FAMILY TROCHILIDAE 361 



chase, so that among them there was constant activity. As they moved 

 about, the small white spot immediately adjacent to the eye was so 

 prominent that it gave the curious impression of being the eye itself. 

 My only observation of this hummer elsewhere was of one in the 

 canyon of the Rio Chiriqui Viejo, at 1,750 meters below Cerro Punta. 



The population of this species found in Costa Rica and western 

 Chiriqui is definitely different from that from farther north. Related 

 subspecies range through Central America and Mexico to the moun- 

 tains of southern Arizona and southwestern New Mexico. It is inter- 

 esting that females in spectabilis have somewhat longer bills than 

 males, which is not the case in the populations recognized elsewhere 

 in the species fulgens. 



Zimmer (Amer. Mus. Nov., no. 1513, 1951, p. 3) combines the 

 genus Eugenes and several others with Heliodoxa, mainly on the basis 

 of the "long forward extension of the frontal feathering, covering 

 the nasal operculum, and an equal extension of the chin plumage." A 

 superficial similarity in this detail is obvious. But it should be noted 

 that in Heliodoxa leadbeateri, type of the genus Heliodoxa, the 

 operculum is covered with feathers while in Eugenes fulgens it is 

 bare. Until more information is available it seems preferable to retain 

 the two as separate genera. 



HAPLOPHAEDIA AURELIAE (Bourcier and Mulsant) : Green 

 Puff-Leg, Pantalon Bombacho Verde 



Trochilus Aureliae Bourcier and Mulsant, Ann. Sci. Phys. Nat. Agric. Ind., 

 Soc. Roy. Agric, Lyon, vol. 9, 1846, p. 315, pi. 10. (Bogota, Colombia.) 



Medium size ; green, with cinnamon upper tail coverts and black bill. 



Description. — Length 108-116 mm. With prominent large white 

 and buff feather tufts on the tibia. Adult male, green above, including 

 the outer primary coverts; more or less bronzy on the cheeks and 

 pileum ; upper tail coverts cinnamon ; tail blue-black ; wings dusky 

 with a purplish sheen ; foreneck, breast, sides, and under tail coverts 

 metallic green, the feathers tipped narrowly with grayish white; 

 abdomen grayish white; large tibial tufts pure white, mixed more or 

 less with buff ; under wing coverts metallic green. 



As a species this hummingbird is found in mountain areas from 

 Colombia south through Ecuador and Peru to north Bolivia, with 

 colonies on Cerro Pirre and Cerro Tacarcuna, in eastern Darien. Five 

 races have been recognized in the South American range, with two 

 additional in Panama. Zimmer (Amer. Mus. Nov. no. 1540, 1951, 

 p. 35) also includes Haplophaedia lugens (Gould) as a subspecific en-
