ON A COLLECTION OF BIRDS FROM TEFFE, RIO 

 SOLIMOES, BRAZIL. 



By C. E. IIELLMAYR. 



AFTER leaving Obidos, Mr. W. Hoffmanns went to Telle (Ega), on the south 

 bank of the Bio Solimoes, where be was at work from the last week of 

 May to the end of Jnne. Although the collection is not a large one, it proves 

 to be of considerable interest, showing once more how much remains to be done in the 

 ornithology of the Amazon valley. The Rio Solimoes is even less known than 

 the Lower Amazons, though visited by several naturalists. The Bavarian expedition 

 ninler Spix and Martins obtained a few specimens at S. Paulo d'Olivenea and near 

 Tabatinga. Count t'asteluau transmitted a good many birds from Fonteboa and 

 Ega to the Paris Museum, but only a few species were mentioned in the ornitho- 

 logical portion of the Expedition dans les parti?* centrales de FAnbriqiie du Slid, 

 while the greater part remained uuworked in the French national collection. 

 Mr. II. W. Rates spent more than four years in Ega and its neighbourhood, 

 and thongh chiefly interested in entomology, managed to bring together a fair 

 number of ornithological specimens, which, however, were never reported upon. 

 The only paper that seems to have been published on his material appeared in 

 the Proceedings of the Zoological Society for 1857, pp. 267-68, wherein Mr. Sclater 

 records twenty-three species of birds as having been collected near Ega. Natterer 

 obtained some birds on the "lake" Manaqneri, which were duly enumerated by 

 von Pelzeln in his well-known work " Zur Ornitholoyie. Brasiliens." Lastly, Mr. G. 

 Garlepp, on his way to Pern, made a short stay at Fonteboa and Tonantius, where he 

 procured specimens of twenty-six species, an account of which was published 

 by Count Berlepsch in the Journal fur Ornithologie, 1889, pp. 97-101. 



The avifauna of Teffe differs essentially from that of the Lower Amazons, 

 agreeing more closely with that met with on the banks of the Rio Marauon, in 

 Northern Pern. Other remarks on the zoogeography of the Amazon valley I defer 

 to a later occasion. 



In the preparation of this paper I have been greatly assisted by Count von 

 Berlepsch and Dr. Lorenz von Libnrnan, who most kindly lent me many specimens 

 for comparison.

Turdut hauxwelli Lawrence. Aim. Lye. Nan York, ix. p. 2G5 (18G9 — Pebas, X.E. Peru). 



No. 727. <? ad., 31. v. 0G. " Iris light brown, bill greyish green." — Wing 113 ; 

 tail 96 ; bill 20 mm. 



This bird agrees well with topotypical examples from Pebas. T. hauxwelli is 

 an excellent form, not to be confounded with T. fumigatus Lcht., from which it 

 differs in many important points. The upper parts are much duller and darker, 

 about " mummy-brown" (Ridgw. iii., fig. 10), without any ochreons hue ; foreneck, 

 breast, and sides, instead of beiug bright ochraceons brown, are "wood-brown," a 

 little more rnfesceut than Ridgway's pi. iii. fig. 19 ; the under tail-coverts dark 

 brown on the basal and pure white on the apical portion, without any trace ot
