88. Oustalet on Birds from the Algerian Sahara. 



[Notice sur la Collection d'Oiseaux recueillie par M. Dybowski dans le 

 Sahara. Par E. Oustalet. Bull. Soc. Zool. France, xvi.'p. 59, 1891.] 



This memoir, which has hitherto escaped our notice, but of 

 which the author has recently sent us a copy, gives an account 

 of a collection made by M. Dybowski at Erg, in the Algerian 

 Sahara. It contained examples of 33 species, besides which 

 9 others were observed in life. There are no species addi- 

 tional to the Algerian list, but a dissertation on the Bird- 

 life of the Sahara follows, which is well worthy of perusal.

 generally understood that these energetic explorers, in spite 

 of the dangers and difficulties of their novel route, made and 

 carried home collections of natural history of the highest 

 interest to science. The series of birds collected by these 

 travellers has been carefully studied by M. Oustalet and forms 

 the subject of the present memoir. 



The route taken by the expedition was from Kuldja, which 

 was left in September 1889, over the Thian-Shan mountains 

 and down the Tarim river to Lob-nor. Hence in midwinter 

 the passage of the Altjn Tagh w'as effected and a descent 

 made in February 1880 on the Tengri-nor. After a bold 

 attempt to move south to Lhasa, the party then turned east- 

 ward to Tsiamdo, on the upper streams of the Mekong, and 

 passing Batang arrived at the French Missionary Station of
