MUSCICAPIN^. 



Genus Chelidorynx, mihi. 



General structure of Rhipidura, but the bill very short and Crypto- 

 lopho-hirundine, being as broad as long from the forehead and 

 very slightly armed at the tip ; rictal bristles long, as in Rhipidura ; 

 nares advanced, lateral, elliptic, and shaded above by a membrane ; 

 tail rigid, with -vvedged tips to the plumes, smaller and less rounded 

 than in Rhipidura. 



Type, Ch. chrysoschistos, mihi. — Above slaty, with a greenish 

 smear ; below bright yellow ; wings and tail dusky ; shafts of the 

 caudals -vvhitened ; ears, lores and orbits black. Length, 4| inches ; 

 bill to gape, f ; tail, 2^ ; wing less 2į ; tarse, ^ ; centrai toe and 

 nail, -^ ; hind, -^. Weight į oz. Inhabits the centrai hilly region 

 and great valley, on skirts of \voods, among shrubs and low trees ; 

 very lively and shows itself much ; solitary or in pairs. Stomach 

 distinctly muscular ; diet small insects. 



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

 lopha, to which lašt it is allied by the bUl, vvhich however is shorter 

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

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

 from the Flycatchers to the Swallows.

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

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

 Types, H.fuUginosa and f erruginea.

 nally blackish, and more or less so apertly ; bill dusky cameous ;
