differences, and the characters given for its distinction are 

 certainly not borne out by birds from the localities cited. 



The habitat of the species therefore, as at present known, 

 is Ecuador, Colombia, and Central America, from Panama 

 to southern Nicaragua. 



I notice that Dr. Hartert (Nov. Zool. v. p. 504) men- 

 tions that the wings of the two birds obtained at Paramba, 

 Ecuador, measured 340-355 mm., and that the bird from 

 Central America is larger, the head paler, and the pale mar- . 

 gins to the feathers broader. I have measured the wings 

 of four individuals from Central America and find the 

 average to be 361 mm., and two from Colombia, one from 

 Merida, Venezuela, and one from Ecuador, which average 

 355 mm., so that the diflerence is but slight. As regards the 

 colour of the head, 1 should say that the southern bird is 

 the darker of tiie two, but the difference is not great, and 

 I fail to see that the pale margins to the feathers of the 

 northern bird are any broader than in the southern species. 

 I do not altogether disparage the suggestion that these 

 may be subspecific forms, but the small amount of material 

 to hand is not sufficient to prove it.

No. 1966, Rio Perene, Junin, Peru, 800 metres, 24 March, 

 1900. Native name " Pavo." " Iris coftee-browu ; skin 

 round the eye blue-black; throat-patch red and bill red : 

 feet black'' (P. O.Simons). 



The bird collected by Simons is very similar to others in 

 the British Museum from Ecuador and Peru, among which 

 there is an example from the Rio Solimoens, whence the 

 original type of this species was obtained by Spix.
