Tiirdus sp.?, Tacz. P. Z. S. 187H, p. 2-21. 



Turdus maranonicus, Tacz. P. Z. t>. 1880, p. 189, pi. xx. 



General colour of the upper parts olive-brown, each feather 

 having an obscure dark margin (which may be the lemains of imma- 

 turity) ; median wing-coverts with pale tips of huffish brown (also 

 a sign of immaturity) ; lores and car-covcrts showing pale centres. 

 Ground-colour of the underparts pure white, slightly suffused with 

 buff on the throat and under wing-coverts ; axillaries, centre of 

 belly, and under tail-coverts purs white, the remainder of the 

 feathers of the underparts with dark-brown terminal spots, which 

 are fan-shaped on the chin and throat and halfmoon-shapcd ou the 

 breast and flanks ; inner margin of quills buff. Bill dark brown. 

 Wings with the fourth and fifth primaries nearly equal and longest, 

 second primary intermediate in length between the seventh and 

 eighth, bastard primary 1-1 to 1-0 inch. Legs, feet, and claws 

 brown. Length of wing 4'5o to 4-5 inches, tail 3"7o to 3"G2, 

 culraen 0-9 to 0-88, tarsus 1-2. 



It is not known that any difference of plumage is attributable to 

 sex or season. The bird described above is probably a male of the 

 year. Young in first plumnge are slightly more rufous in the 

 colour of the upper parts, and each feather has a buff shaft-line and 

 a dark-brown margin; the wing-coverts have fan-shaped terminal 

 buff spots. 



The Peruvian Thrush has only been obtained in the valley of 

 the Marauou, in Northern Peru, where it is supposed to be a 

 resident. 



The British Museum does not possess an example of this species. 

 The only skins known to exist are in the "Warsaw Museum, from 

 which the above descriptions are taken.
