382 THE ZOOLOGIST. 
North Rona or Ronay is confused (by strangers to the isles) with 
three other islands of the same name, Rona or Ronay. There 
are in all four isles, or groups of islets, which bear the names of 
Rona, e.g. North Ronay, situate north-east of the Butt of Lewis, 
and north-west of Cape Wrath, and forming the apex or north 
point of an equilateral triangle, having for its base a line drawn 
between the Butt of Lewis and Cape Wrath. Closely associated 
with it is North Barray or Sulisgeir (i.e. if sixteen miles by sea 
be considered association, and of which we have more to say in 
the later part of this paper). Then we have South Ronay, 
which is synonymous with Ronin, or the Island of Rum, and 
Kast Ronay, which lies close to and immediately to the north of 
the Island of Raasay (sic), between Skye and the Mainland. And, 
lastly—so far as we are here concerned—we have West Ronay, 
an island lying close to and at the south-east extremity of the 
Island of North Uist. 
The error which originally appeared, however, whilst affect- 
ing these positions in an indirect sense, or complicating the 
issues, really was more clearly caused by a confusion of the 
positions of several islands and islets of the name of Barra, 
Bara, or Barray. Shortly stated, these are North Barray (or 
Sulisgeir), already mentioned, and ‘‘ the South Isles of Barra,” 
at the southern extremity of the Outer Isles, and which include 
Barray, Mingulay (sic), Muldonich, Vatersay, Pabbay, Barra 
Head or Berneray, and other smaller rocks, islets, stacks, and 
skerries. North Barray and the Isles of South Barra are some 
one hundred and sixty-five miles apart. 
Atkinson appears to have been the first person to have 
stated that Fulmars nested not only on St. Kilda, but also “‘on 
the Isles of South Barra.” * 
This, in part at least, but somewhat indefinitely, was quoted by 
John Wolley. He evidently intended to correct Atkinson’s state- 
ment, and says: ‘‘ It is, however, said to breed in the Island of 
Barra—perhaps not South Barra—and on Rona”’ (the italics are 
those of the present writer). But Wolley, in his statement expla- 
natory, introduces a further trouble by speaking of Rona and 
‘‘ Sulisgeir ”’ (or North Barra) as two rocks lying “‘ far to the north
