of the American Gos-Hawk being so unlike that of its Em'opeau 

 congener, besides remarking on some other points; but the 

 length of our article warns not to try further the patience of 

 our readers. 



We cannot, however, conclude without referring to the loss 

 we have recently experienced in the removal from among us 

 of one of the oldest, if not the very oldest, of British egg- 

 collectors. The frequenters of the meetings of the Linnsean and 

 Zoological Societies will henceforth look in vain for the kindly 

 smile and hearty greeting of John Drew Salmon, one of the 

 pioneers of oological discovery, and an active member of that 

 band of zealous working men which numbered in its ranks Hoy 

 and Heysham and Yarrell, besides others still happily spared to 

 us. Long may they continue to enjoy the results of their hard- 

 earned labours, and that they may be succeeded by a generation 

 as indefatigable as they themselves were, is, we are sure, as much 

 their wish as it is ours. Mr. Salmon, we are informed, has 

 bequeathed his valuable cabinet of eggs to the Linnean Society, 

 where we trust it will be preserved intact, as a monument to the 

 memory of a thoroughly single-minded man, and an example to 

 future naturalists of the care and discretion necessary in forming 

 an eminently trustworthy oological collection.

Both Stonechat and Whinchat are common in the oases as 

 winter visitants. The plumage of P. rubicola in the Sahara is 

 much richer in colour than in specimens obtained on the coast, 

 which are in their turn more brilliantly marked than the gene- 

 rality of our British specimens. I have had, through the kind- 

 ness of Sir W. Jardine, an opportunity of examining a series of 

 the South African species {Pratincola pastor, Strickland), and
