THE FAMILIES. AND GENERA OP BATS. 6 



1777. Erxleben, Systema Regni Animalis. Two genera of bats are 

 recognized, Pteropus and Vespertilio, both placed in the Linneean 

 order Primates. 



1779. Blumenbach, Handbuch der Naturgeschichte. The Mammalia 

 are divided into 12 orders: I, Inermis; II, Pitheci; III, Bradypoda; 

 IV, Sclerodermata ; V, Chiroptera; VI, Glires; VII, Ferse; VIII, 

 Solidungua; IX, Bisulca; X, Belluse; XI, Palmatse, and XII, Cet- 

 acea (pp. 57-59). Vespertilio, with 5 species, is the only genus of 

 bats. 



1800. Cuvier, Lecons d'Anatomie Comparee. The Cheiropteres are 

 placed as a subdivision of the Carnivora. 



1806. Dumeril, Zoologie Analytique. The Mammalia are divided 

 into 14 families, the first three of which are Bimanes, Quadrumanes, 

 and Chiropteres. Six genera of bats are recognized. 



1808. Tiedemann, Zoologie. The bats form the " X Ordnung, Vogel- 

 artige Saugthiere, Fliegende Saugthiere, Chiroptera (Chiropteres, 

 Alipedes.)" There are 7 genera, one of which is Galeopithecus. 



1816. Oken, Lehrbuch der Naturgeschichte, dritter Theil, Zoologie. 

 The bats (17 genera) form the first division of " III Ordnung, 

 Vogelsuke— Klauer," thus : 



III Ordnung, Vogelsuke — Klauer. 



A. Haltklauer. 



1 S. Finkenklauer — Flere ; Fledermause. 



2 S. Rabenklauer — Tatzer. ; Spitzm., Igel. 



3 S. Spechtenklauer — Kraller ; Zahnerlose, Ameisenba- 



ren, Gurtelth., Schnabelth. 



B. Reissklauer. 



'4 S. Aukenklauer — Robben. 



5 S. Reiherklauer — like ; Marder. 



6 S. Hiihnerklauer — Koter ; Hunde, Katzen. 



7 S. Trappenklauer — Baren. 



1817. Cuvier, G., Le Regne Animal, I. In this work the " Cheirop- 

 teres ". form the first family of " Carnassiers." They are all placed 

 in the genus Vespertilio, but this is divided into two main groups, the 

 Rousettes {Pteropus) and the true bats. Among the latter, 12 sub- 

 divisions or subgenera are recognized. Essentially the same plan is 

 followed in the second edition, published in 1829. 



1820. Desmarest, Mammalogie. The classification is the same as 

 that of Cuvier : 



Ord. Carnassiers. 



Premiere Famille, Cheiropteres. 



Premiere Tribu, Galeopitheques. 

 Seconde Tribu, Chauve-souris. 

 The minor groups of the former author are, however, recognized 

 as 16 genera, while no less than 95 species are described.
