SAXICOLA. STONECHAT. 



of the Friiticicolae and Phoenicuri, differs but very slightly from 

 that of the Motacillae and Anthi, and is merely narrower 

 than that of the Musicapse. The Saxicolae differ from tjie 

 Fruticicolae in having long straight wings, and rather long tarsi, 

 in place of short curved wings and moderate tarsi, as well as 

 in other respects. The Sialiae or Blue-birds of America have 

 the wings of the Saxicolae, with the bill of Erithacus, and very 

 short tarsi, like those of Flycatchers, but stouter. 



Only one species of Saxicola occurs in Britain, and is migra- 

 tory, arriving about the middle of spring, and departing about 

 the beginning of October.
