BODEN KLOSS: Rats and Mice. [UT 
Specimens examined: A male and female from Olee Lheue (Oleleh) Atjeh, 
collected on 22nd September 1916 (Co-types: Nos.22 & 21); two males and two females 
from Meureudoe (Marudu) Atjeh, North Coast of Sumatra; and a female from Wlingi 
near Blitar, East Java. 
As these specimens were obtained for a plague Commission it is probable that 
they were all caught in houses. 
For skull measurements see table p. 118. 
Hind-feet of co-types; © 33, 9 32 mm, 
Remarks: Though in some individuals the basi-occipital suture is 
practically obliterated and the teeth are well worn I do not think that any 
of them are fully adult: but | have no doubt of their distinctness since they 
have been compared with examples of G. b. bengalensis of similar size 
and age. 
The principal differences between Bandicota GRAY, and Gunomys 
THOS., shown by this material seem to be: 
Gunomys. 
Skull a trifle broader; 
breadth to length index 55—60. 
Mamme 12 (?) to 18. 
Tail averaging proportionately a 
little shorter; less than .8 of head 
and body. 
Palatal foramina more contracted 
posteriorly so that their outer bor- 
ders form sigmoid curves. 
Bandicota 
Skull a trifle narrower; 
breadth to length index 53—56. 
Mamme 12. 
Tail averaging proportionately a 
little longer; more than .8 of head 
and body. 
Palatal foramina less contracted post- 
eriorly so that their outer borders 
are only slightly convex. 
The differences seem hardly of generic importance.
