ri^'er southward, leaving the Atrato, lower Cauca and Magdalena Valleys 

 as the home of tzmatl.

(1112) Amizilis tzacatl jucunda {Heine). 



Eranna jucunda Heine, J. f. O., XI, 1863, p. 188 (Babahoyo, Ecuador). 

 Amazilia riefferi, Simon & Dalm., Ornis, XI, 1901, p. 221 (Naranjo). 

 Amazilia tzacatl jucunda Hellm., P. Z. S., 1911, p. 1183 (R. Sipi; Noanamd; 

 N6vita). 



Tropical Zone of western Ecuador northward to the San Juan river in 

 Colombia. Western Ecuador specimens average larger; the males have the 

 abdomen tinged with rusty; females have this region paler than in tzacatl. 

 I can detect no diagnostic differences in the color of the upper mandible. 

 On the whole the Colombian birds are intergrades between tza/iatl and 

 jucunda and, as stated above, it is purely a matter of opinion where the line 

 bounding the ranges of the two forms be drawn.

(1119) Hylocharis grayi {Delatt. & Bourc).

 Hylocharis grayi Obbkh., Proc. U. S. N. M., XXIV, 1902, p. 317 (Patia Valley). 



Found in open and arid or semi-arid places at Caldas, in the Cauca 

 Valley up to the borders of forest, and southward through the Patia Valley 

 to northern Ecuador. It is apparently an arid-zone representative of H. 

 humboldti which inhabits the humid coastal region.

Eucephala humboldti Simon & Dalm., Ornis, XI, 1901, p. 219 (Buenaventura). 



Found in the Tropical Zone of the Pacific coast from at least Buena- 

 ventura southward. Females differ from those of H. grayi chiefly in having 

 the throat white, unspotted, the tail green.
