CONTOPTJS, 85 



parts during the breeding-season. The line of its southern migration does not appear 

 quite clear. We certainly find it in the North Mexican State of Nuevo Leon and 

 again on the islands of Cozumel and Euatan and on the mainland of Honduras, but 

 we have not met with it again till we come to Santa Marta in Colombia, where 

 Mr. Simons obtained a bird undoubtedly of this species in 1879 ; thence it passes into 

 Ecuador. It will be noticed that we have not included Guatemala or Panama as 

 within the winter range of this bird, though specimens from those countries, which we 

 now believe to belong rather to C. richardsoni, have been assigned by Mr. Sclater to 

 C. virens. We think on the whole they are best placed here. Other Mexican localities 

 are inserted on the authority of Sumichrast's specimens ^ ^ ; and as regards Costa Rica, 

 Hoffmann's example, as determiued by Prof. Cabanis ^, is the only record we have of its 

 occurrence there. 



The habits of Confopus virens are fuUy given by American authors, with whom it is 

 a very familiar bird. Its nest is described as a beautiful saucer-shaped structure, 

 covered exteriorly with green and grey lichens, and usually secured to a thick horizontal 

 branch of a tree. The eggs are pale creamy buff or creamy white, spotted, generally in 

 a ring round the larger end, with rich madder-brown and lilac-grey.
