Leiothrix lutea is a kind of small singing bird of the order Passeriformes of the family Timaliidae. The skeletal system of Leiothrix lutea has been described and measured based on 30 (9 ♂ ,21 ♀ ) specimens. It's characterized by the following: the skull is thin and light with a big cranial cavity; eye socket is large and interorbital distance is small. Two open notches are located symmetrically at lateral sides of caudal sternum which has well developed keel. The clavicle bears a lamellar interclavicle at the end. There are 6 ～ 7 protuberances outboard of the ulna. The trochleae of metatarsal Ⅱ is large and strong, and there is a crack between the trochle of metatarsal Ⅱ and tarsometatarsus. The phalange of hind toe is long and strong. The ratio of sternum's length and the depth ( L/ H) and width and the depth (W/H) are 2.25 and 1.25 respectively. Statistic analysis of the data show that there are significant differences in the transverse diameter and the vertical diameter of foramen magnum and the length of pubis between male and female. All these facts indicate that the skeleton structure of Leiothrix lutea conforms to their ecological habits.
