such a separation of the Carinate Birds; but it is not easily 
carried out. Where are the Caprimulgidae to be lodged ? and 
what is to become of the Steganopodes ? Doubtless one of 
these days such difficulties may be got over; but that happy 
time seems as yet far off, and for the present we are content 
to prefer the “ anatomical ” (which we trust we shall offend 
none by declaring to be the true “ zoological ”) method to the 
so-called “ physiological.” In the hope that this notice may 
meet the eye of Signor Savi, though our pages seem to have 
been unknown to his father, we may suggest his inserting in 
page 435, line 20, the words “ Savi* *s Warbler”—that being 
the name given by British ornithologists to one of their most 
valued treasures, to the history of which they have contributed 
not a little; and we can assure him on our own testimony that 
there is no doubt as to the parasitic habits of Oxylophusglan- 
darius ( cf . Ibis, 1859, p. 316). Apropos of Prof. Savi and 
Italian ornithology, we may remark that there seems to have 
been an error, which was first pointed out by Dr. Salvadori 
(Fauna dHtalia : Uccelli, p. 76), in M. de Selys-Longchamp*s 
paper in this Journal some years ago : for “ Merle maritime” 
(Ibis, 1870, p. 452) we ought to read “Merlo montano.” 
Mr. Hume has recently published all the information he 
could rake together concerning the eggs and nests of Indian 
birds*. The object of the volume is to give information to 
his numerous correspondents as to the extent of his know¬ 
ledge on these subjects, in order that they may supplement it 
by further observations and discoveries. 
‘The Birds of Great Britain* being now completed, Mr. 
Gould is turning his strength on to ‘ The Birds of Asia* 
on the 12th of March, 1850. There can be no doubt of the inventor of 
of the names “ Hesthogenous ” (!) and “ Gymnogenous ” having then 
conferred them on the two groups of birds, unconscious that his u First 
Thoughts on the Physiological Classification of Birds ” had already oc¬ 
curred to the eminent Swedish naturalist above mentioned.
