Commenting on the fact that on November 26th, following, 

 an old bird was shot near Stirling, Herr Gatke writes : " There 

 can hardly be any doubt that both the latter examples left their 

 home at the same time and from similar motives, and that while 

 following the direction of their spring migration, the one got no 

 further than Heligoland, while the other by a less perilous route, 

 got so much further to the north west." 



The butterfly, Papilio podalirius, was observed on the same 

 day as the first named example, viz., June 23rd, 1880. " It too — 

 we are told — had probably been led beyond the limits of its home 

 and across the sea by the fine warm weather, and light south- 

 easterly and easterly winds." From this passage it appears, 

 it was these winds which induced the two Desert Chats to 

 perform their abnormal migration, not the loss of their mates. 



Eastern Pied Ghat. — A south-eastern species. One killed 

 May 9th, 1867 ; a second, June 6th, 1882. 



Galandra Lark. — ^Breeds throughout all the countries border- 

 ing the Mediterranean. An example said to have been shot by 

 Eeymers, June, 1839 or 1840. 



Black Lark. — A winter visitant to Southern Eussia, breeding 

 in Central Asia. A female, shot April 27th, 1874 ; a fine old 

 male subsequently shot, July 27th, 1892. 



Pallas' Short-toed Lark. — A resident in Southern Eussia. 

 One shot May 26, 1879. 



Short-toed Lark. — Breeds throughout the countries bordering 

 the Mediterranean. About thirty examples killed, partly in 

 spring and partly in autumn. The former examples on account 

 of their more ferruginous colour, compared with those which 

 have been shot in October and November, are said to un- 

 doubtedly have been derived from Greece and Asia Minor. 

 Herr Gatke remarks : " The home of the latter in Asia 

 must extend to the latitude of Heligoland, and the birds there 

 undoubtedly joining themselves to the many other species from 

 the far east, whose autumn migration proceeds in a westerly 

 direction. In the absence of one single actual instance in sup- 

 port of it, the idea of an autumn migration directed to the 

 north west from Greece or Asia Minor cannot be entertained" ! ! ! 

 Why not here more reasonably suggest that these autumn
