The wings of the males measure : 100, 09, 98 ; the tall 01 — 03 mm. 



The specimens are in freshly moulted plumage, with broad pale brown edge to 

 the feathers ; the bill in the dried skins appears pale horn-colour, the lower 

 mandible being almost brownish white. Natterer considered a bird with a brown 

 bill and of rather large size, which he had obtained at Santarem, to represent the 

 true L. militaris, and separated specifically those with black bills and of rather 

 smaller dimensions, collected on the Rio Madeira and near Para, as L. erythrothorax. 

 This distinction, however, cannot be upheld, for both snjrposed forms are to be found 

 together in Surinam, on the Orinoco, in Bogota collections and elsewhere. The pale 

 bill seems to indicate immaturity.

It agrees with several topotypical specimens from Nauta. The feathers of 

 the forehead and vertex are slate-grey, with small dusky spots and narrow white 

 lateral edges. A series of true T, m. maculatum from Snrinam and British Gniana 

 has the front and anterior portion of the crown distinctly black, with the white 

 edges more pronounced. Specimens from Para belong also to the typical form.

 Not yet recorded from the Lower Amazons, but known to occnr in Venezuela 

 and ou the island of Trinidad.

No. 543. ? ad., Urucuritnba, Santarem, 7. ii. 00. " Iris brown, feet and 

 bill black." Wing 52 ; tail 59 (in moult) ; bill 10 mm. 



This specimen agrees with those collected by Natterer on the upper Rio 

 Madeira, the markings ou the wiugs and tail being yellowish white. In the type 

 from Eastern Bolivia they are pure white, but this is not likely to be a constant 

 character. 



The locality Santarem extends the range of the species far to the north, it 

 having previously been only known from the headquarters of the southern tributaries 

 of the Amazons (Ucayali, Rio Madeira, etc.). Like Serpophaga caudata, it appears 

 to be an inhabitant of the banks of great streams.

No. 585. ? ad., Urncurituba, Santarem, 20. ii. 00. " Iris brown." 

 Not different from Bahia skins, perhaps the belly a little paler yellow.
