Description

I originally thought it was an Antrozous pallidus (Pallid Bat), but the ears aren't long enough. The overall bat size is a bit too big to be a local myotis species. Any thoughts on the ID?
Here are my observations about its physical characteristics:
Head and body 66 mm
Tail 33 mm
Nose to tail 99 mm
No keeled calcar
No "free-tail", tail extends to tip of membrane
Forearm length 2-1/4 inch
Ears 20 mm
Flat, forward-pointing ears. Not pointed at the end.
Pointed tragus
No fringe
No hair on feet
No nose leaf
Nostrils forward-facing
Nostrils distinct but maybe not "pig-like".
Dorsal fur: pale at roots, tipped brown
Ventral fur: white
No yellow colors
Light-colored ears and face
Found dead, no "white nose" fungus observed.
My student Hailey Williams brought this in. She has several bats roosting in her neighborhood.
NOTE: My measurements weren't exactly lined up in the photos (also, the wing was not fully stretched out).

Description from Wikipedia

Bats are flying mammals in the order Chiroptera (pronounced /kaɪˈrɒptərə/). The forelimbs of bats are webbed and developed as wings, making them the only mammals naturally capable of true and sustained flight. By contrast, other mammals said to fly, such as flying squirrels, gliding possums and colugos, glide rather than fly, and only for short distances. Bats do not flap their entire forelimbs, like birds, but instead flap their spread out digits, which are very long...
