ter, and two or tJiroe foet in length, piled to the height of 

 four or five feet, and from two to three feet in breadth ; these 

 were intermixed with corn-stalks, sea-weed, pieces of wet 

 turf, in large quantities, and lined with dry sea-grass ; the 

 whole forming a mass observable at half a mile's distance, 

 and large enough to fill a cart. About the first of May, the 

 female begins to lay her eggs, which are commonly three in 

 number, sometimes only two, rarely four."' — Fig. 1. 



FALCO ISLANDICUS. (latiiam.) 

 Gyr Falcon. 



Two eggs of this rare bird are in the collection of Mr. 

 Yarrell, by whom they have been kindly forwarded to me. 

 They are the only specimens I have heard of, with the 

 exception of one in the museum at Leyden, a drawing of 

 which was, with the greatest kindness, sent me by Professor 

 Temminck, through the instrumentality of Mr. Hoy. 



The Jer Falcon breeds in rocks, in those countries, which 

 are rendered difficult of access, from the severity of their 

 climate. 



We were not so fortunate as to meet with it in Norway, 

 although w^e were told, that had our time permitted, w'e might 

 have done so, by penetrating, for some days' journey, into 

 that part of the country which was covered with snow.
