462 MOMOTID^. 



With this bird we place Urospatha martii, as has been already done by Count Berlepsch. 

 Urospatha, so far as we can see, differs only in having spatules to the ends of the central 

 rectrices, an ornament produced by the bird itself, and, as our specimens show, often 

 absent. 



The number of rectrices is ten, the bill stout and compressed, and the serrations to 

 both the maxilla and mandible very large, even coarser than in Momotus. The 

 antrorse loral feathers are long, the radii being distinct ; these feathers reach beyond 

 the nostril when stretched forwards, lying below and not covering the opening. The 

 nostrils themselves are at the extremity of the nasal fossa, are slightly oval, and 

 bordered behind by membrane. The tarsi are rather strong and have about the same 

 relative proportion to the wing as is found in Eumomota, and are thus comparatively 

 shorter than in Momotus, but the difference is small. 



Of the two species of Baryphthengus, B. martii occurs in the whole of the Upper 

 Amazonian region, in Colombia, and in Central America as far north as Nicaragua, 

 while B. ruficapillus is found in Eastern and South-eastern Brazil and Paraguay.

 after his companion and coadjutor in their great work on the fauna and flora of that
