 caught in May. Runny fusctftes assim-

 the February trapping site This is 

 the first record of R t. tn.unillis in 

 this area despite heavy trapping dur- 

 ing February and March, However, 

 fox scats collected from here in 

 February contained R I. us\inillis

The study area has many features 

 in common with Ihc part of the 

 KndlRikO State Park. N S W.. where 

 Cnlabv and Wimbush <lMf>4| col- 

 lected \fa\mcomys. The altitude and 

 vegetation of both arc similar. The 

 -tarn diiTetcncc is the lc*s sheltered 



environment and absence of perm- 

 ancntlv running creeks in the Falls 

 Creek.' habilat. Nevertheless, at the 

 [atta site many small boggy areas, 

 remain wet even in summer. Possibly 

 the MdffeKWWJW in tflB habitat move 

 In higher and drier ground with 1he 

 approach of winter. Tins may apply 

 ,iNo to R. i. tissiniilh. 



I his new record of Mii\uic<nny.\ 

 extends its dislrihution in Victoria, 

 and. lessens the gap between Victorian 

 ; md New South Wales populations. 

 The distribution of the species is not 

 as discontinuous as previously thought. 

 Probably Ihcsc distribution gaps will 

 be tilled by further field work.
