 Rhoads, Tarpon Springs, Hernando Co., Florida. Col. by W. S. Dickinson, 

 July 12, 1892. 



Description. — Somewhat smaller than A. borealis with a relatively 

 larger foot. Body colors above, from crown to tip of tail, including 

 ears, feet, interfemoral membrane and hairy spaces at upper base of 

 pollex and on proximal upper margins of the fifth metacarpal, uni- 

 form, cinnamon- brown, sparingly and minutely tipped with ash on 

 the cervical, dorsal, aud anterior interfemoral regions. Forehead, 

 cheeks, and chin, yellowish- brown. Throat, neck, and breast, like 

 back but more strongly tipped with ash. Abdomen like chin; hairy 

 lower surfaces of wings cinnamon along sides of body, fading to 

 orange- brown at the bases of metacarpals. Ear membranes dark 

 brown, postbrachial membranes but slightly darker than in borealis, 

 the antebrachial decidedly darker; interfemoral membrane nearly 

 naked above on the distal third, the inferior hairy space at root of 

 tail being less extensive than in borealis. Basal half of body hairs 

 sooty, the light interspaces occupying one- fourth, the cinnamon band 

 and ashy tip the remainder. 



Measurements. — Total length, 95 mm. ; tail vertebrse, 40 ; hind foot, 

 10: — (average of 3 adults — length, 90; tail, 43; foot, 10: average 

 of five A borealis — length, 100; tail, 50; foot, 8.5). Skull of type — 

 Naso- occipital length, 11.2; zygomatic width, 9.2; postpalatal notch

It has long been known that specimens of the Red Bat from 

 Florida were unusually dark colored but it was supposed that this was

 Tarpon Springs, in my collection, all show the same peculiarities of 

 coloration, and, in a recent paper, 1 I referred them doubtfully to A. 

 pfeifferi of Cuba, not having specimens of the Cuban form for com-
