With regard to the S ad. from Sautarem (batterer coll., Vienna Museum) 

 I have made a erroneous statement in The Ibis for 1906, p. 8, repeated in Xo>:. Zool. 

 xiv. 1907. p. 3.J.S, in assorting 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 ^.n^fasciicaiula, hitherto regarded as distinct species, 

 though I had suspected their subspecitic affinities for a long time. While agreeing 

 with average examples of aureola from Surinam, etc., in general coloration, 

 especially in the black sides and nnder 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. 

 Further material is recjuired 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 aad Jasciicauda, which 

 henceforth can be regarded as only subspeciflcally distinct.

For the locality Borba (Natterer) see above, p. 303. 



c? ad. Agrees with P. a. aureola in having the sides, under tail-coverts, and 

 the rectrices lilack ; 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 37—30 mm.

Hab. Eastern Bolivia, headwaters of the Rio Mamor6 : Yuracares, Guarayos, 

 Santa Cruz de la Sierra (D'Orbigny), San Mateo (G. Garlepp in Bins. H. v. 

 Berlepsch). Central and Western Brazil from the Paranil, Parauapauema, and 

 Paranahyba Rivers (Araguary) in the south, northward to Goyaz (Natterer, Baer) 

 and Mattogrosso (('hapada; Villa Maria on the Rio Paraguay; Villa Bella de 

 Mattogrosso and Engenho do Gama, on the banks of the Rio Guapore). Also 

 obtained by Mr. W. Hoffmanns near Maruins, above the waterfalls of the Rio 

 Machados, right-hand tributary of the Rio Madeira, and at Itaituba, left bank of 

 the Rio Ta)iaj('iz. (Cf also Mop. Zool. xv, 1908. p. .")4.) 



S 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 andj/avicollis, but nearer the latter. Throat
