Shenbrot, in litt., 2003; Ma et al., 1987 ; Mi et al., 1990 ; Qin, 1991 ; Wang, 2003 ; Zhang et al., 1997 , and Zhou et al., 1985 ); Mongolia ; S Tuviskaya Oblast, and E Kazakhstan (see Ilchenko and Volodin, 1992 , and Sokolov and Shenbrot, 1988 ). Shenbrot et al. (1995) provide overall distribution map. Conservation: IUCN – Vulnerable. Discussion: A morphometric study by Sokolov and Shenbrot (1988) indicated that the Kazakhstan population falls within the range of intraspecific variation for C. paradoxus , and is not a separate species as was suggested by Gromov and Baranova (1981) . For detailed habitat data see Naumov and Lobachev (1975) . Reviewed by Gromov and Erbajeva (1995) and Shenbrot et al. (1995) .
