remaining 34-toothed species. Each of these groups had been 
named by Kaup ten years previously. Therefore each of 
the constituent parts of the genus Vesperugo was provided 
with a tenable name at the time when the composite genus 
was formed. The first of the two genera into which the 
original subgenus Vesperugo is now divided is 
PIPISTRELLUS, Kaup, 1829. 
1829. Pipistrellus, Kaup, Skizzirte Entw -Gesch. u. natiirl. Syst. der 
europ. Thierw. Ister Theil, p. 98. Type Vespertilio pipistrellus, 
Schreber. 
1839. Vesperugo, Keyserling & Blasius, Wiegmann’s Archiv fiir 
Naturgeschichte, v. Bd. i. p. 312 (part.). 
1856. Nannugo, Kolenati, Allgem. deutsch. naturhist. Zeitg. Dresden, 
neue Folge, ii. pp. 181, 169-172. Based on Nathusit, pipistrellus, 
and Kuli. 
1856. Hypsugo, Kolenati, Allgem. deutsch. naturhist. Zeitg. Dresden, 
neue Folge, ii. pp. 131, 167-169. Included “ Vesperugo” maurus, 
Blasius, and “V.” Krascheninikovii, Eversmann. 
1878. Vesperugo, Dobson, Catal. Chiroptera Brit. Mus. p. 185 (part.). 
1893. Vesperugo, H. Allen, Monogr. Bats N. Am. p. 121. 
The type species, the Pipistrelle, is therefore 
Pipistrellus pipistrellus (Schreber). 
The second of the included genera is 
PTERYGISTES, Kaup, 1829. 
1829. Pterygistes, Kaup, Skizzirte Entw.-Gesch. u. natirl. Syst. der 
europ. Thierw. Ister Theil, pp. 99, 100. Type Vespertilio noctula,

geschichte, v. Bd. i. p. 312 (part.).

proterus and fulvus. 
1856. Panugo, Kolenati, Allgem. deutsch. naturhist. Zeitg. Dresden, 
neue Folge, ii. pp. 181, 172-174. Included noctuda and Leisleri. 
1878, Vesperugo, Dobson, Catal. Chiropt. Brit. Mus. p. 185 (part.). 
1893. Noctulinia, H. Allen, Proc. U.S. National Museum, p. 30. 
The type will stand as 
Pterygistes noctula (Schreber). 
III. The Genus Barbastella. 
In Dobson’s Catalogue of the Chiroptera in the British 
Museum the generic name Barbastellus is discarded in favour 
of Synotus, Keyserling and Blasius, 1839, on the ground that 
it was first applied to a spec-es of Nyctophilus *.
