title: Stomatocytosis in a colony of captive squirrel monkeys (Saimiri sciureus).
abstract: Chronic stomatocytosis, which increased in severity as a function of the time that animals were held in captivity, was observed in a small colony of squirrel monkeys. The stomatocytosis was associated with increasing hematocrits possibly due to a change in packing characteristics of the erythrocytes rather than any overt changes in the erythrocyte mass. Reticulocytes remained at control levels throughout development of the stomatocytosis. The most probable cause of this alteration in erythrocyte shape distribution was dietary, but the exact etiology was not determined.
