Blood serum samples from 33 red howler monkeys (Alouatta seniculus) were examined. Three different phenotypes were found and denominated A, B, and C. Four serums could not be classified because their transferrin apparently did not bind iron-59, possibly owing to saturation. A difference was observed in the electrophoretic migration and pattern of the transferrins in these monkeys compared with those of other primates.
