the Nearctic Region, Dr. Jacobi divides it into two halves, 

 assigning the northern half to Arctogsea and the southern to 

 Neogsea under the hybrid name of the "Neoboreal Region." 

 This would not tend to simplify matters, as we should thus 

 find ourselves burdened with Tyrannidse, Trochilidse, and 

 other purely Neogsean forms in Arctogsea. 



Besides his chart of general distribution, the author gives 

 us a second chart to illustrate the localities of the species of 

 Jays [Garrulus) and Bullfinches {Pyrrhula) . 



133. Le Souef on the Birds of the Riverina District of New 

 South Wales. 



[A Visit to the Riverina District, New Soutli Wales. By D. Le Souef. 

 C.M.Z.S. Victorian Naturalist, xvii. No. 10, 1901.] 



Mr. Le Souef sends us a sketch of the bird-life of the 

 Riverina District of New South Wales in a season when a 

 copious rainfall had completely filled the Murray River and 

 its adjacent lagoons. This event induced a large number 

 of Ibises and other water-loving birds to resort there for 

 breeding-purposes. A colony of Straw-necked Ibises was 

 estimated to consist of at least 200,000 individuals. Spoon- 

 bills, Herons of several species. Cormorants, Ducks, Geese, 

 Avocets, Stilts, and Cranes were likewise found nesting in 

 the same district.

Ilerr v. Lorenz contributes the ornithological portion to a 

 history of the progress of Zoology in Austria and Hungary 

 during the last fifty years. He divides this space of time 

 into decennial periods, and reviews shortly the principal 

 publicatioijs relating to Ornithology issued during each of 

 them, sorting these according to the localities to which 

 they refer and other subjects. The predominant figure 

 in Ornithology in Austria during the past fifty years has
