There are some interpolations in tMs series ; but not all those presented, as such in the 

 table are actually present. I make out 111 plates by actual count. They were executed by ' 

 Werner. 



The nomenclature is very lax, scarcely satisfying the requirements of a system. The 

 names in the text do not always correspond with those in the table, from which I have taken 

 the above list ; and the author's way of using names is difficult to make out, or see the point 

 of. Only Prench names are engraven on the plates. This laxity or carelessness is a serious 

 blemish upon an otherwise very praiseworthy and valuable monograph. There is about a 

 leaf of text, descriptive, etc., to each plate. 



' ' Many of the plates ai-e original, others are copied from Spix, Temminck, or Lear ; they 

 are executed on stone, and though inferior to the works of Gould and Lear, they are perhaps 

 the best ornithological lithographs which have issued from the French press. The text of 

 this work is prepared with considerable care, but the nomenclatiire wants precision, the latin 

 names being often wrongly spelled, and the principles of binomial nomenclature often departed 

 from. Thus the genus Palceornis is in one instance designated Psittaeus, in another Psiftacus 

 sagittifer, and in a third Conurus sagittifer, with the addition in each case of a specific name."
