Genus ADELONYCTERIS H. Allen. 



Scotophilus Leach, Trans. Linn. Soc. London, xiii, 1822, 71. (Type, S. kuhlii.) 

 Vesperua" Keyserling &, Blasius, Wie<^m. Arch. 1839, "NVirbelthiere Europas, 1840, 49. 

 Adelonycteris H. Allen, Proc. Acad. Nat. Sci. Phila., 1892. 



Diagnosis. — As in the case of VespertiUo it is impossible to frame a 

 diagnosis of a genus where the forms are cosmopolitan and the student 

 is confined to material representing a fauna. I am content to designate 

 Adelonycteris by the dental formula. 



Dental formula. — Molars f, premolars i, canines |, incisors f x 2 =: 

 32 teeth. 



Vesperns was established on VespertiUo serotinus and VespertiUo dis- 

 color. It is distinguished from othe vespertilionine bats by the pres- 

 ence of a single molar in the upper jaw. The genus Scotophilus was 

 based by Leach on an individual without locality. For many years 

 English writers (especially Gray and Tomes) applied this name to the 

 forms now included under Vesperus and Vesper ugo. I followed the same 

 practice in the Monograph of 1864, since I naturally assumed that these 

 writers were acquainted with Leach's type. Peters in 18GG pointed out 

 the fact that Scotophilus was distinct and embraced a group of bats 

 none of whose representatives are found either in Europe or America. 

 Scotophilus, therefore, can be no longer applied to any of our species. I 

 have lately ascertained, through specimens in the possession of the 

 Museum of Comparative Zoology, that Scotophilus closely resembles 

 Atalapha, which genus it may be said to represent in Africa, Asia, and 

 Australia. 



Mr. F. W. True has called my attention to the fact that the Vesperus 

 of Keyserling and Blasius, 1840, is antedated by Vesperus of Dejean, 

 1821. The latter was a nomen nudum until 1829, when it was taken 



K. & B. propo.sed Vesperus as a subgenus to VespertiUo.
