Type, as fixed by Gray, 1855, Trogon collaris Vieillot.) 

 Pothinusb Cabanis and Heine, Mus. Hein., iv, Feb., 1863, 180. (Type, Trogon 



atricollis Vieillot.) 

 Eapalophorus<^ Cabanis and Heine, Mus. Ilein., iv, Feb., 1863, 199. (Type, 



Trogon surucura Vieillot.) 



Rather small and delicately-built Trogons with serrated tomia, 

 relatively small and weak bill, lateral rectrices always broadly tipped 

 (usually also barred) with white, the auricular feathers not elongated, 

 slender, nor filamentous, and the adult female without metallic colors. 



Bill relatively small (not more than half as long as head), the cul- 

 men rather strongly arched, usually distinctly ridged, not depressed 

 basally; tomia distinctly serrate; gonys about half as long as man- 

 dibular rami or a little less, distinctly convex, strongly ascending ter- 

 minally, the tip of mandible forming a distinct ascending point; 

 interramal space about as broad basally as long. Nostril roundish, 

 nonoperculate, mostly hidden by distinct antrorse, decurved bristles; 

 feathers of chin and malar apex also antrorse and bristle-like, the 

 former strongly recurved. Seventh, or seventh and sixth, primaries 



o- Possibly T. melanocephalus illaetabilis Bangs, in which case the name of this bird 

 would be Trogon melanocephalus capistratus (Lesson).
