Masaharu Motokawa, Masashi Harada, Liang-Kong Lin, Kazuhiro Koyasu and Sh˘saku Hatteri (1997) The conventional, G-band, and C-band karyotypes of the gray shrew Crocidura attenuata from Taiwan were investigated. The autosomes consist of 3 meta-or subrnetacentrlc, 4 subtelocentric and 12 acrocentric pairs. The X and Y chromosomes are submetacentric and acrocentric, respectively.  The diploid chromosome number and fundamental  number were determined to be 40 and 56, respectively. This karyotype is different from that of a Thai specimen  previously recorded as C. attenuata.

Key words: Crocidura attenuata, Chromosomal evolution, Taxonomy, Soricidae.
