THE GIBRALTAR MONKEY 
communicated to the Zoological Society, the fact that 
no less than thirty of these tailless apes had been seen 
in one herd. The interest of the presence of these apes 
in Europe seems on the whole to have been allowed 
to overbalance the objections felt towards them on 
account of their depredations in gardens. But it is not 
quite certain how far the interest is a genuine one, 
that is to say, how far the Macacus inuus is a really 
indigenous inhabitant of African Spain, and whether 
it was not at one time deliberately introduced there 
and allowed to run wild. Be this as it may, the ape 
proved capable of establishing itself in the more in- 
accessible parts of “the Rock.” Macacus inuus belongs 
to a genus of monkeys, which is, like the baboon, a 
member of the Catarrhine subdivision. So that it is 
unnecessary to recapitulate the characters which, being 
a Catarrhine, it shares with the baboon. These monkeys 
are, with the exception of the species which we are here 
considering, entirely Asiatic in range; and many 
members of the genus are familiar enough, for a large 
assortment is always on view in the monkey house 
and the outside monkey cages at the Zoo. The Gib- 
raltar monkey is also exceptional in that it has no tail, 
though in many of its allies—for instance in the Tcheli 
monkey, that thick-furred inhabitant of the Yung Ling 
mountains of Northern China—the tail is plainly on 
the way towards disappearance. On the other hand the 
common bonnet monkey and Rhesus monkey have 
longish tails. There are altogether some fifteen or 
sixteen species of macaques. The Barbary or Gibraltar 
ape has a certain historical interest in that it appears 
to have been the monkey dissected and studied by 
Galen the Greek physician.
