246 BRITISH BIRDS. 



Suffolk; probably also with this migration came some Blue- 

 throats, but they (two) were not detected till the 16th. These 

 Robins were seen up till the 16th, after which there were none 

 till November 1st, when a few more had arrived with large 

 numbers of the Continental Song-Thrush [Turdus m. musicus) ; 

 in a day or so these had gone. From about October 28th 

 to November 4th Robins were said to be plentiful in the gardens 

 on the Yarmouth Denes, Norfolk, and specimens which I 

 examined belonged to the continental form. In the field 

 the paleness of the breast of this form, as compared with our 

 birds, is quite noticeable, if one is fortunate enough to see its 

 breast, for it is one of the most skulking and shy birds when seen 

 on our coast — very different in habit from the resident Robins 

 seen in the same spot. 



During the last fortnight of October there were four days 

 on which there were arrivals of Song-Thrushes, culminating 

 in a big rush on November 1st. The great majority of these 

 birds belonged to the continental form, and all those which 

 I saw on the last day certainly did. They remained on the 

 coast only a day or two. Here, again, this form is distinguish- 

 able in the field, to the practised eye, from our form by the 

 more olivaceous coloured upper-parts. 



Although both the Continental Robin and Song-Thrush 

 doubtless occur on the coast of East Anglia every autumn, 

 and probably have been obtained before, I do not think that 

 there has been any previous definite record of the fact. 



The advantage of studying and recognising geographical 

 forms in connection with migration will, I think, be obvious 

 to the greatest sceptic. C. B. Ticehurst, 



In connection with Dr. Ticehurst's note I must record 

 that I obtained specimens of Erithacus r. rubecula between 

 September 21st and 25th, 1905, at Holkham, near Wells, 

 Norfolk ; on October 27th, 1909, on the south Yorkshire 

 coast ; and on April 1st, 1906, from St. Catherine's Light- 

 house, Isle of Wight, while two were taken at the same light 

 on the night of October 23rd, 1908, and many were reported 

 with British Robins on the night of October 31st, 1908, and 

 a few of the continental race only on November 3rd {Bull. 

 B.O.C., Vol. XXVI. (Mig. Rep.), p. 237). I have also identified 

 a specimen in Mr. G. H. Caton Haigh's collection, dated 

 North Cotes, Lincolnshire, October 6th, 1898. Of Turdus m. 

 musicus, I have specimens from Holkham, obtained on 

 September 23rd, 1905, from the south Yorkshire coast on 

 September 22nd, 1909 ; and from St. Catherine's Lighthouse 

 on April 22nd and 28th, 1906, and have examined a specimen 

 in Mr. Caton Haigh's collection dated October 19th, 1892,
