Mains et pieds des primates simiens

The 1st ray in humans is nearly as long as the 2nd toe, the other toes being very short. The 1st ray of the hallux of all monkeys was always longer than the ray of the thumb, but shorter than the hallux of humans. The other metatarsi of little monkeys were similar to those in humans, except for the platyrrhinii which had a shorter 2nd metatarsus. The lateral toes, which were much longer than in humans, were very similar to fingers though slightly longer, except for platyrrhinii with much longer toes. The big monkeys had very short metatarsi and slightly smaller lateral toes than humans.
