The original specimen of P. conversi described by Bourcier came from Colombia, and 

 was sent thence by M. Convers, who lived for some time at Bogota ^. The presence of 

 the species within our limits was first noticed by M'Leannan, who obtained a single 

 male specimen in the dense forest near the Line of the Panama Eailway, and sent it 

 to Mr. Lawrence ^. It was subsequently found in Costa Eica by Arce, and also at 

 several places within the limits of the State of Panama. Its southern range reaches 

 Ecuador, where specimens have been obtained by several collectors. Stolzmann's 

 examples from that country were described by Von Berlepsch and Taczanowski as 

 Gouldia conversi ceguatorialis, but they hardly differ from the typical Colombian form. 

 The head and throat are perhaps a little brighter, and in this respect the Central- 

 American birds agree with those of Western Ecuador. 



Suborder CYPSELI. 

 Pam. CYPSELID^. 



This suborder is spread over the whole of the temperate and tropical portions of the 

 globe, and comprises about 78 species, the American Continents claiming about one- 

 third of these. 



Kecent authors divide the Cypselidee into two sections, based upon the number of 

 phalanges in the third and fourth digits of the adult bird. The first of these sections 

 forms the subfamily Cypselinae, in which the second, third, and fourth digits have each 

 three phalanges. In the second section the toes are of normal structure, the third toe
