( 305 ) 
little yellow on forehead and throat, but they are very nearly matched by several 
examples from Surinam, etc. 
With regard to the d ad. from Santarem (Natterer coll., Vienna Museum) 
I have made a erroneous statement in The Ibis for 1906, p. 8, repeated in Nov. Zool. 
xiv. 1907. p. 358, in asserting that it was in every respect typical of P. aureola. 
On the contrary, a renewed examination of the specimen proved it to be somewhat 
intermediate between aureola and fasciicauda, hitherto regarded as distinct species, 
though I had suspected their subspecific affinities for a long time. While agreeing 
with average examples of aureola from’ Surinam, ete., in general coloration, 
especially in the black sides and under tail-coverts, it resembles Peruvian specimens 
of P. a. purusiana in the markings of the tail, viz. outermost rectrix with a white 
band across both webs, the two next ones with a white patch at the base of the 
inner web, though the latter is not quite so much extended as in the western bird. 
Farther material is required to show whether the presence of white on the outer 
rectrices is a constant feature in birds from Santarem, and it would be unwise to 
base a new form upon a single skin. At all events, Natterer’s example is of great 
interest, proving as it does the near relationship of aureola and fasciicauda, which 
henceforth can be regarded as only subspecifically distinct. 
(6) Pipra aureola flavicollis Scl. 
Hab. Left bank of the Rio Madeira, Brazil: Humaytha, Marmellos 
(Hoffmanns). 
For the: locality Borba (Natterer) see above, p. 303. 
3 ad. Agrees with P. a. aureola in having the sides, under tail-coverts, and 
the rectrices black ; but the red area in the middle of the abdomen is rather more 
extended, as well as more decidedly flammulated with whitish or yellowish; the 
front and sides of the head and the throat are clear yellow, with but a little red 
near the upper and posterior edge of the ear-coverts. (Cf. Nov. Zool. xiv. 1907. 
p. 358.) Wing of nine males 62—64} ; tail 27—30 mm. 
Examined: 1 3 ad., ‘‘ Barra” (type of subspecies); 2 dd ad., “ Borba” 
(Natterer) ; 4 dd ad.,1 ¢ vix ad., Humaytha, 1 ¢ ad., Marmellos (Hoffmanns). 
(ec) Pipra aureola fasciicauda Hellm. 
Hab. Eastern Bolivia, headwaters of the Rio Mamoré: Yuracarés, Guarayos, 
Santa Cruz de la Sierra (D’Orbigny), San Mateo (G. Garlepp in Mus. H. vy. 
Berlepsch). Central and Western Brazil from the Parandé, Paranapanema, and 
Paranahyba Rivers (Araguary) in the south, northward to Goyaz (Natterer, Baer) 
and Mattogrosso (Chapada; Villa Maria on the Rio Paraguay; Villa Bella de 
Mattogrosso and Engenho do Gama, on the banks of the Rio Guaporé). Also 
obtained by Mr. W. Hoffimanns near Maruins, above the waterfalls of the Rio 
Machados, right-hand tributary of the Rio Madeira, and at Itaitiba, left bank of 
the Rio Tapajéz. (Cf. also Nov. Zool. xv. 1908. p. 54.) 
3 ad. Differs from the two preceding races by having no black whatever on 
the belly, the whole abdomen below the crimson breast being clear yellow, and the 
under tail-coverts yellow with narrow, dull black tips or edges. Moreover, the 
rectrices are crossed by a broad, uninterrupted band of white or pale yellowish, 
reaching over both webs. In the coloration of the throat and sides of the head, this 
form is intermediate between aureola and lavicollis, but nearer the latter. Throat
