This paper dealt with the measurement of some morphology indices in Manis petadactyla and Manis javanica. Measured variables included the body weight, the total body length, the length of head and body, the length of tail, the length of protruding rim of external ear, the length of hind feet, the length of middle claws of fore feet, the length of middle claws of hind feet, the number of rows of scales round mid-body, the number of single flank scales of edge tail. All variables measured were compared respectively between this 2 species. The results indicated that: (1) there were no significant differences in body weight and length of hind feet between this 2 species, but differences in the other variables were extremely significant. (2) The ratio of the length of middle claws of hind feet and fore feet in Manis pentadactyla was less than 1/2 (n=48), while Manis javanica was more than 1/2 (n=15); the length of protruding rim of external ear in Manis pentadactyla was over 10 mm (n=38), whereas Manis javanica was under 10 mm (n=13); the number of single flank scales of edge tail in Manis pentadactyla was not beyond 21 (n=65), and Manis javanica exceeded 21 (n=14). So the ratio of the length of middle claws of hind feet and fore feet, the length of protruding rim of external ear, and the number of single flank scales of edge tail should be regard as distinctive features and taxonomic indices between this 2 species. (3) The relationships between body weight (Y) and the total body length, the length of head and body, the length of tail (X) were positive correlation, and satisfied relation equation Y=aX^b.展开更多
