266 Recent Ornithological Publications. 



Mr. Eyton has reprinted the osteological plates, thirteen in 

 number, which were given years ago in his ' Monograph of the 

 Anatidce ;' to these five new ones, representing the skeletons of 

 Cereopsis novce-hollandia, Dendrocygna arcuata, Biziura lobata ( 6 

 and $ ), and Erismatura aiistralis, are added, and the whole 

 published as a ' Supplement' to his great work on the osteology 

 of birds*, of which we have before announced the completion 

 (Ibis, 1868, pp. 98, 99). 



Mr. A. C. Smith has done well in adding to his pleasant 

 little book on Portugal f a chapter containing a reprint of his 

 paper on the birds of that country, which appeared in this 

 Journal (Ibis, 1868, pp. 428-460). He has further done well 

 in incorporating therewith a translation of the observations on, 

 and additions to, the same, made by Prof. Barboza du Bocage, 

 and lately mentioned by us [supra, p. 134), so that the whole 

 forms a useful epitome of what has hitherto been recorded with 

 respect to Portuguese ornithology. Mr. J. H. Gurney, how- 

 ever, informs us that be can add yet one other species to the 

 list — to wit, Buteo desertorum, of which he lately saw in the 

 Museum at Lille two specimens from Portugal, where its occur- 

 rence is a matter of probability ; for we believe that Mr. Howard 

 Saunders has obtained it in Spain. 



2. French. 

 We have already [antea, p. 122) alluded to the ingenious 

 experiments on the flight of birds by Prof. Marey of the College 

 de France, a full account of which, with the results at which he 

 arrived, is printed in the ' Revue des Cours Scientifiques' for 

 1869 (Nos. 37, 38, 41, and 44) ; and it now gives us much 

 pleasure to give a very brief abstract of his investigations. The 

 chief apparatus for showing the real character of the motions of 

 the wing consists of two air-tight basins [cuvettes), with tops of
