Chameepetes goudotii and allies. 



With a series of sixteen speciineiis at my disposal it is 

 quite obvious that there are at least three, if not four, sub- 

 species ; these divide into geographical races by difference 

 of colour-plumage, and this is further supported in the 

 series by the measurements. Thus in the neighbourhood of 

 Bogota, which is the type-locality, the wing-measurement 

 ranges from 236-250 mm., the tail 215-238, and the tarsus 

 57-61 : in Antioquia, which is much farther north in 

 Colombia, the measurements are — wing 254-273 mm., tail 

 237-217, and tarsus 61-71; while in eastern Ecuador they 

 are — wing 245-262 mm , tail 237-251, and tarsus 65-84; 

 and two indivichuds from Peru liave the wing 242-243 mm., 

 tail 234—214, tarsus 79-80. The last two are sexed females, 

 so that the males would probably l)e even larger. These forms 

 may therefore be classed as follows : — 



Chamiepetes goudotii goudotii. Hah. District of Bogota^ 

 Colombia. 



Chanuepete^ goudotii antioquiana. Hab. Antioquia, N. 

 Colombia. 



Chamcepetes goudotii tschudii. Hab. Central northern 

 Peru and eastern Ecuador.

There arc four specimens in the British Museum from the 

 type-locality, Bogota, whicli measure — wing 236-250 mm. 

 and tail 215-238. It would appear therefore tliat this is tiie 

 smallest form of the group.
