Measurements. -kxerage of five adult males from Minnesota: Total 

 length, 548; tail vertebrae, 143; hind foot, 83. Skull: Adnlt male 

 (type): Condylo-basal length, 87.2; zygomatic breath, 64.7; breadth of 



rostrum, 18.7. 



Reinarks.—The range of this form includes the southern parts of Mm- 

 nesota, Wisconsin, Michigan, and Ontario, and the greater part of New 

 York State. The animal is intermediate in size between monax and 

 canadensis and difl'ers from both in color and cranial characters. 



Marmota monax preblorum* subsp. nov. 



NEW ENGLAND WOODCHUCK. 



Type from Wilmington, 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, but 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 canademis. 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 subsp. nov. 



NEVADA MARMOT. 



Type from Jefferson, Nye Co., Nevada (in Toquima Range, about 10 

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

 seum (Biological Survey Collection); June 3, 1898, V. Bailey; original 

 number, 6495. 



Characters. — Similar to M. f. avara, but smaller, and colors darker; 

 similar in color to flaviventer from the southern Sierra of California, but 

 colors less reddish and upperparts overlaid with a huffy mantle; similar 

 to engelhardti, but smaller, the upperparts more buffy and underfur paler; 

 skull similar to that of avara, but decidedly smaller, with rostrum nar- 

 rowed at the tip ; smaller than that of engelhardti with narrower and less 

 inflated bullae. 



Measurements. — Adult female (type): Total length, 470; tail vertebrae, 

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

 breadth, 49; breadth of rostrum, 17.4. 



Remarks. — This is the smallest of the subspecies of flaviventer and the 

 * Named for Messrs. Edward A. and Alfred E. Preble.
