of freshwater lakes, but none of them so high in the mountainous districts as he expected to

 three in number, are deposited early in May, and that the young when hatched are very plenti- 

 fully supplied with food by their parents. 



Eggs of the Iceland Falcon in my collection vary exceedingly ; the ordinary run of the series 

 I possess are pale yellowish clay-white, so closely marked with reddish orange as almost to appear 

 uniform reddish orange in colour; some, however, are white, somewhat sparingly blotched all 

 over with reddish orange ; some are more profusely blotched with dull (almost chestnut) red ; and 

 one is almost uniform dull rufous clay-coloured. In size they vary from 2^ by lf-jy and 2^f by 

 Iff inch to 2^§ by Iff inch. 



The specimens figured are an adult bird on the one Plate and a young bird on the other 

 Plate, both being those above described. 



In the preparation of the above article I have examined the following specimens : —
