and greater ripper tail-coverts uniform black, while they are marked with large white 

 apical spots in the Hnmaytha bird. '/'. punctuliger Pelz., from Borba, agrees 

 in this respect, but has a distinct coucealed white interscapular spot, of which 

 there is no trace in T. polionotus, from Hnmaytha, Bio Negro, ('aura, etc.

Perfectly identical with specimens from Para. The Tring Museum possesses 

 also an adult male found in Bogota collections, which is not different either.

 bill blackish grey." 



The adult male differs from our Teffe specimen by having the forehead more 

 densely striped with white, and particularly by the crest-feathers being distinctly 

 white at their base, though to a less extent than in T. d. doliatus (Linn.). 



T. nigricristatus Lawr., T. subradiatus and allies are evidently all geographical 

 representatives of T. doliatus, and, therefore, more properly designated by 

 trinomials.

Agreeing with specimens from Para, Teffe, and Venezuela. The young has 

 a much smaller, entirely black bill, while in the adults the lower mandible is 

 always pale greyish horn-colonr.
