at Gatun, some three miles north of the historic Loma del Leon. 

 Other localities where he collected were Agua Clara, Mindi and Mt. 

 Hope, between Gatun and Colon; Toro Point, across the harbor from 

 the latter city, and Ft. Lorenzo on the sea front just west of the Zone 

 border. A few specimens were also secured at Tabernilla, almost half 

 way across the isthmus, and at Pedro Miguel and Miraflores, nearer to 

 Panama. 



While the ornithology of the Canal Zone is supposed to be pretty 

 well known, every large collection from the region contains a few 

 species not hitherto reported, and in view of the increased interest in 

 the country due to the opening of the canal it has seemed desirable 

 to add to my report on Mr. Jewel's collection the names of such other 

 species as have been recorded from the region, so that we may have a 

 complete list of the avifauna. In making this compilation, in addi- 

 tion to the papers above quoted, the "British Museum Catalogue of 

 Birds"; "Biologia Centrali- Americana" and Ridgway's "Birds of 

 l^orth and Middle America" have been consulted. It is possible that 

 a few of the species recorded do not occur in the Canal Zone, as in 

 some cases "Panama" has been understood as referring to the city 

 while it may have been intended to denote the isthmus in general. 



From the light that Dr. Frank M. Chapman has thrown upon the 

 distribution of neotropical bird life in his "Distribution of Bird Life in 

 Colombia" we now recognize the importance of what he terms "the 

 Panama fault" and realize that many species are absent from the 

 Canal Zone and its immediate vicinity which occur in the mountains 

 of Chiriqui to the west and in the highlands of eastern Panama. As 

 Chapman has shown, the subtropical and higher life zones are entirely 

 lacking in the lower country of the Canal Zone, so that only the trop- 

 ical fauna remains; subtropical species, therefore, which are usually 

 quoted as occurring from Costa Rica to Ecuador have a gap in their 

 range coextensive with the low ground of the isthmus. 



In the list which follows the species not contained in the Jewel 

 collection are placed in their proper sj'stematic position, but have 

 their numbers enclosed in brackets. North American migrants are 

 marked with an asterisk.
