Classificatory Reexamination on the Japanese Bats Contained within the so-called Siebold's Specimens Preserved in the Rijksmuseum van Natuurlijke Historie, Leiden

Abstract

Classifications of the Japanese bats (Table 1) contained within the socalled Siebold's specimens preserved in the Rijksmuseum van Natuurlijke Historie, Leiden were reexamined. On these specimens differences of classification, sex and adult or young between the descriptions in the catalogues of JENTINK (1887) and (1888) and the observations of the present author were summarized in Table 1, and the preserved conditions of these specimens were also added in this table. The main differences were as follows : The specimens of number 15 and 16, and also number 22 and 23 are distinct individuals respectively against JENTINK (1887) and (1888) . The number 26 labeled as “d” but unknown in JENTINK (1886), seems to be the skull of skin specimen of the number 25. The bat of number 21 is Nyctalus noctula from Europe, not N. lasiopterus from Japan. The number 22 is Nyctalus leisleri from Europe, not Pipistrellus abramus from Japan. The specimens of number 35 and 36 are Pipistrellus abramus from Japan, not P. pipistrellus from Japan.
