Well, the BOOK says Gibraltar Monkey! Acorcing to Wikipedia...

Most of its upper area is covered by a nature reserve, which is home to around 250 Barbary Macaques, the only wild monkeys in Europe.

So 2 out of 3 sources call them monkeys... and the DO live in GIBRALTAR.... so I deduce they are Monkeys from Gibraltar OR Gibralter Monkeys !

I rest my case Mr. KnitPicker! Next, I guess you'll dispute the grade huh?
