CHAPTER VIII. 
Apes, Monkeys, and Lemurs,— concluded. 
The Tarsier and the Aye-Aye. 
These two strange creatures, although sufficiently nearly related to the lemurs to 
be included in the same great group, yet differ so markedly, not only from the 
lemurs, but likewise from each other, as to make it necessary to refer them to two 
distinct families —Tarsiidce and Chiromyidce. This gives us, for the first time, 
instances of families represented not only by a single genus, but by a single 
species.
