402 Bibliographical Notices. 



P.S. — T have now seen the type of Lichtensteln's H. oh- 

 scurus, which has been most kindly entrusted to Prof. Newton 

 for my use by Prof. Mobius, the Director of the Royal Zoolo- 

 gical Collection at Berlin, and the opinion above expressed 

 and arrived at some months since as to its distinctness from 

 the true Certhia ohscura of Gmelin and Latham (with the 

 type of which 1 have compared it) has been fully confirmed. 

 1 therefore confidently name it H. Lichtensteinij sp. n. 

 Prof. Mobius has also had the goodness to transmit two speci- 

 mens of '"'' Hemignathus procerus^ Cab. n. spec." I am not 

 aware of any published description of this species ; but the 

 specimens sent seem to be immature males of that which I 

 have above called H. Stejnegeri.
