mens, procured by M. Harm and, enabled M. Oustalet to dis¬ 
tinguish the species from Ibis papillosa. These differences 
are pointed out, and the species referred to the genus Ge- 
ronticus under the name G. harmandi. Figures of these ap¬ 
parently fine novelties would be very acceptable.

The following letters, addressed “ To the Editors of ‘ The 
Ibis/ 55 have been received :— 
Sirs, —Permit me, in the cause of scientific exactness, to

(J. A. S. B. 1845, p. 601). Mr. Blyth may have been in
