EEGULUS. 49 



perhaps, Guatemala during the winter months are probably immigrants from the 

 north ; but on this point our evidence is scanty. 



In Mexico it has only been noticed in the neighbourhood of Orizaba ^ and in the 

 highlands near the city of Mexico. Its presence in Guatemala must be considered 

 doubtful, as the only evidence of its being found there rests upon the fact of Salvin 

 having recognized a bird that flew across the road a few yards from him when riding 

 from Totonicapam to Los Encuentros in February 1874. 



The habits of this species are fully described in the works on North-American birds 

 we have quoted above. Concerning its song some difierence of opinion prevails, 

 Dr. Brewer speaking in high praise of it, whilst Dr. Coues has little to say in its 

 favour. If it at all resembles that of Begulus cristatus, we should certainly pronounce 

 it a very poor performance.

This well-known North-American Begulus has a wide range over that continent, 

 being found from the shores of the Arctic Sea to the Gulf of 'Mexico, and from the 

 Atlantic to the Pacific, and has even been known to stray to Greenland. It is a 

 migratory species; but the majority of the birds do not pass beyond the Southern 

 States in winter, being found in some abundance in that season in Texas ^^. In Mexico 

 it is probably only a winter visitant ; and it would seem to be not common there, 

 as several of the most assiduous collectors in that country have failed to meet with it. 

 In Guatemala its presence is assured from specimens having been sent from there by 

 Mr. Skinner ^ (one of which, doubtless from this source, is in the Smithsonian Insti- 

 tution ^) ; and this is all that can be said concerning it in that country. We have never 

 ourselves met with a single specimen in the large Guatemalan collections of bird-skins 

 we have examined. When crossing the ridge of mountains between Quiche and 

 Totonicapam, Salvin thought he recognized this species in a bird that flew across his
