"On the Inheritance of Black, Yellow, and Tortoise-Shell Color in Cats, with 
Special Reference to the Problem of the Tortoise-Shell Male": Seibutu, I (1), 
pp 1-7, Feb 1946, 
Formerly ‘the yellow and black color in cats was considered sex—linked, so 
when the gene of these two colors became heterozygous, the tri-color tortoise- 
shell appeared, According to the author, yellow alone is sex—liinked end black 
is caused by an autosomal gene, The sex ratio of yellow cats to black ones 
supports his theory.

"The Outline of a History of Japanese Mammalogy": Zool Mag, LIV (11), pp 442- 
453, Nov 1942, 
Brief summaries of the literature on classification, distribution, and ecology 
of Japanese mammals are given chronologically from 1868-1940, The author 
limits his scope to the main islands of Japan,

Islands" (with English resume): Bull Bioge Soc Jap, XIII (9), pp 59-64, 1 pl,

Tokudaia, nom, amend., is proposed for Acanthomys Tokuda, pre-occupied, so 
the Okinawa spinous rat becomes Tokudaia osimensis (Abi).

localities by the Yamashina Museum,

"Studies on the Murine Chromosomes, I Cylogical Investigations of Mice, Included 
in the Genus Mus" (in English): Jour Fac Sci Hok Imp Univ, VII (4), pp 305-380, 
Mar 1941, 
The chromosomes of Mus musculus, Mus molossinus, and Mus caroli, are described 
in detail, and analyzed and compared morphologically, In all three species 
the diploid number is 40, the haploid 20, The development of the sex chromo- 
somes followed from its first appearance to the metavhase of the firet maturé- 
tion division, In the primary and secondary oocytes of Mus musculus and Mug 
molossinus the chromosomes are not essentially different morphologically, and_ 
no sex difference in chiasma formation exists, Crosses between these two forms 
gives a completely fertile hybrid, whose courses of spermatogenesis and oogenesis 
proceed quite regularly, 

"Studies on the Murine Chromosomes II, Morphological Comparison of the Chromosomes 
between the Wild Form and the Domesticated Variety of Rattus norvegicus Berkenhout" 
(in English): Jour Fac Sci Hok Imp Univ, VIII (1), pp 31-43, Jan 1942, 
The chromosomes of wild rats from Hokkaido, Formosa, and Okinawa were compared 
with those of two strains of domesticated albino rats, No visible differences 
were found,

Five Species of Rattus" (in English): Jour Fac Sci Hok Imp Univ, 1X (1), pp 19-
