LÖNNBERG AND RENDAHL, ORNITHOLOGY OF ECUADOR. 23 



lection received from Buenos Aires. As we ha ve not been able 

 to convince ourselves about the identity of Lesson's type 

 mth our specimens, we have preferred to use Sclater's name. 

 Chubb has established a new subspecies Ä. gayi simonsi 

 for birds from the Titicaca Basin, Peru. This is said to be 

 mottled with grey instead of buff, and the marginal and sub- 

 marginal lines on the feathers of the fore-neck paler etc. With- 

 out discussing the validity of this subspecies we wish to draw 

 attention to the above stated facts, viz. that mottled and 

 banded feathers occur in the same bird, and that the colours 

 of the feathers are subjected to fading from buff to whitish, 

 as the feathers become older and more worn. 



Chubb has also said that his new race should be rather 

 larger than the Ättagis of Ecuador. The length of wing of the 

 Titicaca race is stated to be 189 mm. in the male, and 192 

 in the female, while Sclater's bird had this measurement 

 7,3 inch. or about 185 mm. This apparent difference in size 

 is, however, according to our experience of rather little value. 

 We base this opinion on the fact, that the specimens of the 

 present collection have with only odc exception larger wing- 

 measurements even than »simonsi)). The length of v^ing is 

 in the females from Pichincha from 193 to 197 mm., and m 

 the males resp. 186, 193 and 202 mm. Even if the last of 

 these by mistake should have been wrongly sexed, their supe- 

 liority is clear, but we consider this to be only individual 

 variation. 



Concerning the habits of the Attagis of Pichincha Consul 

 Söderström has communicated the foUowing. »These birds 

 are found outside the crater in coveys of from 3 to 7. They 

 fly very rapidly and feed on the seeds of a lupine named by 

 the natives »fraglejon», and also on green leaves of plants. 

 They nest among stones and sand. Eemale larger than male, 

 14 — 16 ounces. » 



Ptiloscelis resplendens Tschudi. — 2 males, 3 females, 

 July_Aug., Chaupicruz, 5 miles north of Quito, 9300—9450 

 f. 1 male 7, Chilogalla 3 miles south of Quito, 1 male '7, 

 slopes of Antisana, 11000 f. 



Oxyechus vociferus Lin. — 1 S 7i2 Grillo valley, at San 

 Pedro river, 8500 f.; c^ & $ '72 La Carolina. These are 

 evidently migrants.
