Abstract: There are 7 species of pangolin in the world. 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 rimof 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 rimof 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 = a Xb.
