354 BIRDS OF THE REPUBLIC OF PANAMA — PART 2 



Bangs (Proc. Biol. Soc. Washington, vol. 19, July 30, 1906, p. 106) 

 recorded that in "63 males, 33 have the throat violet and white mixed, 

 in some nearly half and half, and 30 have plain white throats." In 

 25 males in the U. S. National Museum 5 have the throat color a 

 mixture, in the others it is plain white. 



The eastern limit of this race may include the higher levels of the 

 mountains in extreme western Bocas del Toro near the Costa Rican 

 boundary, an area where the birds are as yet unknown. The inclusion 

 of cinereicauda from the Volcan de Chiriqui in Ridgway (U. S. Nat. 

 Mus. Bull. 50, pt. 5, 1911, p. 507), quoted uncertainly from this 

 source by later authors, was in error. I find no reference in Ridgway's 

 manuscripts, or in the sources that he had available, in verification.

 (Gould) 



Trochihts ( ?) castaneoventris Gould, Proc. Zool. Soc. London, pt. 18, 



1850 (February 28, 1851), p. 163. (Volcan de Chiriqui, at 1,800 meters, 

 Chiriqui, Panama.) 



Orcopyra leucaspis Gould, Proc. Zool. Soc. London, pt. 28, August 1860, p. 312. 

 (Volcan de Chiriqui, 2,750-3,000 meters, Chiriqui, Panama.) 



Characters. — Male, in normal phase, throat white, rarely with this 

 area violet-purple ; tail black to bluish black ; breast darker gray than 

 in cinereicauda. 



Female, darker, more rufous on lower surface than in calolaema or 

 cinereicauda ; central rectrices dark metallic green to slightly bronze- 

 green. 



Viewed with a strong light coming from behind, the throat in males 

 shows a light pink reflection. In a number that I have examined there 

 is a faint tinge of violet along the lower edge and at the sides of the 

 gorget, and occasionally a violet feather is found along the side or 

 even farther out among the white feathers. While in the typical 

 white-throated individuals the feathers are white nearly to the base, 

 this may vary to those where the dark base color covers half or slightly 

 more of the feather. 



The definite reports known to me of males with purple throats from 

 the Volcan de Chiriqui are few. There is 1 in the U. S. National 

 Museum (no. 273939), marked "Boquete, Chiriqui, 3500 ft." without 

 other data, obtained from a dealer (not named), about 1923. The 

 appearance of the skin indicates preparation by Arce. Another, not 

 quite so well marked was taken by Dr. Frank Hartman, February 

 10, 1956, on Cerro Copete above Boquete. In the Monniche collection
