eut. The rauge of color variability of the Red Bat of the Carolin- 

 ian fauua never approaclies the character of that seen in all my speci- 

 mens from Tarpon Springs. They fully deserve sub-specilic recog- 

 nition, not only on account ot their decided differences, but because 

 of their constancy.

 Tarpon Springs, Fla., Dec. 24, 1893, col. 1)y W. S. Dickinson. 



Description. — Size two- thirds that of Scalops aquaticus ; pelage

 depth greater. Orbits relatively larger. Foramen magnum, viewed 

 posteriorly, ovate, regular, lacking tricrenate anterior outline always 

 present in adult aquaticus. In parvus there is a post-palatal spur not

 profile descending behind much more abruptly than in aquaticus, in
