SYNOPSIS. A spontaneous albino mutant of the red heterotrichous ciliate Blepharisma intermedium has been isolated and studied. In addition to its apparent lack of pigment, the albino differs from the parental stock in its manner and frequency of conjugation, high incidence of cannibalism and reduced intensity of micronuclear stainability. The conjugation pattern of the albino is compared to that of the pigmented form as described in the literature. The albinistic character thus far has bred true. Alcoholic extracts of the albino yielded only a trace of pigment. Absorption spectra of alcoholic extracts of the pigmented, the artificially bleached, and the albino organisms were compared.As far as is known, no conjugation or other type of internal nuclear reorganization was observed preceding the phenotypic expression of the mutation; this raises several questions pertaining to the site of mutation and means of its expression. These questions are discussed.
