P.S.—I have now seen the type of Lichtenstein’s H. ob- 
scurus, Which has been most kindly entrusted to Prof. Newton 
for my use by Prof. Mébius, 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 obscura of Gmelin and Latham (with the 
type of which I have compared it) has been fully confirmed. 
I therefore confidently name it H. Lichtensteint, 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. Stejnegeré.

mented by this more elaborate work by himself and Canon Norman.
