Description

Comparative Morphology of the Pelvis and Hind Limb of Japanese Muroidea. II. Characteristics from the view point of ecology and systematics. Yukibumi KANEKO (Zoological Institute, Faculty of Science, Kyoto University) Zool. Mag. 78 : 163-173 (1969). The results obtained by the present investigation may be summarised as follows : 1) The degree of the development of tuberosity, crest and ridge of the pelvis and hind limb seemed to be correlated with that of fossorial life of some animals. 2) Of all the species examined in the present study, the sexual differences in length and width of pubis and obturator foramen were apparently observed. These differences would be derived from the functional difference of the animals of each sex. 3) The severance of pubic symphysis in female animal was observed in all the species of Microtinae used in the present investigation. While, In Murinae, it was found only in the case of Mus molossinus var. 4) For the explanation on the process of reduction and severance of pubic symphysis, the interpretations given by Chapman (1919) and Rensch (1959) seemed to be most reliable. 5) If it would be assumable that the degree of the difference observed in Murinae represents a general tendency of sexual difference of the pelvis, the degree of the same difference found in Microtinae could be considered as a specialized one which might be attributed to the phylogenic deviation.
