484 Ornithological Literature of 1870. 



introduced is 23, and the number of species described as new is 

 288 ; lastly, the number of species figured is 270, in addition 

 to which numerous plates illustrating the anatomy, nests, and 

 eggs of many species have been published. 



In conclusion we must add that this article can only be con- 

 sidered approximately complete ; for it has frequently happened 

 that v/orks and papers have reached this country so long after 

 the date of their issue that their insertion has been unavoidably 

 omitted. 



As we are going to press, two parts of M. Alphonse Milne- 

 Edwards's important work, ' Oiseaux Fossiles de la France,' 

 containing livraisons 31-38, have reached us. These all bear 

 date 1870 ; but our abstract of them must be postponed to next 

 year. 



The length of the last article having forced us to exceed con- 

 siderably our prescribed limits, we regret to be obliged to defer 

 printing the communications sent us by numerous correspon- 

 dents till the next number of this Journal.
