We are indebted to the Weather Report of the Meteoro-

 (L.) = Lantern. 



(O.H.) = Outer Hebrides.

 of uncommon visitors, which reflects favourably on the keen- 

 ness of Scottish observers. Important extensions of Scottish 

 breeding ranges are noted in the case of the Crested Tit 

 and Gannet, both being species whose breeding places in 

 these islands may be described as limited, and no extension

 the case of the Crested Tit, the spread was first noticed 

 several years ago, but the records have only now been 

 published.

 species arrived unusually early, while others were inclined
