In the preceding article on L. cmligena, I have given the 

 chief characters of the two species, which apparently make it 

 requisite that they should be separated ; and by conferring 

 upon this one a distinctive appellation, both are rescued from 

 the great confusion now existing in their synonymy, and 

 ornithologists are enabled to distinguish without difficulty 

 which form may be before them. The present bird is sent 

 to Europe in great numbers from Bogota — in fact, is one of 

 the commonest species of Humming-birds. Lesson^s species, 

 on the contrary, is by no means so generally met with ; and 

 as they bear a resemblance to each ot]ier,this may be the reason 

 that the two have been confounded together under his name, 

 especially if the accuracy of his plate has been viewed with dis- 

 trust. In order to avoid further difficulty in the recognition 

 of this species, I append a description of it, which, when 

 compared with that given above of L. cceligena, will enable 

 any one to ascertain the differences between the two birds.

 a rufous reflection ; back same as head, slightly darker in 

 colour ; rump (viewed from behind) brilliant metallic green.
