Zapus insignis Miller. 



Woodland Jumping Mouse. 

 Pirate 20, Fig. i. 



Length 9.80 inches. Larger than the meadow species, less 

 dusky above, sides inclining to rich orange, underparts snowy- 

 white, tail with a distinct white tip. Molar teeth only three on 

 each side, while in the other species there are four. 



This is a larger edition of the preceding, restricted to the cold 

 boreal forests, though from its small size it can often exist 

 where larger animals have been compelled to retreat owing to the 

 depredations of the woodsmen. 



This jumping mouse was only made known to science in 1891 

 by Mr. G. S. Miller, Jr., who discovered it in New Brunswick. 

 To that indefatigable field naturalist, Samuel N. Rhoads, we are 

 indebted for adding it to the fauna of New Jersey. In May, 

 1893, he secured four specimens in woods bordering Lake Hopat- 

 cong, near Nolan's Point (Proc. Acad. Nat. Sciences Phila., 

 1897, p. 29). These are now in the collection of the Philadelphia 

 Academy. 



The species, doubtless, occurs at other points in the northern 

 tier of counties.
