cole: AVES from YUCATAN 145 



48.4 mm. The identification of this specimen is certain, as a description was 

 made at the time, and feathers from various parts of the bird were brought 

 liome for comparison. Just where the bird came horn is not so certain, but as 

 nearly as I could learn, it came from somewhere in the interior of Yucatan. 

 It is unfortunate that this could not be determined more definitely, as the spe- 

 cies appears not to have been previously reported from the peninsula, though 

 it is known to occur to the southward in Guatemala and Honduras.
