about iuterestiiig results. Indeed, a return I have received from 
Cape ^\ratb Liglitliouse I think, shows this, as also others from 
Stoii-Head Lighthouse, and other stations. I watched with my 
glasses for some time the face of the low mural precipices of Eilean- 
Mhuire, and I could distinctly watch the approaching birds before 
they crossed the isthmus. Thus, I was able with certainty to fix 
their j3oint of departure. Their great feeding grounds I believe to 
be the narrower waters of the Minch and opposite the entrance of 
the Sound of Harris, 
10. I>LACK Guillemot. Una gnjlle (L.). I only saw two 
and received an egg ; but I understand they breed principally on 
the Galta Eock, and a few on Eilean-Mliuirc, which as before 
stated, we were unable to visit. Hone however were seen passing 
over the isthmus. 
11. Lesser Black-backed Gull. Larus fusciis (L.). Common, 
breeding on the more level parts of the summits of the islands, 
especially ujion Garbh-eilean and its Siamese twin Eilean-a-chille. 
12. Herring Gull. Larus argent at us (Gm.). About equally 
common with the last, and breeding in similar positions. 
13. Kittiwake. liissa tridactijla (L.). Abundant on certain 
portions of the cliffs, especially at the west end of the columnar 
cliffs of Garbh-eilean, and on Eilean-Mhuire and the south-east 
side of Eilean-a-chille. 
14. Shag. Phatucrocorax cristatus (Faber). A very few 
observed. The shepherd’s family gave me one egg. 
^ Lord Teignmouth speaks of the sea-fowl of the larger 
kind: “Solan Geese and Cormorants swarm in prodigious numbers.” 
Solan Geese, however, do not breed on the Shiants, nor are 
Cormorants (or Shags either) to be found in largo numbers. 
Possibly Lord Teignmouth, however, may during his visit, have 
witnessed the annual migration westward of the Solan Geese past 
the Shiants. Elsewhere I have occasion to speak of the annual 
inigiation of liock Birds past the lighthouse stations of our north 
and west coasts {v. ‘Zoologist’ for May, 1880).
