_Specimens examined_ (14).--1/2 mi. W Reva, 1; 10 mi. S, 5 mi. W Reva,
12; 7 mi. S, 4-1/2 mi. E Harding, 1.
This vole evidently is limited in Harding County to habitats of dense
grass and forbs adjacent to water. We failed to trap the species in some
areas that appeared to be suitable for occupancy.
Two females, collected on May 15 and June 2, contained three and six
embryos, respectively, that measured 15. One female with five placental
scars (May 15) and two with six (May 16, June 2) also were trapped, and
a lactating female was captured on June 20. Testes of two adult males
taken in spring (May 18 and June 2) measured 15, and those of one
weighing 45.6 grams that was taken early in June measured 17.
