 In this animal the hallux could not be adducted beyond the position here shown, because the process for the tendon of the peroneus 



longus, on the proximal end of the hallux, abuts against the mesocuneiform and the second metatarsal.

 Hallux essentially as in Notharctm. 



3. Cebus hypoleucus. Amer. Mus. No. 14016. 

 The hallux can be fully adducted. 



4. Macacus nemestrinus. Amer. Mus. No. 14012.
