Abhandlungen der Koniglichen Akademie der Wissenschajlen 

 zu Berlin. Aus dem Jahre 1824. 4(o. Berlin. 1826. 



The Transactions of the Berlin Academy for 1824 offer only 

 three Papers on sul)jects connected with Zoology. Two of these 

 are from the pen of the celebrated anatomist Rudolphi ; and the 

 third is the production of M. Lichtenstein, the equally zealous 

 and active director of the noble Museum of Natural History, which 

 has, chiefly by his exertions and under his auspices, been formed 

 in that city, — a Museum of the value and extent of which the 

 Catalogue of the Zoological Duplicates, published by him a year 

 or two ago, forms a certain but necessarily far from adequate 

 criterion. 



The two papers contributed by M. Rudolphi are, as might be 

 imagined, entirely anatomical ; they both, however, relate to sub- 

 jects of general scientific interest. It would be superfluous, in the 

 brief notice which we can afford them, to enter into their details : 

 we shall, therefore, merely observe that the object of the first is 

 to furnish additional proofs in support of the now almost uni- 

 versally received opinion that the Orang-Otang differs from the 

 Pongo in nothing but in age ; and that the second contains an 

 account of the anatomy, more particularly of the nervous system 

 and electrical apparatus, of the Silurns electricus L., two fine 

 specimens of which, taken in the Nile, were sent home by MM. 

 Ehrenberg and Hempiich. Both papers are illustrated by ex- 

 cellent figures. 



Professor Lichtenstein's Paper " On the Antilopes of Northern 

 Africa, more particularly as regards the knowledge possessed of 

 them by the Ancients," contains full and minute descriptions, and 

 is accompanied with elegant representations of four species of this 

 beautiful and interesting group of Ruminants, with specimens of 

 which the Berlin Museum had been enriched by the exertions of 

 the same enterprising travellers. 'Yh^y ?iret\\e A. Leucoryx, A. 

 Dama, and A. Dorcas of Pallas, and a fourth which M. Lichtenstein 

 regards as new to modern science, but identical with the Strepsi' 

 ceros and Addax of Pliny, and to which he has assigned the spe- 

 cific name of Addax, the former synonym of Strepsiceros having
