We need a name for those ‘prosimians’ that are not tarsiers. ‘Strepsirrhines’ has become customary. It means ‘split nostril’ (literally twisted nose). It is a slightly confusing name. All it means is that the nostril is shaped like a dog’s. The rest of the primates, including us, are haplorhines (simple nose: our nostrils are each just a simple hole).
