458 Recent Ornithological Publications. 



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 ' 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 genei'ic names, so as to make them 

 terminate m " 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 

 fiir Ornithologie,' we have already noticed Dr. Hartlaub's 

 " Monographic 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 tlie somewhat 

 complicated sj^nonymy of the species of CoUocalia — 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 {Cypselidcs), 

 and not to the Swallows. See Yerh. Kais. Leopold. Ak. Nat. 1857, p. 15.
