General remariks. — My oils lucifugus resembles 31. velifer more closely 

 than it does any other Xoith American species. From the latter it is, 

 however, readily distinguishable by its much smaller size. From M. 

 subulatus, the only species of the genus with which it is associated in 

 tlie eastern United States, it may be at once recognized by its shorter 

 ear and shorter, less acuminate tragus. 



This bat is the Vespertilio gryphm lucifugus of Dr. Harrison Allen's 

 recent monograph. Dr. Allen's 'northern form of Vespertilio gryphus'' 

 is M. suhulatus. 



Through the kindness of Mr. S. IsT. Ehoads I have examined the type 

 and six topotypes of Vespertilio lucifugus austroriparius from Tarpon 

 Springs, Fla. I can find no characters by which these specimens may 

 be distinguished from those taken at other i)arts of the range of Myotis 

 lucif ugus. The two skins, one of which is the type, are those of partly 

 grown individuals whose immaturity is clearly indicated by the soft, 

 papery skulls in which the nasal sutures are still clearly visible, and 

 by the imperfectly formed joints of the fingers (see fig. 1, p. 9). These 

 specimens differ from northern adults in smaller size, shorter fur, and 

 duller, browner color. Three adult toi)otypes in alcohol show only one 

 of these peculiarities — the shortness of fur — and in the fourth this also 

 IS absent. The fifth alcoholic si^ecimen is immature. That the adult 

 specimens of Myotis from Tarpon Springs are not smaller than J/, luci- 

 fugus from other localities is clearly shown by the table of measurements 

 on page 65. The short fur of three of the adults is evidently a seasonal 

 character, since all showing this i)eculiarity are in worn, ragged coat, 

 while the only one in fresh pelage (killed September 12) has fur of 

 the ordinary length. The fur of all these specimens, after nearly five 

 years immersion in alcohol, has lost the warm, glossy appearance char- 

 acteristic of freshly killed individuals. It can be perfectly matched, 

 however, among the series of alcoholic specimens collected in Center 

 County, Pa., daring the winter of 1893.
