BIRD LIFE IN THE URUBAMBA VALI.EY OF PERU. 71 



(1458) TROGONURUS COLLARIS COLLARIS (VIeillot). 



Trogon collaris Vieillot, Nouv. Diet. d'Hist. Nat., vol. 8, 1817, p. 330 (Cayenne). 



Appai-ently to be referred to this form rather than to virginalis of 

 M^estern Ecuador. The male has the white tail-bands even broader 

 than in one from eastern Ecuador, which in default of Cayenne 

 specimen I accept as representing collaris, but thefemale is more dusky 

 on the lores and auriculars than an east Ecuador bird, though not so 

 much so as in the west Ecuador bird. 



Rio Cosireni, 1 male, 1 female. 



(14G7) TROGONURUS BOLIVIANUS (Grant). 



Trogon bolivianus Grant, Cat. Birds Brit. Mus., 1890, vol. 17, p. 470, pi. 15 

 (Cosnipata, Peru). 



Our specunens confirm the validity of this species, and show that 

 it ranges at least from the Beni River in Bolivia to the base of the 

 eastern Andes in Colombia. Specimens from the Provinces of Co- 

 chabamba and Santa Cruz agree with a series from Chapada, Matto 

 Grosso, and evidently represent Trogonurus variegatus. Hellmayr •''° 

 recognizes the Bolivian form under the name Trogon variegatus heJini, 

 on the basis of larger size and shorter white tips to the outer rectrices, 

 but in the absence of topotypical specimens of variegatus I am unable 

 to say whether our Bolivian birds are separable. There can, how- 

 ever, bo no doubt of their distinctness from hoKvianus, which has 

 broader black and narrower white bands on the tail; the throat, and 

 breast largely or wholly purple, and with a narrower white band or 

 none at aU; and, as a rule, greener, less brassy back and bluer rectrices. 

 These characters are most highly developed in our Colombian birds, 

 but the Beni River specimen has less white in the tail than any other 

 in the series.

 River, 1 male, 1 female. Peru: Rio Tavara (long. 70° 20'; lat.
