Sub-family Galaginse, contains only the genus Galago (14 sp.), 
which is confined to the African continent, ranging from Senegal 
and Fernando Po to Zanzibar and Natal.

The curious Tarsius spectrum, which constitutes this family, 
inhabits Sumatra, Banca, and Borneo, and is also found in some 
parts of Celebes, which would bring it into the Australian 
region ; but this island is altogether so anomalous that we can 
only consider its productions to have somewhat more affinity 
with the Australian than the Oriental region, but hardly to 
belong to either. The Tarsier is a small, long-tailed, nocturnal 
animal, of curious structure and appearance ; and it forms the only 
link of connection with the next family, which it resembles 
in the extraordinary development of the toes, one of which is 
much larger and more slender than the rest. (Plate VIII., vol. 
i. p. 337.)

The Aye-aye, ( Chiromys ), the sole representative of this family, 
is confined to the island of Madagascar. It was for a long 
time very imperfectly known, and was supposed to belong to 
the Rodentia ; but it has now been ascertained to be an ex- 
ceedingly specialized form of the Lemuroid type, and must be 
considered to be one of the most extraordinary of the mammalia 
now inhabiting the globe. (Plate VI., vol. i., p. 278.)
