BIRDS. 
302. Tringa subarquata {Giild.). Curlew Sandpiper. 
[In Dr. Sinclair's collection, and in the reproduced List of 
Mr. E. I. Shearer.] 
303. Tringa striata, L. Purple Sandpiper. 
Winter visitant ; abundant along the coast wherever there are 
rocks and stones suitable for it ; rarer on the sandy shores. 
We have noted this species as late as the 26th May 1868 
on the Badcall Islands, and it is frequently seen late in 
spring and beginning of summer on the shores and islands 
of the west coast. 
A common winter visitant to the shores of Caithness, which, 
being so rocky, are very suitable to its habits. It usually 
arrives about the 1st of October, and departs the end of 
March or beginning of April, though in backward seasons 
it remains as late as May Day, Mr. Osborne having observed 
about a dozen in Wick Bay on that date in 1861 (0. MSS., 
1868). There are several specimens in the Welbeck Abbey 
collection. 
304. Tringa canutus, L. Knot. 
Mr. Mackenzie reports this bird as common at the Dornoch 
Firth ; we ourselves once saw a large flock of waders at the 
Little Ferry, which we thought referable to this species ; 
none, however, were procured. 
Mr. Osborne records this species as a very rare visitant to 
Caithness (0. MSS.). 
Eecorded as seen by Mr. Eeid ; and Mr. Gray, in his 
Birds of the West of Scotland, says : " On the east coast the 
knot is usually found in small flocks on all the shores 
extending from Berwickshire to Caithness."
