(205) Oreopeleia veraguensis (Lawr.). 



Geotrygon veraguensis Lawh., Ann. Lye. Nat. Hist. N. Y., VIII, 1866, p. 349 

 (Veragua). 



Geotrygon veraguensis cachaviensis Habt., Nov. Zool., V, 1898, p. 604 (Cachabi, 

 Ecuador); IX, 1903, p. 603; Hellm., P. Z. S., 1911, p. 1206 (Noanamd). 



Not uncommon in the Tropical Zone of the Pacific coast and lower Cauca 

 River. Comparison of our sixteen specimens (of which five from Barbacoas 

 may be considered as topotypical of cachaviensis) with the type and three 

 Costa Rican specimens of veraguensis confirms Hartert's suspicion (Nov. 

 Zool. 1898, p. 603) that his cachaviensis is not separable; Colombian birds 

 average mbre purple above, anteriorly, and darker below, but the difference 

 is bridged by individual variation. (Females of this species have the fore- 

 head and flanks decidedly browner than in the male).

(206) Oreopeleia bourcieri (Bonap.). 



Geotrygon bourcieri Bonap., Consp. Av., II, 1854, p. 71 (Valle Lloa, Ecuador); 

 Hellm., P. Z. S., 1911, p. 1206 (Pueblo Rico). 



Not uncommon in the Subtropical Zone of the Western and Central 

 Andes, ranging upward to the lower border of the Temperate Zone, but like 

 all terrestrial forest birds diflScult to secure. Specimens from the Central 

 Andes average more vinaceous below and more cinnamomeus above than 

 those from the Western Andes, and thus show a slight approach toward 0. 

 linearis linearis of the Eastern Andes. This fact, in connection with the 

 evident absence of bourcieri in that range of mountains suggests the con- 

 clusion that linearis is a widely differentiated representative of bourderi, 

 but this theory is disproven by the capture of a perfectly typical specimen of 

 linearis at Puerto Valdivia, on the west shore of the Cauca River in Antio- 

 quia. This species is also recorded from Santa Elena in the Central Andes, 

 near Medellin, by Sclater and Salvin. 



It is somewhat surprising to find that our series of bourcieri from the 

 Western Andes, rather than those from the Central Andes, agrees with Ecua- 

 dor specimens. Of the latter I have six specimens from Zaruma in souther.n 

 Ecuador, and one from Chunchi (alt. 7200 ft.) and a trade skin labelled 

 "Ambato". All but the last agree with the west Colombian form, while
