The bat genus _Pteronotus_ renamed _Dermonotus_

Vol. XIV, pp. 177-178 September 25. 1901 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON iER,, GENERAL NOTES. The bat genus Pteronotus renamed Dermonotus. In lsl.5, Rafinesqup, in his 'Analyse de la Nature' (p. 54), substituted Pteronotus in place of Pteropvti, apparently simply because he did not like the latter name. Of course there was no justification for such a procedure and Pteronotiifi is apure synonym of Ptrropus. Nevertheless, the name was given and consequently its use for another genus precluded. However, (iray gave the same name in 1S:]8 to agenus of Phyllostomoid bats, not knowing of its previous use by Rafinesque. As no other has been given to exactly the same type, anew one must be substituted and Dermonotus is appropriate, referring to the extension of the skin of the wings and interfemoral membrane upon the back. Those mammalogists who rank Pteronotus and f'hilont/rteris as sections of one comprehensive genus for which the latter name has been used will be more reconciled to the change when they consider that aless serious one will be entailed. It has been generally overlooked that Pteronotus was published ayear earlier than f'/rilonyrteris (1838 instead of 1839) and consetiuently that name would have to be used instead of C/iiloni/rterts, generally employed for the genus. An examination of the types of the two genera has led me to believe that the two groups should be regarded as generically distinct, if current views as to generic differentiation are to be adopted. —T/ieodore Gill.
