From
American Heritage Dictionary of the English Language, 5th Edition
The aye-aye, Chiromys (or Daubentonia) madagascariensis, is an animal with a superficial resemblance to a longhaired and dusky-coloured cat with unusually large eyes.
The aye-aye was discovered by Pierre Sonnerat in 1780, the specimen brought to Paris by that traveller being the only one known until 1860.
Till recently the aye-aye was regarded as representing a family by itself - the Chiromyidae; but the discovery that it resembles the other lemurs of Madagascar in the structure of the inner ear, and thus differs from all other members of the group, has led to the conclusion that it is best classed as a subfamily (Chiromyidae) of the Lemuridae.
Some of these creatures are highly specialized, while the curious aye-aye (Chirornys madagascariensis), an allied form, is one of the most remarkable animals known, forming a genus and family by itself.
