Nat. 



In this connection it may be said that J. B. Tyrrell (/. c.) has collected 

 this from as far north as the Hudson Bay. 49G1, M. C. Z. from Arkansas 

 is the most southern locality from which I have noticed it. The foot 

 in this specimen is very large, viz., 1'" long ; the base of toes are furnished 

 with long hairs, the tibia is 17'»'" long, and the external basal lobe of 

 the auricle is not incurved. 



Var. {b) Northern form of Vespertilio gryphus. 



It is highly probable that this variety has been repeatedly de- 

 scribed in numerous accounts of North American bats (see Appendix) - 

 but for the reasons already given it is impossible to determine to which 

 species of the earlier naturalists it should be assigned. It is found best 

 expressed in the region of which the St. Lawrence River is the center. 

 Sjiecimens have not been found north of Canada, south of New York, 

 iior west of Wisconsin. 



The tragus is long (truly subulate) directly outward. The anterior 

 border of the auricle is distinctly convex, the posterior border concave. 

 Ears long, next to V. albescens evotis in size. They reach beyond the 

 median line at mentum. The foot is small, scarcely one-third the 

 length of tibia. No post-calcaral lobe, but an apici-calcaral lobe is 

 well marked; the tip of the tail is exsert; the membranes are light- 

 brown in color.
