 Total length, 235 ; tail vertebrae, 95 ; hind foot, 32. 



Geographic distribution. Peninsular Florida, north to southern Georgia ; 

 exact western limits of range unknown. 



Habitat. The hammocks and margins, where there is plenty of live 

 oak and water oak; nocturnal, spending the day in hollow stumps or in 

 nests in the thick bunches of Spanish moss. 



General characters. Very similar to S. volans t>/picus, from which it 

 differs in having the upper parts more uniform russet, and the under 

 parts, especially the under surface of tail, strongly washed with the same 

 color; soles naked ; audital bullre wheel-shaped, very large and deep. 



Color. Upper parts russet, shading to yellowish drab in places ; cheeks 

 grayish white ; upper surface of feet and hands sooty gray ; toes rather 

 lighter; under parts white, a good deal shaded with pinkish russet. 

 Cranial characters. Skull similar to that of & volans, except that the 

 audital bullre are much larger, more inflated, and 

 broadly wheel-shaped (see figs. 31 and 32). Size 

 of an average adult skull (the type) : basilar 

 length, 30.2 ; occipitonasal length, 34.6 ; zygomatic 

 breadth, 21 ; greatest height of cranium above

General remarks. Sciuropterus volants querceti 

 passes into true volans in southern Georgia, a 

 series of specimens from St. Marys, Ga., being in 

 termediate between the two. A specimen from 

 Powhatan Plantation, near Gibson, La., without 

 a skull, seems referable to this form, and may thus 

 , extend its range tc the coast of Louisiana.
