(200) Leptotila pallida Berl. & Tacz. 

 Leptotila pallida Bekl. & Tacz., P. Z. S., 1883, p. 575 (Chimbo, Ecuador). 



Found only in the Tropical Zone of the Pacific coast. This species has 

 hitherto been recorded only from western Ecuador whence we have seven 

 specimens. Comparison with a large series of L. rufaxilla from many lo- 

 calities shows no indication of intergradation with that form, the gray 

 hind-head and nape and (in view of its humid habitat) surprisingly pale 

 breast of pallida being constantly diagnostic.

(200a) Leptotila cassini Lawr. 

 Leptoptila cassini Lawr., Proc. Acad. N. S. Phila., 1867, p. 94 (Pananfa). 



Inhabits the forested lower Cauca-Magdalena region. Our specimens, 

 which agree with the type, considerably extend the range of this species 

 which appears not to have been before recorded from South America. 



Salaqui, 1 ; Opon, below Puerto Berrio, 1 ; Puerto Berrio, 2. 



(202) Osculatia purpurata Sak. 

 Oscvlatia purpurata Salv., Ibis, 1878, p. 448 (Ecuador). 



Apparently restricted to the Tropical Zone of the Pacific coast. Our 

 specimens extend the known range of this beautiful dove from Ecuador 

 northward to the headwaters of the Atrato. 



Although obviously the representative of Osculatia sapphirina of the 

 Tropical Zone at the eastern base of the Andes, the differences separating 

 these two forms seem to me to be now sufficiently pronounced and positive 

 to be considered of specific value.

(204) Oreopeleia montana (Linn.). 



Columbamontana'Lim!., Syst. Nat., I, 1758, p. 163 (Jamaica). 



Geotrygon montana Allen, Bull. A. M. N. H., XIII, 1900, p. 128 (Bonda). 



This wide-ranging dove inhabits both the Tropical and Subtropical 

 Zones and appears to be distributed throughout the greater part of humid 

 Colombia.
