504 TINAMID^. 



bastard-wing, primar)'-coverts, and secondaries olive-rufous, with 

 irregular black bar-like marks ; under wing-coverts olive-buff, 

 with irregular black lines, the greater ones uniform greyish ; tail 

 olive-brown, with irregular black lines, and rufous-buff marks on 

 the outer web : bill dusky above, paler (olive ?) below ; feet in the 

 dry skin pale olive. Total length about 17 inches, wing 9'4, tail 

 3*75, culmen 1'25, tarsus 2-56. 



Female. Similar to the male, but somewhat larger, and whiter 

 below ; upper part of the head uniform rufous cinnamon ; no greyish 

 tinge on the forehead and sides of the head, which are uniform with 

 the pileum, only a shade lighter ; ear-coverts also rufous cinnamon ; 

 no conspicuous occipital crest ; fore neck and breast nearly uniform 

 greyish olive ; upper parts less marked with black ; secondaries 

 browner. Total length about 19 inches, wing 9-4, culmen 1-30, 

 tarsus 2-50. 



Eoth the birds described belong to batterer's collection and are 

 from Hio Negro : they have been attributed by von Pelzeln to two 

 different birds, the male to T. suhcristatus * and the female to 

 T. brasiliensis ; but they are so much alike that I cannot believe 

 that they are specifically different, as it would be impossible that 

 two such allied forms should be found in the same region ; the 

 differences appear to me to be only sexual. 



I am not quite certain as to the proper name of this species, the 

 description of the old authors being very unsatisfactory ; for the 

 present I have thought it best to retain the name major, although 

 it was applied to the bird from Cayenne, where I am not aware 

 that the species has been found in recent times. Marcgrave's and 

 Brisson's descriptions may apply to T. solitarius, to which I have no 

 doubt Pezus serratus, Spix, also belongs.
