As the present article on JEgiothus is going to press, we have received, 

 through the kindness ol' Dr. Brewer, a specimen of what appears to be a 

 third species of yEr/iotJnis, allied to the ^''. fiavirostris of Europe, obtained 

 in Walthani, Mass., by Mr. William Brewster, of Cambridge. This bird 

 was killed in a flock of ^. Unarms, of which five were also shot at the 

 same discharge. None of the others, nor indeed of any of ninety specimens 

 prepared by Mr. Brewster during the winter, were at all like the present one, 

 whicli is entirely diflerent from anything we have ever seen from North 

 America. 



The relationship of tliis bird a]ipears to be nearest to the ^. Jlavirostris of 

 Europe, with the 9 of wliicli it agrees in many respects, as distinguished 

 from liiiarius and cancsccns. The European bird, however, lacks the sul- 

 phur-yellow tinge (which gives it somewhat tlie appearance of Chri/somifris 

 pinus), has the throat and jugiilitm strongly reddish-bulf, instead of dingy 

 yellowish-white, and is nuich browner above ; besides which the tail is longer 

 and less deeply forked, with narrower feathers. 



Habits. Nothing distinctive was observed by Mr. Brewster in regard to 

 the habits of the specimen killed by him.
