the recorded ranges of the species, and Elliott remarks that “d/fwon 
benncttii, sometimes included in the North American launa, does not 
appear to be recorded north of the Isthmus of Panama.” The basis for 
the erroneous record seems to have been the inclusion of the descrijttion 
of Vampijr-us axiricularis, the type of which really came from Brazil, by 
Haussnre in his ” Notesnr qnelques INIammiferes dn Mexique,”t Sanssure’s 
species being later identilied with Mimon hennettii (Gray) by Peters.§ 
Comparison with a snbadnlt specimen from Ypanema, .Sao Paulo, J’razil, 
which has been determined by Oldlield Thomas and is assumed to represent 
typical Mimon bennettii, seems to show that Mimon cozwnelie is a fairly 
well-marked species. 
Specimens examined. —Eight, from the type locality (seven topotj'pes in
