Family PHYLLOSTOMIDAE 
This family, as represented in North America, includes bats having 
a simple noseleaf, a tragus, toes (except hallux) with three phalanges 
each, thumb and foot without sucking disk, and upper incisors not 
separated by a space in the middle. The only genus which has been 
found to occur in California is Macrotus, which is here represented 
by a single species.
