unique iu the Vieuna Museum. T. lenciira is a near ally of T. (dbitorqucs* witli 

 which it agrees in having the lores beset with black feathers, and the auricular 

 region whitish ; but differs at a glance b}' its pale greyish, at the tip almost white 

 tail, without any trace of black. The bill too is much sniallcr. Although the 

 type is an immature bird, I think there can be no doubt about its being an excellent 

 form. It has the following dimensions : wing 1IC2 ; tail 65 ; bill 16 mm. 



Fartlier south, on the Rio Guapore (Villa Bella dc Mattogrosso, Engenho 

 do Gama), iu Western Mattogrosso (Cliapada, Corumba), and in Eastern Bolivia 

 (Ohiquitos, Santa Uruz-de-la-Sierra), another closely related sjjecies, T. pelzelni 

 Salv. & Godm.,t is met with. This form is nearly allied to T. i. inquisitor, of 

 South-Eastern Brazil, but differs by the greater extent of white at the base 

 of the tail ; besides, the rectrices show distinct white a]ucal margins. From 

 T. alhitorqui's and T. leucura it may at once be distinguished by its black (instead 

 of white) ear-coverts.]

The female of H. minor may easily be distinguished from that of II. rii/ics 

 (citricapiUus) by its blackish (not yellowish white) lower mandible. Besides, the 

 back is dull olive, but slightly mixed with brownish, instead of being, as in 

 H. rufus, bright cinnamon-rnfous like the upper tail-coverts ; the cheeks, auricular 

 region, and under parts are much darker, dee|i ocliraceous, instead of buff, etc., etc. 



//. minor is new to the fauna of the Uio Madeira ; but Natterer got a male 

 on the Rio Guajiore,J and U'Orbiguy obtained specimens in (luarayos and Yuracaros,
