1) Most of 162 hybrids showed the normal phenotypic expression in the fermentation of galactose and α-methyl flucoside, and in the film formation. But some irregularities in genetic analysis of a few hybrids can not for the present be expleined.2) Respiratory deficiency of haploid strains occurred at a very high frequency (ca. 14 per cent of stock cultures) during 8 months' preservat on. This deficiency was found in hybrids, of which either one or both parent haploids were also respirationally dificient.3) It is presumable from crossing and genetic analysis that the respirtionally deficient mutation might be due to the decrease or loss of cytoplasmic particles concerned with the respiratory enzymes rather than genic change.4) During the preservation of hybrids the decerase of their sporulating ability might be closely related to the decrease or loss of cytoplasmic particles.
