A. SHORT NOTE ON THE INDIAN RATS. 



11 



three stripes are very narrow and are not supplemented by an 

 ill-defined lower pair ; this form may be found in houses where the 

 domestic form (the palm squirrel) does not exist. 



Throughout this pamphlet my endeavour has been to keep 

 the language simple and free from technicalities ; accordingly there 

 have been no references to the history or literature of the subject; 

 no discussions on disputed points ; no mention of cranial measure- 

 ments. Those who wish for information on such points are referred 

 to my Memoir on the Rats of Calcutta, now being issued as part 

 of the first volume of the " Memoirs of the Indian Museum."
