miles’ distance from each other, would be sufficient to make us 
very doubtful of the possibility of their belonging to the same 
species. And, as for C. glabricollis , M. Des Murs seems to 
have forgotten that it was in Veragua , northwards of the 
Isthmus of Panama, where this remarkable bird was discovered 
by the indefatigable Warscewitz. But there can be no doubt 
that the three Cephalopteri are quite distinct species in the 
ordinary acceptation of the term, though closely allied, and, as 
is often the case in similar instances, representatives of each 
other in different zoological regions. 
In the sixth number of the f Revue/ M. Taczanowski gives 
an interesting account of his observations on the nesting of 
Parus pendulinus as noticed in Poland in the woody marshes on 
the banks of the Vistula. M. Moquin-Tandon continues his 
“ Notes Ornithologiques ” upon the birds of the South of France 
in the 7th number. 
The first part of M. Malherbe’s ‘Monographic des Pics’ has 
been issued, and gives us every reason to believe that the high 
expectations we had formed of its value as a scientific work will 
not be disappointed. The plates are well executed, and will 
leave no difficulty in recognizing the species of Picidce for the 
future. We are not yet, however, converts to M. Malherbe’s 
plan of altering established generic names, so as to make them 
terminate in ce picus ” or “picoides” and we had almost hoped that 
the author would have abandoned this part of his scheme, seeing 
the little favour it has met with amongst his brother naturalists. 
III. German, Dutch, and Russian Publications. 
Among the articles in the first two parts of Cabanis’ ‘Journal 
fur Ornithologie,’ we have already noticed Dr. Hartlaub’s 
“ Monographie der Glanzstaare.” Dr. Bernstein’s notes upon 
the edible-birds’-nest-making Swifts ( Collocalia :)* of Java, and 
* Several attempts have been lately made to clear up the somewhat 
complicated synonymy of the species of Collocalia —compare Moore, Cat. 
Mus. E. I. H. vol. i. p. 98; Cassin, Zool. U. S. Expl. Exp. p. 183, and 
Bonaparte, Compt. Rend. xli. p. 976. Dr. Bernstein has already con¬ 
clusively shown that this genus of birds belongs to the Swifts ( Cypselidce), 
and not to the Swallows. See Yerh. Kais. Leopold. Ak. Nat. 1857, p. 15.
