dunes between Port Chester and Mineral Springs stations of the Chi- 

 cago, Lake Shore and South Bend Railway. The nearest previous rec- 

 ords appear to be Newton and Starke counties'. It was caught in a 

 trap baited with bacon on the night of October 26 when the minimum 

 temperature was 47° F. The minimum temperature on the nights of 

 October 21 and 22 was 26° F. On the intervening nights the minima 

 were 50°, 52° and 50° F. These mice apparently do not hibernate with 

 the first freezing weather. 



Franklin Ground-Squirrel, or Spermophile, Citellus frankltm 

 (Sabine). Two specimens from Walkerton, southwestern corner of St. 

 Joseph County given to me by Dr. Matthew S. Denaut of Walkerton, 

 one in September and the other in October, 1923. One is a skin and 

 skull in the National Museum and the other a living specimen in the 

 National Zoological Park. This species appears to be extending its range 

 eastward. In 1908 Hahn' recorded it from Jasper, White, Newton and 

 Porter counties, in the later from the southeast corner. Agriculturists 

 about Walkei'ton state that the species is not common enough to be of 

 economic importance.
