THE FAMILIES AND GENERA OF BATS.

1777. Erxleben, Systema Regni Animalis. Two genera of bats are 
recognized, P ter opus and Vespertilio, both placed in the Linnsean 
order Primates. 
1779. Blumenbach, Handbuch der Naturgeschichte. The Mammalia 
are divided into 12 orders: I, Xnermis; II, Pitheci; III, Bradypoda; 
IV, Sclerodermata ; V, Chiroptera; VI, Glires; VII, Ferse; VIII, 
Solidungua; IX, Bisulca; X, Belluae; XI, Palmatse, and XII, Cet- 
acea (pp. 57-59). Vespertilio , with 5 species, is the only genus of 
bats. 
1800. Cuvier, Legons 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 G aleopit hecus. 
1816. Oken, Lehrbuch der Naturgeschichte, dritter Theil, Zoologie. 
The bats (17 genera) form the first division of “ III Ordnung, 
Vogelsuke — Khmer,” thus : 
III Ordnung, Vogelsuke — Klauer. 
A. Haltklauer. 
1 S. Finkenklauer — Flere; Fledermause. 
2 S. Rabenklauer — Tatzer. ; Spitzm., Igel. 
3 S. Spechtenklauer — Ivraller; Zahnerlose, Ameisenba- 
ren, Gurtelth., Schnabelth. 
B. Reissklauer. 
4 S. Aukenklauer— Robben. 
5 S. Reiherklauer — like ; Mar der. 
6 S. Huhnerklauer — 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 (P ter opus) 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.
