Birds of the Genus Pleroglossus. 267 



on the upper neck, and its sides blending into the dark sea 

 green of the back, wings, tail, and its terminal covers ; the 

 wings when closed measure four inches eight lines in extreme 

 length and are rounded, the quills blackish-brown externally 

 margined with olive green; rump and upper tail covers crimson ; 

 tail five inches long, colour of the quills and much cuneated, 

 the outermost feather on each side being only one inch and 

 three quarters long. Sides of the head, ear-feathers, and fore- 

 part of the neck dark chesnut, divided from the red band 

 which reaches to the middle of the body by a narrow crescent- 

 shaped band of yellow on the upper margin of which the 

 feathers are tipt with black, lower half of the body, vent, and 

 under tail covers yellow, the points of some of these last 

 feathers tinged with red. Flank and thighs olivaceous green, 

 legs dark green, claws brownish black. 



This bird was sold at the lamentable dispersion of the noble 

 museum of Mr. Bullock. It is evidently not quite arrived at 

 its full brilliancy of plumage, but sufficiently so to enable its 

 being described with perfect safety ; it was stated to come 

 from the French colonies in South America, and is the only 

 specimen I have yet seen ; the colours of the bill had preserved 

 tolerably well ; I have little doubt of its being the female bird, 

 for in many of the Aracaris, the only difference that exists 

 between the sexes is in the colour of the throat, which in the 

 male is black, in the female chestnut, whereas, in the genuine 

 toucans, the size (not the colour) of the bill I have always 

 found to be a constant discrimination.
