ySo PATAGONIAN EXPEDITIONS: ZOOLOGY. 



Genus ANUMBIUS d'Orbigny & Lafresnaye. 



Type. 



Anumbius, d'Orb. et Lafr. Syn. Av. ii. p. 17 (1838) . A. actiticaudatus. 

 Geographical Range. — Uruguay, Paraguay, Argentina and Patagonia. 



Anumbius anumbi (Vieillot). 



Fiirnarius anumbi Vieillot, N. Diet. d'Hist. Nat. xii. p. 117 (181 7), 

 based on Azara's "Anumbi" (Paraguay). 



Description. — Above pale grayish brown, becoming chestnut on the 

 forehead, crown and back streaked with black ; wings like the back, 

 secondaries vinaceous on the edges, pale tawny on the inner web, ter- 

 tials dark brown, middle tail feathers grayish brown, others blackish with 

 white spots at the tips ; under surface paler than above, buffy on the ab- 

 domen, a little darker on the breast with pale shaft streaks, and white on 

 the throat, separated from the breast and auriculars by a band of small 

 black spots. 



Geographical Range. — Southern Brazil and Paraguay to Argentina 

 and northern Patagonia (Rio Negro and San Bias). 



E. W. White writes of this species: "In Salto (B. Aires), it is very nu- 

 merous about the plantations on the Estancias, where it builds in the 

 forks of high trees, usually the eucalyptus. The nest is constructed of 

 large twigs, and is a fine structure for the size of the bird, 21 inches in 

 height and 48 in circumference, in fact twice as great as that of Mihago 

 chimango. The entrance to the nest, which is near the top, but is not 

 right on it, and is about four or five inches in diameter and neatly 

 rounded, leads downwards by a steeply inclined spiral passage to the 

 bottom. The whole is thickly lined inside with hair, feathers, and wool, 

 making a very soft, downy, and pretty nest, and one that is very difficult 

 to pull to pieces, as the twigs are mostly thorny and strongly interlaced. 



"There were five eggs in the one I took: their shape is elongated, 

 considerably pointed at one end, and pure white, without spots : the only 

 one to which it can be compared is that of Columbula picui ; but it is 

 more acutely pointed." (P. Z. S. 1882, p. 612.)

 Psendoseisura 'R.txokitr^. op. cit. p. 172 (1853) .... H. gutturalis.
