Measurements. —Average of five adult males from Minnesota: Total 
length, 548; tail vertebrae, 143; hind foot, 83. Skull: Adult male 
(type): Condylo-basal lengtti, 87.2; zygomatic breath, 64.7; breadth of 
rostrum, 18.7. 
Remarks. —The range of this form includes the southern parts of Alin- 
nesota, Wisconsin, Michigan, and Ontario, and the greater part of New 
Aork Htate. The animal is intermediate in size between monax and 
canadensis and difi'ers from both in color and cranial characters. 
Marmota monax preblorum* suhsp. nov. 
NEW ENGLAND WOODCHUCK. 
Type from AVilmington, Mass. Adult male. No. 78,360, U. S. National 
Museum (Biological Survey Collection); April 19, 1896, A. E. Preble; 
original number, 127. 
Characters. Size medium (smaller than rufescens, larger than cana¬ 
densis)', colors pale (redder than monax, hut red not so dark as in 
canadensis or rufescens)', skull smaller and relatively narrower than that 
of rufescens, especially the rostrum and inter-orbital region. 
Measurements.—Adult male (type): Total length, 560; tail vertebrae, 
149; hind foot, 80. Skull (type): Condylo-basal length, 85.3; zygomatic 
breadth, 57.4; breadth of rostrum, 18.5. 
Remarks.—The woodchuck of southern New England is noticeably 
smaller and paler than rufescens, and larger and paler beneath than 
canadensis. Its skull is much larger than that of canadensis. It ranges 
from Connecticut north to Rutland, Vermont and Ossipee, New Hamp¬ 
shire, and probably farther, but material is lacking from northern New 
England to determine its exact limits. 
Marmota flaviventer parvula suhsp. nov.

miles north of Belmont). Adult female. No. 93,690, U. S. National IMu-

number, 6495. 
Characters. —Similar to M. f. ava,ra, but smaller, and colors darker; 
similar in color to flaviventer from the southern Sierra of California, but 
colors less reddish and npperparts overlaid with a bufiy mantle; similar

rowed at the tip , smaller than that of engelhardti with narrower and less 
inflated bullae.

130 ; hind foot, 70. Skitll (type): Condylo-basal length, 71.3; zygomatic
