184 RBPOKX— 1880. 



Vespenigo velatus, Is. Geoff. 

 Add Bolivia to the localities of this species. 



Vespen^go serotinus, Schreb. 



Considering the gi'eat variability of specimens of this species, which 

 are occasionally found to vary more even in the same region than speci- 

 mens collected in very distinct zoological regions many thousands of miles 

 apart (for instance, specimens of the Serotine from Central America 

 have been found by me to present not the very least difference vyhen 

 compared with European examples), I am led to believe that the speci- 

 mens from Yunan described by me under the name of V. andersoni 

 (' Proc. As. Soc. Beng.' 1871, p. 211) represent but a variety or perhaps 

 local race only of this species. 



To the synomymy also add Vespertilio incisivus, serotinus et palustris, 

 Crespon, ' Faune meridionale,' p. 11 (1844), (vide Trouessart, ' Bull. Soc. 

 des Sci. Nat.' Nimes, fevr. 1879, p. 35) ; and for the variety, V. fuscus, 

 add the locality Folsom, El Dorado, California. 



Vesperugo borealis, Nills. 



Vegj'crvgo borealis, Dobson, ' Scientific Eesults of the Second Yarkand Mission,' 



—Mammalia, p. 12 (1879). 



To the description of this species (as given by me in the ' Catal. 

 Chiropt. Br. Mus.') may be added that a fringe of fine straight hairs 

 extends round the upper lip in front beneath the nostrils. This character 

 affords, in the case of badly preserved skins of immature specimens, an 

 easy method of distinguishing V. borealis from V. discolor, in which this 

 fringe is quite absent. 



Vesperugo maurus, Bias. 



In a paper, of which I have only recently been made aware by Dr. 

 Forsyth Major,' the identity of Vespertilio savii, Bonap. Vespertilio bona- 

 partii, Savi, and Vesperugo maurus, Bias, has been demonstrated to the 

 satisfaction of the author and of others, but as the types of the first two 

 named species are not forthcoming, and as the descriptions are incorrect 

 or insufficient, I retain Blasius' name. 



In the collection of the Gottingen Museum, I have lately found a 

 specimen perfectly indistinguishable from this species, which was carefully 

 labelled as having been sent from Popayan, in New Granada, in 1844, by 

 Degenhardt. The presence of a single specimen is, of course, not sufficient 

 ground to extend the distribution of this species to the Neotropical Region, 

 the Chiroptera of which (with one exception only — Vesperugo serotinus, as 

 I have shown ^) are quite distinct from those of any of the zoological 

 regions of the Eastern Hemisphere. There are, however, in the same 

 collection, several other specimens of species, evidently Neotropical, which 

 are labelled ' Popayan' (to be referred to hereafter), and with which this 

 specimen agrees precisely in the state of preservation. It is also note- 

 worthy that V. 7naurus has been found in Europe at very high elevations 

 only, along the Alps, and in this respect the South Amertcan habitat given
