Summary. The authors describe an assumed but hitherto undiscovered variant of incomplete ‘Bombay’ phenotype, designated as B h , with partial suppression of the B antigen. The erythrocytes contain a very weak B antigen, at quantitative level B 20 ; they are H‐negative and Le a ‐positive. The serum contains anti‐A, anti‐B and anti‐H antibodies. The patient is a secretor of Le a and a non‐secretor of ABH. The quantitative and immunogenetic properties of the variant are discussed. It is supposed that the variant is the effect of the gene combinations H x h , or H x H x at the Hh locus. We wish to thank the physicians attending the patient K. M., Dr. V. K luge from Tatranská Kotlina and Dr. L. D ráč ; from Vel'ký. Šariš for assistance in obtaining the necessary blood samples.
