hibife the splendor of the natural colours by means 

 of powder or shell-gold impressed on the plates. 

 It must be confessed that it has not succeeded in 

 all instances so completely as might be wished. 

 The work however is extremely valuable, not only 

 as containing good figures of the major part of 

 established species, but also of numerous varieties, 

 and is preceded by an elaborate and ingenious 

 disquisition relative to the structure of the feathers 

 and many other particulars.

This is beyond comparison the most brilliant of 

 all the curve-billed Humming-Birds, its magnitude 

 ias well as colours giving it a decided superiority

 size of its body, but if measured from the tip of 

 the bill to the end of the two middle or long tail- 

 feathers, its extent is from eight to ten inches.
