The lluticillce or Hed-tails^ have long slender legs, 
tolerably long wings, and somewhat rounded tails, which 
are rusty or fox red, except the two middle ones. The 
males, and females, and young differ in plumage.

Syloia erijthrogastra is an inhabitant of the Caucasus 
during the summer, migrating about the end of October 
to a warmer climate. It was first described by Glil- 
denstiidt in 1775, and was subsequently confounded with 
the Motacilla aurorea of Pallas, which is not, however, 
a European species, and is distinguished from it by 
the following characters, as given by Schlegel: — First, 
the two middle feathers in the tail of aurorea are 
black and not brown red. Second, the white mirror 
.of the wings occupies the secondary quills to the 
eighteenth. Third, aurorea is altogether smaller, the 
total length being six inches ; the wings three inches 
one line; tail two inches eight lines; tarsi eleveii lines; 
middle toe six lines; and the hinder toe three lines. 
According to Glildenstadt the manners and habits of 
this 'Warbler are similar to the rest of the family, ap- 
proaching nearest to those of the Common Bedstart. 
It lives on the shores of rivers, and is not a shy bird. 
It feeds on insects, and berries of the Ilippophoe 
rhamnoides, in which also it builds its nest with grass. 
Nothing seems to be known about its eggs. 
The figure which we have given of this bird is from 
Count M aide’s monograph, and is a copy of the speci-
