a very peculiar butterfly-like flight to the lower end of 

 another crevice in the rock. I never saw one of them 

 progress head downwards or sideways, and the only 

 sound that I heard from them was a rapidly repeated 

 single note somewhat resembling that of the Wryneck. 



In the winter months the Wall-Creeper may often be 

 met with on old buildings and in gorges near the sea in 

 Southern France and along the Italian Riviera ; I have 

 known of its occurrence at that season within a very 

 short distance of Toulon, in the towns of Nice, Mentone, 

 Albenga, and Genoa. I once had the offer of one of 

 these birds alive from a London dealer, but, as the price 

 was excessive and the bird in Switzerland, I declined to 

 run the risk. With regard to the occurrence of this 

 species in England, I consider that the chances of 

 escape from captivity are in these instances so infini- 

 tesimal that the bird is fairly entitled to rank in our 

 British list.
