A further advance in our understanding of the fossil Odonata, 

 due to Haxdlirsch, is in placing the Mesozoic forms in genera 

 distinct and separate from those to which they had been referred 

 previously. Their previous positions, as summed up in Kirby's 

 Catalogue of 1890, gave the false impression that many of our 

 living genera reached backward to the Jurassic. 



Faunal Studies. 



Time and space forbid us to do more than mention the larger 

 and more comprehensive papers or scries of papers which have 

 appeared in this division of the subject. The general distribu- 

 tion of Odonata throughout the world was summarised b\- 

 Carpenter in 1897. Lucas (1900) has given us a volume on 

 British Dragonflies, Tümpel has included the central European 

 species in his Geradflügler Mitteleuropas (iSgS-icjoo), and Fröh- 

 lich {1903) has produced a work of similar scope for German\', 

 and KoHAUT (1896) for Hungary. Rossler (1900), Dzied- 

 ziELEWicz (1902), PusCHNiG (1905-1908), and Strobl and 

 Klapalek (1906) have treated in considerable detail of the 

 Odonate fauna of various parts of the Austrian Empire. For 

 Italy are the memoirs of Garbini (1897) and Bentivoglio 

 {1897-1908). Navas (1905-1910) has furnished much informa- 

 tion for the Iberian peninsula, while the dragonflies of Russia, 

 Siberia, and other parts of Pakearctic Asia are receiving atten- 

 tion from Bartenef (1908-1912), whose papers, being in the 

 Russian language, are unfortunately sealed to most of us. Peter- 

 sen (1905-10) is the principal worker on the Scandinavian repre- 

 sentatives of the Order. 



For the Oriental region we have the series by Krüger on 

 Die Odonaten von Sumatra (1898-1902), and papers h\ Foerster 

 (1896-1905), Karsch (1900), Laidlaw (1902-1907). Williamson 

 (1904, 1907), Morton (1907), and Xkkdham (1909) on otlier 

 subdivisions. 



The Ethiopian region has attracted uuuii attention, .md there 

 are many memoirs by de Selvs (1896-8), Calvert (1896-8), 

 Karsch (1896, 1899), Kirby (1896, 1900, 1909), Förster (1897- 

 1909), Sjöstedt (189g), Martin (1900-08) and Grünberg 

 (1 902-1 903).
