ochreons or fnlvons colouring; the middle of the abdomen pure white; the axillaris 

 and under wing-coverts much duller, and the inner web of the quills nearly uniform 

 greyish brown.

 This is quite a young bird, agreeing with another specimen from East Ecuador 

 in corresponding plumage.

The adult bird agrees with specimens from North Pern, except in having a 

 slightly longer tail. As regards coloration, examples from North Peru (including 

 the type of S. rufogularis Des Murs, belonging to the Paris Museum), Teffe, and 

 from the valley of the Rio Junta, W. Brazil, are perfectly identical among them- 

 selves. All have the throat, foreneck, front and sides of the head of a deep 

 ferruginous red, and the abdomen decidedly rufescent brown. 



The two typical specimens of T. modulator from Yuracares (Paris Museum) 

 and a ? from Northern Bolivia (in Count Berlepsch 's collection) differ from this 

 series by the much lighter tone of the ferruginous portions of the plumage, and by 

 having the abdomen almost pure olive brown with scarcely any rnfescent tinge. It 

 seems therefore advisable — for the present at least — to keep the two forms separate, 

 though it is not improbable that additional specimens from Bolivia might prove 

 them to be identical. 



A third nearly allied form, L. modulator salvini (Sharpe), occurs in Eastern 

 Ecuador. It differs from the two others chiefly by having the ear-coverts uniform 

 dark sepia brown (instead of rufous). I have examined five specimens, including 

 the types.
