On 31st May 1880, I saw turnstones on the island of 

 Hysgeir off Canna, and on 8th June 1883, while rowing off 

 to our yacht the " Medina," from the same island with Mr 

 Dalgleish, we saw four or five turnstones sitting on a point. 

 I shot one, which proved to be a female not quite in full 

 breeding plumage. 



9. Totanus hypoletccos (Linn.) — Common Sandpiper. — 

 Harvie-Brown mentions having seen two during his visit. 



10. Sterna macrura, Naum. — Arctic Tern. — Colonies bred 

 both on Eilean Eashal and Eilean Craigeach, and Harvie- 

 Brown took eggs from the little island No. 4. 



11. Lams canus, Linn. — Common Gull. — Observed on 

 both visits, being very abundant in most of the islands, but 

 more particularly on Eilean Eashal. At the time of Harvie- 

 Brown's visit the nests had been newly harried by the lobster 

 fishermen, and consequently comparatively few eggs were 

 found. 



12. Larus argentatus, Gmel. — Herring Gull. — Moderately 

 common on all the islands, but chiefly on Eilean Craigeach, 

 from the cliffs on the north-west of which I took some eggs. 



13. Larus fuscus, Linn. — Lesser Black-backed Gull. — 

 Decidedly more common than the last-mentioned species. 

 A colony was breeding on Eilean Craigeach. 



14. Larus marinus, Linn. — Greater Black-backed Gull. — 

 Harvie-Brown saw a few pairs. I saw one near the south 

 end of Eilean Craigeach, but did not get any eggs. 



15. Procellaria^ pelagica, Linn. — Storm Petrel. — I only 

 found this species breeding on Eilean Craigeach, but I did 

 not visit the islands to the south. I do not think it is likely 

 to be found on any of the islands except Eilean Craigeach, 

 as this is the nearest one to the open sea that has any 

 elevation worth mentioning. Harvie-Brown visited all the 

 other islands except South Ascrib, but did not find the bird.^ 

 I think it was more by good luck than anything else that I 

 found their breeding place. I should think that about thirty 

 pairs breed on Eilean Craigeach, because when I was there 

 many of the burrows were empty though new, and the four 

 eggs I did get were quite fresh.
