PTEROGLOSSUS FRANTZH Cabanis. 



FRANTZItrS' ARAgARI. 



Adult (sexes alike). — Head and neck, all round, plain glossy black, 

 becoming more sooty on chin and upper throat; back and scapulars 

 glossy dark greenish oUve, separated from the black of hindneck by 



Three specimens from Yucatan with sex undetermined measure as follows: Wing, 

 135.5-140; tail, 134.5-149; culmen, 75.5-89.5; tarsus, 31-32; outer anterior toe, 

 26.5-27.5. There is the same great amoimt of individual variation in this form as in 

 P. t. torquatus, but as a rule the under parts are more extensively suffused with red 

 and there is usually less of black, this being sometimes practically wanting from the 

 abdominal band as well as from the breast.
