Volans (Vespertilio). H. Allen, Proc. Acad. Kat. Sci. Phila., p. 282, 

 1866. TespertiUo volans H. Allen is another of the numerous syno- 

 nyms of Myotis calif ornicus. The name was based on a specimen from 

 Cape St. Lucas, Lower California. 



Yumanensis (Vespertilio). H. Allen, Monogr. Am. Bats, p. 58, 1864. 

 Myotis yumanensis of H. Allen is the small, large-footed bat, to wliich 

 the same author a few years later applied the name macropus, and 

 filially in his second Monograph regarded as identical with Myotis 

 albescens (Geoffroy). 



In a paper published in the Proceedings of the Philadelphia Acad- 

 emy of Natural Sciences for 186G, Dr. Allen gives a revised description 

 of M. yumanensis, based on a Fort Yuma specimen not mentioned in 

 the original account of the species. Tliis specimen was ^1/. caUfornicuSy 

 as shown by the very small hind foot whicli measured only two lines, 

 or 4.2 mm., about half as mucli as the foot of M. yumanensis. 



LISTS OF NORTH AMERICAN ArESPERTILl ONID^. 



Forty-six species and subspecies of Yespertilionida' are here recog- 

 nized as occurring in America noi th of Panama and in the West Indies. 

 This number will i)robably be materially increased when the^^est Indian 

 and Central American species are better known, and when adequate 

 series of skins from the mainland permit the definition of certain geo- 

 graphic races which doubtless exist but whose characters can not be 

 determined from the material now in collections. The North American 

 forms now known, with the names used for them by Harrison Allen in 

 1864, Dobson in 1878 and Harrison Allen in 1893, are as follows:
