Type locality. — Trieste, Austria-Hungary. 



Geographical distribution. — Mediterranean region and eastward 

 into Asia. 



Diatjnoms. — Size about as in Pipistrellus natlmsii (forearm, 31 

 to 35 mm.; condylobasal length of skull, 12-0 to 13-2 mm.); 

 outer upper incisor less than half as high as inner incisor ; large 

 upper premolar almost or (}uite in contact with canine, the small 

 premolar forced inward from tooth-row and scarcely or not visible 

 from outer side, its greatest diameter about equal to that of 

 outer incisor ; canines less robust than in P. pipistrellHs, less 

 slender than in P.natluisii ; tragus with greatest width less than 

 length of anterior border ; thumb short, its length about equal to 

 width of wrist ; posterior edge of wing membrane with sharply 

 defined whitish border. 



External eharacters. — General form very similar to that of 

 Pipistrellus pipistrellus, the wing similarly narrow as compared 

 with that of P. natlmsii. Ear narrowly rounded at tip, the posterior 

 border slightly concave ; antitragus slightly developed, producing 

 an evident break in contour of conch ; inner surface of conch 

 somewhat rugose, without well defined transverse striations ; 

 tragus essentially as in P. natlmsii, the posterior border noticeably 

 convex. Wing, foot, calcar and tail as in P. p>ip)istrellus. 



Fur and colour. — Quality and distribution of fur essentially 

 as in Pipistrellus pipjistrellus, but dorsal surface of interfemoral 

 membrane haired scarcely beyond basal third. Colour not very 

 different from that of Pipistrellus pipistrellus, but somewhat 

 lighter and more yellow, often approaching raw-siena. Mem- 

 branes blackish, the wing between foot and fifth finger with a 

 sharply defined very narrow (less than 1 mm.) nearly white 

 border. 



Skull. — The skull resembles that of Pipistrellus natlmsii in 

 size, but its form is even more robust than that of P. pipnstrellus. 

 Dorsal profile with very slight interorbital concavity and barely 

 perceptible convexity over middle of brain-case. Breadth of 

 brain-case about half greatest length of skull. Dorsal surface 

 of rostrum less rounded off" at sides than in P. pipistrellus and 

 P. natlmsii, but not .so much flattened as in P. savii. Narial 

 emargination more abruptly narrowed posteriorly than in the
