Saliva, serum and erythrocytes from 25 M. radiata and 18 P. entellus monkeys were tested for human type A, B, O and M, N blood factors. Blood group A was found in 44% and B in 56% of M. radiata monkeys. Erythrocytes of M. radiata monkeys showed the presence of only M antigen. Blood group AB was in 11.2% and B in 88.8% of P. entellus. Erythrocytes of all P. entellus had M and N antigens. Erythrocytes of human blood groups A, AB, B, O and of both types of monkeys were tested with lectins from Phaseolus lunatus and P. vulgaris. The monkey cells were agglutinated by lectins of P. lunatus and P. vulgaris. The titer of the lectin from P. lunatus was 320-fold lower with M. radiata cells and 8-32-fold lower with P. entellus cells as compared to the human type A or AB cells. The titer of P. vulgaris lectin displayed 2-8 fold lower titer with human cells as compared with the monkey cells. Trypsinization of the erythrocytes of human and monkeys increased titer of lectins. In the P. lunatus lectin there seemed to be 2 components; 1 which reacted with human and monkey cells, and the other reacting with human cells only.
