E. A. and O. Bangs. Collected July 18, 1895, by C. H. Goldthwaite. 
Subspecific characters.— Size of Zapus h. canadensis ;? taillonger. Colors 
above darker, the dorsal band wider and not so sharply defined against color of 
sides; sides more intermixed with blackish hairs. Skull with brain case wider 
and higher; wider between orbits; audital bullz larger. 
Color.— Similar to that of Zapus h. canadensis, but rather darker above, the 
dorsal band wider, especially so on rump, and encroaching more on sides — 
not so sharply defined. Upper parts: a broad dorsal band, from nose to root 
of tail, brownish black lined with tawny ochraceous — the brownish-black- 
tipped hairs predominating; sides tawny ochraceous (the color of sides varies 
individually, from nearly raw sienna in some specimens, to nearly ochraceous 
rufous in others), thickly interspersed with brownish-black-tipped hairs; a 
narrow band of clear tawny ochraceous (sometimes inclined towards ochraceous 
rufous) along lower sides. Under parts white, often suffused with ochraceous 
or pale ochraceous rufous. Ears brownish black, sometimes narrowly bordered 
with dull ochraceous; feet and hands white; tail bicolored, dusky above, 
white below. 
Cranial characters.— The skull, compared with that of Z. 2. canadensis, is 
wider; the brain case is both wider and higher; the distance between orbits 
is greater; audital bulla considerably larger.
