1. A hybrid Parus varius × P. atricapillus (montanus) obtained in Yamagata, September, 1966, has been kept alive untill May, 1969. It is intermediate in plumage and had a voice of varius though finer. Five of this hybrid are known in Japanese literature between 1830 and 1937.
2. A male Emberiza spodocephala captured in Tokyo in November, 1964 and kept alive untill December, 1967, was of Japanese personata type but was distinctly greyer above and less yellowish below. It may not be a variant but may have come from some northern population.
