314 BIRDS OF THE REPUBLIC OF PANAMA — PART 2 



of his association with Dow when he came to Panama to visit 

 McLeannan, Station Master at Lion Hill on the Panama Railroad. 

 The specimen described above as presented by Dow labeled "Costa 

 Rica" is identical in form and appearance with hummingbirds of 

 this same kind collected and prepared by McLeannan. It seems pos- 

 sible that this may have been its source. 



The bird is common in the Chagres Valley, and also wherever 

 there is forest shelter for it eastward through Darien and the 

 Comarca de San Bias. Beyond Panama it continues into the lower 

 Atrato Valley of Colombia in northern Choco (Acandi, Unguia), 

 and also on the eastern side of the Golfo de Darien in extreme 

 northern Antioquia. Its eastern limit is in the lower valley of the 

 Rio Sinu, as in the lower Cauca-Magdalena drainage beyond it is 

 replaced by nominate Damophila julie julie. The male of the latter 

 bird has the anterior half of the pileum bright, glittering green, but 

 otherwise is like panamensis. Ridgway (U. S. Nat. Mus. Bull. 50, 

 pt. 5, 1911, p. 520) recorded Damophila julie julie from Bugaba, 

 Chiriqui, but in this was misled by a specimen wrongly labeled. 

 Griscom in his work on Panama evidently did not examine this skin. 

 This is apparent from Peters' statement in a footnote under Damo- 

 phila j. panamensis (Check-list Birds World, vol. 5, 1945, p. 50) 

 where he says "Griscom informs me that the specimen from Chiriqui, 

 referred to D. j. julie by Ridgway, is an aberration of the present 

 form." Ridgway's source was U. S. National Museum catalog 

 no. 150788, purchased in a collection made by two missionaries, 

 H. Th. Heyde and Ernesto Lux. The bird, an adult male, is labeled 

 "Bugaba-Chiriqui," but is a well-marked example of Damophilia julie 

 feliciana (Lesson) of Ecuador. As the collection in which it was 

 received in addition to specimens from Panama included other hum- 

 mingbirds from Ecuador the locality on the label of the individual 

 under discussion certainly is erroneous. 



In view of the range given for D. j. panamensis in Colombia, it is 

 pertinent to remark that Ridgway's record of typical julie from 

 Turbo in northern Choco on the Gulf of Darien also is taken from 

 a specimen with questionable data. This is U. S. National Museum 

 number 17902, collected on the Michler Survey for a possible canal 

 route through the lower Atrato. The bird is cataloged as part of 

 the collection in question, but instead of the printed label of this 

 expedition, has a small tag marked Smithsonian Institution, with the 

 locality "Turbo. N. G. Schott" written by another hand. As the 

 naturalists in the party secured other hummingbirds at Cartagena
