and then of the species of the Birds of Mexico and Central 

 America. The list of species, especially among the Passeres, 

 has been already augmented by the energetic ornithologists 

 of the United States, and a few more forms may yet remain 

 to be discovered. But the present work on the Avifauna of 

 Central America, as described by the authors, will ever 

 constitute a standing monument of their industry and muni- 

 ficence, and has now, after a long period of hard work, been 

 brought to a successful conclusion, forming one of the most 

 carefully prepared and well-executed bird-books of the present 

 epoch. 



It must also be recollected that the " Birds ". are but a 

 fragment of the great work of which the four volumes form 

 a portion, the ' Biologia/ with its twenty volumes, embracing 

 nearly every branch of the terrestrial fauna, besides Botany 

 and Antiquities.
