This is tlic first of a series of six quarto volumes^ whicli 

 the accomplished Director of the Caucasian Museum at Tiflis 

 proposes to devote to tlie illustration and explanation of the 

 rich collections under his charge. The present volume 

 — printed in Russian with a German context — contains

 vi. p. 361.] 



In this important memoir IVlr. Rothschild has endeavoured 

 to give us the results of his great experience in the examina- 

 tion of specimens of the genus Apleryx, both alive and dead, 

 especially of those belonging to the unrivalled collection of 

 these birds which he has succeeded in bringing together. 

 Though we may regret that some of these results are not of 

 a rather more positive character, there can be no question 

 that JVIr. Rothschild's account of the species whicli he is able
