 Diagnostic characters and description. — Size of P. lencopus, 

 but both young and adults are of a bright golden brown color above 

 and the under parts are yellowish instead of white. In addition to 

 these general color differences, this mouse is distinguished from 

 P. leucopus in having no distinct line of demarcation between the 

 color of the dorsal and ventral surfaces and in having the color of 

 back extending down the limbs to the feet. The ears are also 

 smaller, but there is no very striking difference in the skulls of the 

 two species. 



Range. — This species was first described from Norfolk, Virginia. 

 Its range extends along the Atlantic coast from Chesapeake Bay 

 to Florida and in the west to Missouri. It has never been recorded 

 from Indiana and certainly is not common in any part of the State. 

 However, it is not improbable that it will be found in the southwest 

 portion as it occurs in Illinois. 



Hahits. — Kennicott, who collected the species at several points 

 in southern Illinois, says that it is an inhal)itant of the forest, al- 

 though it is also found among the hazel thickets at the edge of the 

 prairie. He states that it builds its nest in the branches of small 

 trees and the tops of hazel bushes. The nests resemble those of birds, 

 but are roofed over and have a small opening on the side. It prob- 

 ably does not burrow, though its nest has been found under a log, 

 where it was made of fine bark and fibres and was placed on top 

 of the ground with no underground burrow leading to it. It is 

 strictly nocturnal in habit and its food consists of various kinds of 

 seeds and nuts. 



In the east it seems to frequent low ground and has been found 

 to be abundant in the Dismal Swamp.
