352 I'ROCICEDINiiS OF THE NJT/OiY.lJ. Ml'SEUM. 



ARCTOMYS MONAX (Linnaeus). 

 WOODCIIUCK; GROUNDHOG. 



This species, tlie larjiest of tUe eastern iScinridd; is tolerably coin- 

 iiioii ill the Schoharie V^ alley. Its burrows were frciiueiitly seen in all 

 of the cultivated lands, thoujih I saw but one woodchuck. 



TAMIAS STRIATUS LYSTERI (Richardson). 



NORTHERN CHIPMUNK. 



Thechii)munk of the Schoharie Valley is distinctly of the lysteri type. 

 It was common, but shy, occurrinj;' from the edge of the creek (altitude 

 1,700 feet) up to the summit of Hunter Mountain (altitude 4,025 feet). 

 At Palenville, on the Hudson lliver side of the Catskills, intermediates 

 between the forms striatns and li/steri occur; in the Hudson Highlands 

 a few individuals from the highest elevations verge toward lysteri ; 

 lower down the Hudson Valley only true titriatus is found. No differ- 

 ence was detected between specimens collected in spruce iorests and 

 balsam sw^amps on the mountains and those from the fields and fences 

 along Schoharie Creek. All are lysteri and intermediate between the 

 typical form of the subspecies and the pale, yeHownsh ])hase found in 

 Maine. The specimens collected had fed most extensively upon mush- 

 rooms, wild cherries, and a small bulbous plant, probably a sedge. 

 More than one-half were affected by a subcutaneous jjarasite {Cutere- 

 bra) embedded in the cervical, abdominal, or inguinal region. A few 

 individuals of Per<))iiysciis were likewise affected by this parasite. 

 Forty-nine specimens of this chipnumk were preserved.

 SOUTHERN CHICKAREE OR RED SQUIRREL. 



This lively inhabitant of the forest was found at all altitudes, its 

 range extending from sea level to the highest peaks of the Catskills.

 specimens waue collected; one killed on August 15 was still partly in 

 winter pelage.
