308 TEN YEARS IN SWEDEN. 



Bree observes "We have the two birds the same size,, 

 colour, and form, but they may be distinguished by the fol- 

 lowing characters : In Sylvia hippolais (the Scandinavian 

 bird) the wing in repose does not reach half way to the 

 tail, and the first primary is equal, or nearly equal, to the 

 fifth ; in 8. icterina the wing is always longer by two-fifths 

 of an inch or more, than that of 8. hippolais, and it conse- 

 quently reaches beyond the middle of the tail, and the first 

 primary is equal in length to the third ; and these distinc- 

 tions are constant both in male and female." 



Whatever confusion has existed in the synonymes of 

 these two birds, " and this has not been slight/' it seems 

 clear that the Swedish ' ' Bastard Naktergal " is the true 

 Motacilla hippolais of Linnaeus.
