(lOOOo) Glaucis hirsuta afiinis Lawr. 



GlaiuAs affinis Lawk., Ann. Lyo. N. H. N. Y., VI, 1858, p. 261 (Napo, Ecuador). 

 Glaucis hirsuta Scl. &. Salv., P. Z. S., 1879, p. 528 (Sta. Elena). 



Inhabits the Tropical Zone at the eastern base of the Eastern Andes, 

 the Magdalena and Cauca Valleys, the lower Atrato Valley and eastern 

 Panama. The distribution of this species in Colombia agrees, therefore, 

 with that of those birds which evidently have entered the country from 

 Amazonia. (Compare, for example, that of Ostinops decumanus). 



After comparison of our Colombian specimens and thirteen from eastern 

 Panama (R. Tuyra; R. Capeti) with the type and a topotype of affinis, I 

 follow Ridgway in referring birds from the region outlined to that race. 



I have not, however, seen specimens of Glaucis hirsuta fusca Cory from 

 the southwest shores of Lake Maracaibo (Field Mus. Pub., 167, 1913, p. 286).

(1002) Glaucis senea Lawr. 



Glaucis ceneus Laws., Proo. Acad. N. S. Phila., 1867, p. 232 (Costa Rica). 

 Glaucis columhiana Bottcabd, Gen. Hum. Bds., 1895, p. 402 (Rio Dagua). 

 Glaucis hirsuta cenea Hellm., P. Z. S., 1911, p. 1178 (Guineo, R. Calima). 



Hellmayr (L c.) has already shown that this species occurs on the Pacific 

 coast of Colombia and in northwestern Ecuador, and comparison of eight 

 specimens from San Jose, Barbacoas, and Esmeraldas, with two from Costa 

 Rica (including the type) and four from Nicaragua, confirms his views. 

 The range of the species is not, however, as he surmised, continuous, and 

 although it inhabits the Tropical Zone, it appears to have a distribu- 

 tion similar to that of the large group of Subtropical Zone species which 

 are unknown between Costa Rica or western Panama and northwestern 

 Colombia. 



This fact, in connection with the occurrence of Glaucis hirsuta affinis in 

 eastern Panama (see above), and the differences in color between asnea and 

 hirsuta {cf. Ridgway, Bull. 50, V, p. 329) lead me to believe that these birds 

 are specifically distinct, as indeed Mr. Ridgway has aheady surmised 

 (Z. c). Aside from its more bronzy upperparts, our series confirms the state- 

 ment that in oenea the sexes are alike, the male as well as the female being 

 cinnamon below.
