it up, I remember that its grey back at once struck me, so 

 that I took it with me and liad it skinned. 



The colour o£ the underside of my Dutch birds varies 

 considerably : in some it is light, even whitish, on the 

 abdomen, in others it is dark, and one or two liave the under- 

 parts nearly uniformly dull vinaceous, with only a slightly 

 lighter shade in the middle. One of these more sombre- 

 coloured birds has a semicircular collar of black blotches 

 across the throat. These dark patches are to be found on the 

 throats of a few other birds, but less defined and much lighter, 

 and they are, according to Dr. Hartert, mostly to be found 

 on true G. <j. glandarius and seldom on G. g. rufitergum. 



So my series of Jays collected in Holland may be said to 

 be a kind of mixture of the two forms. This is^ however, 

 not to be wondered at, as all my birds have been collected 

 during the winter half-year when, of course, a large influx 

 of migratory birds may be expected. That our country 

 should be visited by great quantities of Jays from the north- 

 east on migration is natural, but the question was whether 

 Holland is also visited by British birds. In order to 

 ascertain this as far as possible, I requested one of my 

 correspondents in London to send me some English skins, 

 and in compliance this gentleman sent me two specimens, 

 from Montgomeryshire and Kent respectively. These I com- 

 pared with my birds, and found some of the latter exactly 

 like the two British Jays. So, in all probability, some birds 

 migrate from England to Holland, and maybe go farther 

 still. The same has been proved, by means of ringing, for 

 other species, e. //., the Redbreast. 



Some time ago I received for examination, by the courtesy 

 of Count Gyldenstolpe, four Jays from the Natural 

 History Museum at Stockholm. These birds were col- 

 lected near Uppsala (east Sweden) between 23 October 

 and 23 January, and are all undoubted G. [/. ylandarius, 

 although collected during the winter. Count Gyldenstolpe 

 at the same time informed me that the Museum un- 

 fortunately does not possess any obtained during the 

 breeding- season, but that there are some mounted birds
