On the other hand, skins from Minas, Rio, S. Taulo and Paraguay are decidedly 

 larger, the wing measuring from 68 to 71, the tail from 40 to 48 mm. The throat 

 patch is deep black, as in the northern birds. This southern form is apparently 

 entitled to the name />. cayana cyanater Less.* 



3. Tachyphonus cristatus cristatus ((tin.) 

 Tauagra cristate (Jmelin, Sijxt. Xat. 1. ii. p. X98 (1788— ex Brissou et Buffon : Cayenne). 



Nos. 584, ii 14. 3<$ ad. 7. Hi., 10. iv. 06. " Iris brown, bill and feet black." 

 The differences between T. c. cristata, of Cayenne, and T. c. cristatellus, of 

 Bogota, etc., as pointed out by me in Nov. Zool. xii. p. 275, are apparently not 

 constant. We have lately received an adult $ (and I have seen others) from Eastern 

 Ecuador with the crest of the same reddish orange tinge as our Cayenne specimen, 

 while the two Obidos skins, which ought to belong to the Cayenne race, agree in the 

 bright orange-red colour of the crown with the series from Bogota, etc. They are, 

 however, quite different from T. c. brunneus {brasiliensis Scl.), the crest being much 

 shorter, lighter, and bordered in front and laterally by a very distinct fulvous buff 

 line, which is but slightly indicated in the East Brazilian form. 



T. e. cristatus is new to the Lower Amazonian fauna, though it was collected 

 near Borba, Rio Madeira, by J. Natterer.

The crowu and sides of the head are even brighter orange than in specimens 

 from Trinidad and Cnmana. 



In my revision of the genus Pipra (I.e.) I mentioned Para and Rio Capim 

 among the localities of P. erythrocephala, but Miss Snethlage (in lift.) has since 

 informed me that this species does not incur in the Para district, and that the 

 i 'iipiin examples, collected by Dr. Goeldi, belong to /'. rubrocapilla. Layard's 

 specimen was lost, and there is only one Wallaciau skin in the British Museum,
