" This species is allied to the Mus Cahirinus of Geoflfroy; it is, 

 however, not so large ; and although the hairs are flat and bristle- 

 like, they are less harsh than those of the North African species ; it 

 also differs in its colouring."

Obs. Mr. J. E. Gray believes this bird to be from Demerara, or 

 the Brazils ; the specimen is in the collection at the British Museum, 

 and so far as I am aware is unique.
