«One specimen, from Puente de Ixtla, Morelos, June 7, 1903 (no. 185750, coll. U. S. 

 Nat. Mus., Biological Survey Coll.; Nelson and Goldman). 



I am not sure that this specimen represents the true T. nisorius, but it evidently 

 comes very near that bird, if not actually the same. Judging from the description 

 and colored plate given in the Proceedings of the Zoological Society for 1869 (p. 541, 

 pi. 45), the type of T. nisorius differs from the specimen described above only in 

 having the imder parts more regularly banded. 



il have not been able to find Real Arriba on any map of Mexico that I have had 

 the opportunity of consulting. Mr. Nelson thinks it is probably in Puebla. 



Three specimens, from Nicaragua.
