 Ivegiilus satrapa, var. olivascens, Baird, Rev. Am. B. p. 65 (1864). 



This species, although verj- similar to it. ignkapillus in general 

 colour and appearance, can always be distinguished by the following 

 differences : — 1. The old male of 11. sutraj^a has the hind neck and 

 the sides of the neck grey, with only a very slight olive hue, whilst 

 in R. icinicajiillus these parts are of the same intense olive-green 

 colour as the mantle, gradually passing into olive-yellow on the sides 

 of the neck ; 2. The foi-ehead is white instead of buff or cream- 

 colour ; 3. The centre of the crest is no doubt brighter- coloured. 

 The females of both species are alike in colour ; and the young birds 

 are without the coloured crown. Length of wing 2-1-2-25 inches, 

 tail 1-75, tarsus 0'65. 



Hah. The American Fire-crested Wren is found throughout 

 North America, extending thence into Mexico. 



Ohs. Professor Baird remarks that " the western specimens are 

 much brighter and more olivaceous above, especially on rump and 

 tail, than the eastern, and may possibly constitute a different race, 

 or variety olivaceits." The British Museum has no specimens of 

 Ii. satrcqja from Eastern North America.
