Alston, P. Z. S. L. 1877, p. 124, remarks in a note: 

 »that this species requires to be renamed, Gray's specific 

 »name being preoccupied by the common North- American 

 »Mouse, Mus hue opus , Rafinesque". But as the latter spe- 

 cies belongs to the group, named >yHesperomys''\ we will 

 retain Gray's name for the Indian Mouse in question. If, how- 

 ever, Alston objects to the name of this species, he should 

 also reject the name {Uromys) »rufescens'\ P. Z. S. L. 1877 , 

 p. 743 and adopt the specific name y>musavora" Pierson- 

 Ramsay, because under the name of Mus rufescens , a mouse 

 was already described by Gray , Ann. and Mag. Nat. Hist. 

 1837, p. 585.
