FAMILY TROCHILIDAE 283 



PHAEOCHROA CUVIERII CUVIERII (De Lattre and Bourcier) 



Trochilus Cuvierii De Lattre and Bourcier, Rev. Zool., vol. 9, September 

 (November) 1846, p. 310. ("isthme de Panama et Teleman, Amer. centr.," 

 restricted to east central Panama.) 



Characters. — Foreneck, upper breast, and sides lighter green ; lower 

 breast and abdomen paler. 



Measurements. — Males (13 from Canal Zone, eastern Province 

 of Panama, and San Bias), wing 67.1-71.6 (68.5), tail 39.6-42.7 

 (40.6), oilmen from base 22.0-25.5 (23.5) mm. 



Females (6 from Canal Zone and eastern Province of Panama), 

 wing 66.1-72.6 (67.6). tail 40.8-43.8 (42.5), culmen from base 

 23.8-25.8 (24.7) mm. 



Weight, 8 males, 9.30 ±0.24 grams; 4 females, 7.0, 7.5, 8.28, 9.0 

 grams (Hartman, Auk, 1954, p. 468. Though listed only as P. cuvierii 

 all are of the typical subspecies). 



Resident. Locally fairly common in the Canal Zone (Juan Mina, 

 Gatun), eastern Province of Panama (Pacora, La Jagua, Chepo, 

 Chiman), and San Bias (Mandinga, Perme). 



An adult male at Mandinga, shot from a high dead branch, Janu- 

 ary 22, 1957, may have been on a singing perch as described above 

 by Skutch in observations of this species in Costa Rica. According 

 to the original description cuvierii was described from a specimen 

 taken by A. De Lattre. The inclusion of Teleman, which is in eastern 

 Guatemala, in the localities cited obviously is in error as the humming- 

 bird of this general form in that area is Phaeochroa roberti, marked 

 by its wholly dark bill, which is considered to be a separate species 

 though some have treated it as a race. Available information indi- 

 cates that De Lattre made collections in Nicaragua, Panama, and 

 Peru. Under the travel routes of the period of his travels he would 

 have reached Panama either at Portobelo, Nombre de Dios, or 

 Panama City, so that it is appropriate to select east-central Panama 

 as a restricted type locality. 



PHAEOCHROA CUVIERII FURVESCENS Wetmore 



Phaeochroa cuvierii furvescens Wetmore, Proc. Biol. Soc. Washington, vol. 

 80, December 1, 1967, p. 230. (Zapotillo, 30 kilometers west of Sona, 

 Veraguas, Panama.) 



Characters. — Foreneck, breast, and sides darker green than in the 

 nominate race cuvierii, but not as dark as in saturatior of Isla Coiba ; 

 larger than cuvierii.
