in Great Britain during the Nesting-season. 47 
sight of the living bird ought to more than compensate them for 
the loss of the best of flies. 
Hrrunpo rustica (Linn.). Chimney-Swallow. 
Provinces I.—X VIII. 
Subprovinces 1-35, 36, 37, 38. 
Lat. 50°-60° or 61°. “ British ” type, or general. 
Throughout Great Britain, and also reaches the Scottish isles. 
Mr. John Macgillivray describes H. rustica as the only Swal- 
low found by him in the Outer Hebrides, where it did not arrive 
till the end of June. Messrs. Baikie and Heddle say that a few 
pairs build annually near Kirkwall ; and Dr. Saxby tells me that 
a nest was once taken in Lerwick. 
CuELipon ursBica (Bote). House-Martin. 
Provinces I.—X VIII. 
Subprovinces 1-382, 34, 35, 37, 38. 
Lat. 50°-60° or 61°. “ British” type, or general. 
Builds regularly as far north as Sutherland and Caithness ; 
but does not appear to reach the Outer Hebrides, nor has 
Mr. Graham found its nest in the islands of Argyleshire. 
In Orkney, the House-Martin builds at Kirkwall and about 
the Cathedral of St. Magnus (Messrs. Batkie and Heddle). 
CoryLE RIPARIA (Bote). Sand-Martin. 
Provinces I.—X VIII. 
Subprovinces 1-32, 34, 35, 37, 38 ? 
Lat. 50°-60°. “ British” type, or general. 
Ranges to the extreme north of the mainland; but, like the 
former species, the Sand-Martin has not been found breeding in 
the isles of Argyleshire. 
W. Macgillivray has noticed that Sand-Martins frequent the 
sand-banks on the shores of the northernmost Hebrides. They 
build in Orkney, and perhaps occasionally in Shetland.
