This type seems to require a place between Rhipidura and Crypto- 

 lopha, to which last it is allied by the bill, which however is shorter 

 and broader, leading to the next singular form, which is a flycatcher 

 in the guise of a swallow, and forms with this one a perfect passage 

 from the Flycatchers to the Swallows. 



Genus Hemichelidon, mihi. 



General structure of a swallow, with only something Muscicapan 

 in wings and rictus ; bill as in Hirundo exactly, but the gape hardly 

 so wide and slightly bristled ; nares round and vertical, as in Hirundo ; 

 wings long and pointed ; 1st quill spurious, 2nd long, 3rd longest ; 

 tail moderate and subfurcate ; legs and feet small and slender. 

 Types, H.fuliginosa emdferruginea.

 and tail, and shaded with white on the belly, vent, and under tail- 

 coverts ; the body below paler than above. Length, A\ inches; 

 bill, I ; tail, 2 ; tarse, -^ ; central toe and nail, less -^-^ ; hind, -^ ;

Found only in the hills, and chiefly the central region ; dwell in 

 woods and have the general manners of the Flycatchers, but with a 

 bolder and more continuous flight.

 very small ; bill more or less elongated and cylindric ; rictal bristles 

 moderate, that is, shorter than in Rhipidura ; tail gradated and

Bill to gape equal to the head, to brow much less than the head ; 

 Anthine in the general character, but stronger, with the culmen, 

 commissure and gonys more or less curved ; base of the upper man-
