(1971) demonstrated elliptocytosis with transverse slitlike areas of decreased density in the red cells. This was accompanied by no hemolysis in vivo and red cell survival was normal. Male-to-male transmission was observed. The elliptical stomatocytosis described by Harrison et al. (1976) bears some similarities to the cases of Honig et al. (1971); however, their patients showed increased osmotic fragility whereas Honig's cases showed decreased osmotic fragility.
