Tiiil of Sa.ricola cananth/ 



The genus Sa.ricola contains thirty or more species of birds, none 

 of them much larger or smaller than a Robin. The bill is slender 

 and black, and only moderately furnished with rictal bristles. The 

 legs are also black, and the tarsus unscutellated. In every species 

 the bastard primary is small, and the wings comparatively fiat and 

 pointed. The tail consists of twelve feathers of nearly equal length. 

 The most important character, however, is to be found in the colour 

 of the rump, upper tail-coverts, and the base of the tail, which 

 in typical species is white. One species (S. xanthoprymna) is 

 aberrant in the colour of the rump and upper tail-coverts, but is 

 typical in the colour of the tail, whilst three species {S. moesta, 

 S. cJirysopygia, and S. galtoni) are Ruticilline in the colour of the 

 rump, upper tail-coverts, and tail. These species maj', however, 

 be distinguished from the genus Rutlcilla by the proportion be- 

 tween the culmen and tail. In RuticiJla the tail is more than 

 iowT times the length of the culmen, whilst in Saxicola it is less.
