 colour, but each feather is marked down the middle with pale reddish casta-

Habitat, Galapagos Archipelago. (September). 



This bird is not uncommon on these islands. It has the habits of our Sylvia?. 

 It frequents the thickets in the lower, dry and rocky parts of the island, and 

 especially a peculiar bush, with thick foliage, which grows only near the sea- 

 coast. 



Cvanotis omnicolor. Swains. 



Eegulus omnicolor, Vieill. Gal. pi. 166. 

 Sylvia rubrigastra, Vieill. 



Regulus Byronensis, Gray, Griff. An. King. pi. 

 Tachuris omnicolor, D'Orb. fy Lafr. 

 Tachuris roi, Azara, No. 161. 



My specimens were obtained at Maldonado in June, and therefore probably 

 it is not a bird of passage. It frequented reeds on the borders of a lake, but 

 was exceedingly rare. I likewise saw one in Northern Patagonia, and in a 

 collection of birds at Santiago, in Chile, made there by an inhabitant of the 

 place. The soles of the feet of this exquisitely beautiful little bird are bright 

 orange.
