This series fully corroborates what I said in Xor. Zoo/, xiv. I'JOT, p. 40. The 

 upper parts are always lighter or darker " luummy-brown " (Ridgw. t. iii. fig. 10) ; 

 foreneck, breast, and sides " wood-brown " (Ridgw. t. iii. fig. 19) or earthy brown 

 with a slight rufescent tinge ; the middle of the abdomen is largely white, the under 

 tail-coverts white with dark brown bases. The axillaries and under wing-coverts 

 are ochraceous buff, or wood-brown washed with pale ochraceous at the tips. 

 Sometimes there is a narrow, ill-defined, bnft' edge along the inner web of the 

 remiges, but in most specimens the latter is iinite or nearly uniform greyish. 



The young bird (No. -107), when compared with 7'. fiimujatus in corresponding 

 age, shows the distinctive characters even more strongly emphasized than the 

 adults. In Nos. 708 and 82 some hairlike filaments are to be seen among the 

 normal feathers of the nape. This particularity has also been noticed by 

 Lichtenstein in the allied 7\ fumigatiis* 



The female of T. leiicops Tacz. bears a striking likeness to T. hauxivelli, but, 

 on closer examination, may easily be distinguished by the deep orange under wing- 

 coverts, more regular and darker, blackish brown stripes of the throat, and 

 especially by the different wing-formula, the third, fourth, and fifth primaries 

 being longest, and the second ei|nal to the sixth. In T. liaiixiceUi, on the other 

 hand, the fourth and fifth form the tip, the sixth is but from 2 to 3 mm. shorter, 

 while the second falls between the seventh and eighth primaries. 



It is a curious fact that Mr. Hoffmanns should have met with T. hauxwelli 

 in the Rio Madeira district, while Natterer, eighty years ago, obtained its ally, 

 T. fumif/atus, at nearly the same places {vide infra). 



T. ltau.vwelU has evidently a wide range in Amazonia. Unlike so many other 

 Upper Amazonian types, it inhabits the left (Ilumaytha) as well as the right bank 

 (S. Isabel, Calama) of the Rio Madeira. Farther to the west it was obtained by 

 Garbe on the Rio .Turua, and by the expeditions of the Goeldi Musenm on the 

 Upper Purus. Hofl'manns sent a specimen from TefFe, Rio Solimoens. In Peru 

 several naturalists — E. Bartlett, Castelnau k Deville, Hauxwell, and Whitely — 

 secured specimens on the bauks of the Maranon, at Ii|uitos, Pebas, Nanta, Samiria, 

 etc. The first-named of these travellers also took an example near Santa Cruz, 

 on the Ucayali, and Dr. Allen records two specimens from Reyes, on the liio Beni, 

 Northern Bolivia.
