The Galapagos rat, allied to common rat (M. decumanus), smaller size, tail longer, fur very long — that is the long silky hairs — the tarsus shorter, ears larger — the fur on the belly is totally white, to the base of ē hairs that in com. rat is invariably gray at the base — in the above characters it approaches to the Mus tectorum of Professor Savi but that species differs in its proportions.
Smaller species, very like some of the S. American forms.
