BIRDS OF NORTH AND MIDDLE AMERICA. 



387 



pale olive-yellowish or whitish; chest indistinctly streaked with pale 

 olive-greenish and pale olive-yellowish or whitish; bill blackish; legs 

 and feet dull red in life, brownish in dried skins; length (skins), 99.8- 

 119.4(113); wing, 59.4^64.5 (61.7); tail, 32.5-3Y.8 (35.1); exposed 

 culmen, 15-18.5 (17); tarsus, 13-15.5 (14.7); middle toe, 9.7-11.7 

 (10.7).' 



^Nineteen specimens, from Middle America. 



After careful comparison of all the material available I am unable to discover any 

 appreciable or constant difference between South American and Middle American 

 examples of this species, except that specimens from the coast of northern South 

 America (Venezuela to Santa Marta, Colombia) have very long bills, and may consti- 

 tute a fairly well-marked subspecies G. c. brevipes (Cabanis). It is possible that a 

 satisfactory division may be made based upon females, as claimed by Mr. Oberholser 

 (Auk, xvi, 1899, 33), but after careful examination of specimens which, however, 

 are very inadequate, I am compelled for the present to forego any attempt at 

 such division. If any form is to be separated it seems to me that the Cuban birds 

 should be thus distinguished, for the few females from that island which I have 

 seen appear to be considerably paler and more uniform in color beneath than any 

 others.
