THE BIKDS OF THE LOWER AiMAZONS. 



595 



The i»urely Brazilian forms which occur in the Para (hstrict and 

 are not known in Guiana are only 15 in number, or less than iU per 

 cent, of the whole. x\ similar foreign element apjiears to have in- 

 truded itself from the Upper Amazons, 18 or about 12 per cent, of 

 species hitherto only known as inhabitants of the Upper Amazonian 

 district occurring near Para. It is worth noticing, however, that 

 about half the^e were procured on the Capim River or Tocantins, 

 where the Peruvian element would appear to be stronger than in the 

 vicinity of Para*. 



There remain only to be considered the species peculiar to the 

 Para district as far as hitherto known, which amount to about 23, 

 or 17 percent, of the whole, after excluding the species of wide 

 range. As shown by the subjoined table, these Para species are not 

 untrequently representatives of allied forms in Cayenne, in some 

 cases so closely allied as to be hardly distinguishable (e. g. Uroyulbu 

 amazoiann, Thalurania furcatdides), in others so well marked as to 

 allow no question as to their specific validity, such as Xipholena 

 lamellijjennis and Celeus jumuna.
