104 THE SCOTTISH NATURALIST 



pronounced rufescent brown of the British Tree-creeper 

 i^CertJiia familiaris britannica). It is a rare visitor to Scot- 

 land, the only place from which it has been recorded being 

 Fair Isle. 



The Continental Great Titmouse {Pants major 

 major) breeds in Europe and Western Siberia. It differs 

 from our native bird in having a slimmer, less powerful 

 bill. Specimens of this form have been obtained on the 

 Isle of May and in Shetland. It doubtless occurs elsewhere 

 down our coasts, but these are the only localities from which 

 it is authentically recorded. In the autumn of 1914 there 

 was a regular immigration of Continental Great Tits into 

 Shetland, where they remained all winter. The CONTI- 

 NENTAL Blue Titmouse {Pa?-us ccsruleus cccrukus) differs 

 from our British bird in being brighter and more yellowish 

 on the back, in being larger, and having a comparatively 

 slimmer bill. It breeds in Europe generally, and has only 

 once been recorded in Scotland, namely, in Peeblesshire in 

 September 1895. Two specimens of the CONTINENTAL 

 Coal Titmouse {Panis ater ater) are recorded in the new 

 B.O.U. list from Morayshire. It breeds in Europe and 

 Northern Asia, and differs from our resident race {P. a. 

 britannicus) in the grey tone of the upper side (washed with 

 yellowish olive in the British bird) and in having a some- 

 what longer wing. 



In the new B.O.U. Hand-list the BRITISH GOLDEN- 

 CRESTED Wren is not separated from the Continental, 

 However, as Dr Hartert has done so, and as the Goldcrests 

 from the Continent, as well as those obtained during the 

 large continental immigrations, appear to us to differ from 

 the British Goldcrest {Regulus regulus angloruin), we intend 

 to include it here. The CONTINENTAL GOLDCREST {Regulus 

 regulus regulus) breeds in Europe generally, east to the 

 Caucasus and Asia Minor. It differs from our bird in being 

 greener (less olive) on the upper side, this difference being 

 specially noticeable on nape and rump, rather lighter and 

 less brownish on the under side and sides of neck. Immigra- 

 tions of this form occur almost every autumn in greater 

 or lesser numbers on the Isle of May and in Orkney and
