A similar foreign element appears to have intruded 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 these 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 per cent, of the whole, after excluding the species of wide range. As shown by the subjoined table, these Para species are not unfrequently representatives of allied forms in Cayenne, in some cases so closely allied as to be hardly distinguishable (e. g. Urogalba amazonum, Thalurania furcatoides), in others so well marked as to allow no question as to their specific validity, such as Xipholena lamellipennis and Celeus jumana. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12.
