I have collected 9 specimens of Bandicoot, but these were out 
of a series of over 2,000 examined, = three of these were sent to s 
me from other districts than my ow ; 
The frequency of N. bengaleneie i is certainly overstated in the — 
above table, and the explanation is that my most noe collector — 
worked in a quarter where grain godowns aboun : 
tions in other districts, I should say that ha ‘all over = ia city 
Nesokia sebgse ae sis and M. decumanus are about equally frequent. 
IT hav oad generally indicated the reason for publishing 
this abstract. The preparation of the plates which are to accom 
pany the fall paper will take so long that it seems advisable not to 
wait indefinitely but to publish this rough summary at oft 
the hope that it may be of some use to those who are workin 
the connection between rats and plague.
