Principal records. DeKay : "The marsh meadow mouse is not un- 

 common in various parts of the state. I have seen specimens from 

 Oneida, Seneca and Otsego counties" ( '42, p. 85 under Arvicola riparius). 

 " It occurs in various parts of the state " ( '42, p. 88 under Arvicola 

 Jiirsutus). " This species is common in the western part of the state. My 

 specimens were obtained from the neighborhood of Oneida lake " ( '42, 

 p. 89, under Arvicola oneidd). " This meadow-mouse is found in various 

 parts of the state" ('42, p. 90 under Arvicola xanthognathus). 



Merriam : "The meadow mouse is common in the cleared lands 

 within and around the Adirondack region. It occurs on many of the 

 beaver meadows, but is never abundant in the coniferous forests " 

 ('8 4 d, p. 174). 



Fisher : " Very common in the low wet meadows especially near 

 streams " ( '96, p. 198). 



Mearns : " Specimens were taken from fields bordering Schoharie 

 creek (altitude 1700 feet) and on the ridge of Hunter mountain at an 

 altitude of 3900 feet" ('98, p. 348). 



I have found the meadow mouse abundant at Geneva, Ontario co. 

 Peterboro, Madison co. and Elizabethtown, Essex co. 



Mr Savage reports the species abundant in Erie co. Mr Helme writes, 

 " This animal is found quite plentifully in the upland fields of Long 

 Island, but is more abundant around the marshes and salt meadows." 



jRemarks. Although the meadow mouse is popularly considered one of 

 the worst farm pests, Mr Samuel N. Rhoads has recently published a 

 lengthy vindication of the animal ('98 a, p. 143-44 and '98 b, p. 571-81).
