Vesperugo noctula, Schreb. 



To the localities of this species add Hakodate, Yesso, Japan (Hilgen- 

 dorf and Peters) . 



Vesperugo vagans, 



Vesperugo vagans, Dobson, ' Ann. Mag. Nat. Hist.' Aug. 1879, p. 135, 



Bars short, triangular, like those of V. pipistrellus ; the tragus reaches 

 its greatest width in the upper third, inner margin slightly concave above, 

 outer margin straight in lower two-thirds, with a small rounded lobule 

 at the base not succeeded by an emargination, upper margin broadly 

 rounded oflF, in general outline, on the whole, like that of V. maurus. 



Post-calcaneal lobule well developed ; the rudimentary last caudal 

 vertebra alone projecting. Fur above, dark reddish-brown ; beneath 

 similar, but paler at the extremities. The membranes are nearly naked. 



Upper incisors like those of V. temminclcii ; the inner incisor on each 

 side moderately long and unicuspidate, the outer veiy short and conical, 

 scarcely exceeding the cingulum of the inner incisor in vertical extent, 

 but nearly equal to that tooth in cross-section at the base ; lower incisors 

 nearly at right angles to the direction of the jaws, trifid and crowded ; 

 first upper premolar extremely small, with difficulty seen even with the 

 aid of a lens, in the inner angle between the closely approximated canine 

 and second premolar. 



Length (of the type, an adult female) : head and body 2"'0, tail 1"'8, 

 head 0".65, ear 0"-5, tragus 0"-2, forearm l"-55, thumb 0"-3, third finger 

 (metacarp. l''"45, 1st ph. 0"'6, 2nd ph. 0"'75) ; fifth finger (metacarp. 

 1"-13, 1st ph. 0"-35, 2nd ph. 0"-36), tibia 0"-6, foot 0"-38. 



Type in the collection of the British Museum. Hab. uncertain, from 

 some part of the North American continent or from the West Indies. 

 Mr. Matthew Jones sent the specimen to the British Museum in the same 

 bottle with some fishes and other specimens collected at Bermuda, but he 

 informed me (during my visit to him at Halifax, N.S.) that he could not 

 say where the bat in qviestion was obtained. 



During my visit to Bermuda, I went over Mr. Bartram's collection, 

 and found only specimens of Afalapha cinerea and of Vesperugo iioctiva- 

 gans, which he assured me were the only species of bat ever obtained in 

 the island. 



Vesperugo ahramus, Temm. 



Vespertilio akohomuli, Temminck (Monogr. 'Mammal.' ii. p.' 223, pi. 57, 

 figs. 8, 9), was accidentally omitted in the list of synonyms of this species 

 (' Catal. Chiropt. B. M.' p. 226), although given as such in my ' Notes 

 on Dr, Severtzoffs Mammals of Turkestan ' (' Ann. Mag. Nat. Hist.' 

 1876, p. 130). Dr. Jentink has called attention to this omission in ' Notes 

 from the Leyden Museum,' ii. pp. 37-40 (1879). 



Signor B. Regalia has published some interesting notes • on this 

 species, recorded from Italy by Dr. Forsyth Major, in which he discusses 

 the relative values of the characters used to distinguish it from V. pipis- 

 trellus. 



Dr. B. L. Trouessart has lately ^ recorded the capture, by M. Lataste, 

 of a specimen of this species at Cadillac, Gironde, hitherto unknown west
