ships, especially the Norway rat, also called
brown rat,
(
Rattus norvegicus formerly
Mus decumanus), the black
rat (
Rattus rattus formerly
Mus rattus), and the roof
rat (formerly
Mus Alexandrinus, now included in

Note:
“It so chanced that, not long after the accession of
the house of Hanover, some of the brown, that is the
German or Norway, rats, were first brought over to this
country (in some timber as is said); and being much
stronger than the black, or, till then, the common,
rats, they in many places quite extirpated the latter.
The word (both the noun and the verb to rat) was first,
as we have seen, leveled at the converts to the
government of George the First, but has by degrees
obtained a wider meaning, and come to be applied to any
sudden and mercenary change in politics.” --Lord
Mahon.
