rays which may have been Eobins. The numbers of birds 

 round the lantern this night were not many, and their presence 

 was of short duration. The first bird I saw was at 8 p.m., the 

 last at 10.30 p.m. The weather was calm, the sky dark and 

 overcast, but the atmosphere was clear, and a light breeze was 

 blowing from the north-west. 



The occurrences of the Eobin, then, which took place during 

 my residence on the Tuskar Light- Station may be summed up 

 as follows : — 



First visit, Sept. 11th to Oct. 7th, 1911. 

 Sept. 12th. — One Eobin seen on the Eock, 7.40 a.m. 

 Sept. 17th. —Two Eobins collected at the lantern at 9 p.m. 

 [A few others suspected to be Eobins, seen in the rays.] 

 Total number of records : three. 

 Second visit, March 21st to April 22nd, 1912. 



No occurrences recorded. 

 Third visit, July 29th to Sept. 30th, 1912. 

 Aug. 15th. — Two Eobins collected at the lantern — the first at 



10.40, the second at 11.10 p.m. 

 Sept. 12th. — One Eobin collected at the lantern at 10.10 p.m. 

 Sept. 14th. — One Eobin collected on the Eock at 9.30 a.m. 

 [Another, suspected to be a Eobin, seen in the rays of the 

 lantern at 8.2 p.m.] 

 Sept. 16th. — One Eobin collected at the lantern at 



11.35 p.m. 

 Total number of records : Jive. 

 Grand total made during one hundred and twenty-four days' 



residence at the Tuskar Light-Station : eight. 

 N.B. — Occurrences included in square brackets, whose identi- 

 fication is uncertain, are excluded from the numbers in this 

 summarized list. 



Before concluding this paper, I should like to refer to the 

 extraordinarily small number of Eobins which Mr. Barrington 

 actually received during his negotiations with all the light- 

 keepers round the Irish coast during the period of years 

 extending from 1881 to 1897. Only two specimens were 

 received — one in spring (killed striking the Blackwater-Bank 

 Lightship lantern, Co. Wexford, March 13th, 1896), and one in 

 autumn (killed striking the Eockabill Lighthouse lantern, Co.
