part of the range of the subspecies in the vicinity of the type locality. 

 Maryland specimens are not so pale as typical hjsteri. 



Oranially the differences between the two subspecies are very slight. 

 T. s. lysteri averages somewhat smaller, and has relatively longer nasal 

 bones. 



Measuremsnts. — External measurements of five adults and cranial 

 measurements of four adults from Garrett and Allegany Counties, Md., 

 are as follows: Total length 233.4 (220-247); tail 87.8 (81-100); 

 zygomatic breadth 21.2 (19.9-22.2) ; postorbital breadth 10.9 (10.5- 

 11.2) ; length of nasals 13.5 (12.7-14.0) . 



Habitat amd habits. — Similar to T. s. fisheri. 



Specimens examined. — Allegany Comity: Dans Mountain (4 miles 

 northwest of Rawlings), 1. Garrett County: Bittinger, 1; Cunning- 

 ham Swamp, 1 (Coll. U. Md.) ; Finzel, 4; Grantsville, 1; Herrington 

 Manor, 1. 



Other records and reports. — Allegany County: Accident (Howell, 

 1929, p. 19). 



Remarks. — ^AU Maryland specimens assigned to this subspecies 

 represent intergrades between T. s. lysteri and T. s. fisheri in colora- 

 tion, size, and relative length of nasals, and assigning them to lysteri 

 is somewhat arbitrary. Specimens from Fallston, Harford County, are 

 also intergrades but are closer to fisheri and have been assigned herein 

 to that subspecies. 



WOODCHUCK 



Marmota monax tnonax (Linnaeus) 



[Mus'] monax Linnaeus, Syst. nat., ed. 10, 1 : 60, 1758. 

 Type locality. — ^Maryland. 



General distribution. — Middle eastern United States from Pennsylvania, New 

 Jersey, Ohio, Indiana, Illinois, Lower Peninsula of Michigan, and Iowa, south 

 to Arkansas and the northern parts of Alabama, Georgia, and South Carolina. 



Distribution in Maryland. — Abundant in all sections except the 

 Eastern Shore, where it has until lately been unknown. There is recent 

 evidence, however, that the species is extending its range into that 

 section. 



Distinguishing characteristics. — Teeth 1/1, 0/0, 2/1, 3/3, = 22; the 

 heaviest member of the squirrel family found within the State (weight 

 5 to 12 lbs.); tail short and somewhat bushy; fur thick and coarse; 

 coloration above grizzled brown, with top of head, face, legs, and 

 tail dark brown to blackish brown; under parts lighter in coloration, 

 and pelage not so thick; incisor teeth white; ears short and rounded. 



The large size, grizzled brownish coloration, and short bushy tail 

 readily distinguish this animal from any other rodent in Maryland.
