The distribution of melanotic melanocytes in the skin of the squirrel monkey ( Saimiri sciurea ) is similar to that of the Cercopithecoidea studied. However, the arrangement of hair follicles, the number of hairs in the hair groups, and the presence of alkaline phosphatase in the peripheries of sebaceous acini resemble more those of the tree shrew ( Tupaia glis ) and owl monkey ( Aötus trivirgatus ). The absence of eccrine sweat glands from the hairy skin and the aggregation of apocrine sweat glands in the chest in the squirrel monkey resemble those found in the blackcollared tamarin ( Tamarinus nigricollis ) and owl monkey. The most outstanding peculiarities of the skin of the squirrel monkey are: (1) the presence of butyrylcholinesterase‐rich papillary nerve end‐organs in the friction surfaces and (2) hair follicle nerve end‐organs which are surrounded by melanotic melanocytes.
