What is a group of tarsiers called?

According to both my Walker's 'Mammals of the World' and the PRO Encyclopaedia of Mammals, all primate young are known as 'babies' and 'infants.

The Tarsier is of course a primate, but a very rare and small one. Only 3 species are known, from the Phillipines, Borneo, Sulawesi and Sumatra.
