1911. It commences with a summary of the routes taken 

 by the three expeditions, and general remarks on the country 

 traversed and its inhabitants, which we are sure will be read 

 with pleasure by every ornithologist. After these general 

 remarks, which occupy some 70 pages, comes a general list 

 of the birds collected and observed during the expeditions. 

 These are 250 in number. But this part of the memoir can 

 be in no way treated as a mere " List." It contains full 

 remarks not only on the localities, but on the habits and 

 alliances of every one of the birds met with or observed 

 which nearly entitle it to be treated as a History of the 

 Birds of Algeria, and it certainly makes the best authority 

 on that subject yet in existence. 



The Avifaunas of Europe and Algeria resemble each other so 

 closelv that the student of the one easily becomes acquainted 

 with the facies of the other. There are, however, small and, 

 in some cases perhaps, almost imperceptible differences 

 between the European birds and their Algerian representatives 

 which can be realized by the skilful maker of subspecies. It 

 will be seen, on looking through the present volume, that 

 " trinomials '"" are plentifully used by the authors to designate 

 such cases. The forms of Algerian bird-life have been so 

 well provided with subspecific names by previous writers 

 that only two appear still to remain nameless — Col/vus 

 monedula c'trtensis and Galerida thekkv hilgerti. 



On the plates will be found illustrated two forms of 

 Merops persicus, three of Galerida thekhi:, and a number of 

 the heads of the various forms of Sparrow whose relation- 

 ships are somewhat complicated. Plates 15-26 contain 

 reproductions of photographs of Algerian scenes taken by 

 the two authors.

Count Salvadori revises the arrangement of the species 

 of the genus Conurus allied to Conurus aruyinosus, and 

 distinguishes eight species instead of four as given in
