 

 resulting hybrids continuing to breed either inter se or with the original 

 parents for more than ten years — a fact to be remembered in dealing with 

 doubtful Pochards, which should therefore, whenever possible, be submitted 

 to some authority for identification/'
