Birds of Paraguay. 619 



(1) D. cay ana ultramarina Lawr., from Eastern Nicaragua to 

 Panama, which is distinguished by its more blue appearance. 

 (2) D. cayana glaucogularis Berlepsch & Stolzmann, from 

 Colombia, Ecuador, Peru, and Bolivia, which differs in 

 having more green on the throat. (3) D. cayana cayana, from 

 Guiana and Trinidad, which is rather smaller in size, with a 

 somewhat larger black patch on the throat. (4) D. cayana 

 paraguay ensis, from Paraguay, Matto Grosso, and S.E. Brazil, 

 distinguished by its larger size and large black throat-patch. 



The specimens from Chiriqui, whence Mr. Bangs described 

 D. cayana callaina, are very similar to D. cayana glauco- 

 yularis and scarcely to be distinguished from that race. 



[Resident and fairly common in the large forests of this 

 district. I have at times met with it on the very edge of 

 the woods. It is very hard to find out anything positive about 

 our Paraguayan wood-birds. The montes are so dense and 

 gloomy that in the first place it is difficult to see them, and 

 then when disturbed a flight of a few yards will take them 

 beyond the vision of the hunter. The woods are so thick 

 and tangled with fallen trees, where the vines bind all to- 

 gether into one almost impassable mass, that it is impossible 

 to follow a bird for any distance, and the mere fact of 

 breaking through the undergrowth would frighten it into 

 silence, while without movement on the part of the birds it 

 is quite hopeless to try and distinguish them in the changing 

 lights and shadows of the forest. The only hope is to 

 remain perfectly motionless, when first one and then another 

 will betray its presence by some movement. — W. F.~\
