Despite its recognition since the early 1900s, the agamid lizard Pseudocalotes austeniana remains known based on 3 vouchered specimens only from the East Himalaya, and little is known about its general biology. During herpetological surveys of Tibet, China, we collected 3 specimens of P. austeniana from Medog County, southeastern Tibet, including the first juvenile specimen ever vouchered. We provide a detailed description based on new material of this enigmatic species, report on a range extension of 400 km northeastward from its type locality, its ontogenetic shift, and clutch size.

Little is known about the worm-eating snakes of the genus Trachischium in the East Himalaya due to their secretive nature. To date, only T. monticola and T. tenuiceps are recorded from China, and the former species was recorded based on historical literature without vouchered information. In addition, a questionable record of T. guentheri in Tibet, China exists in literature, but no one has yet confirmed this distribution record. Here we confirm the distribution of T. guentheri in southeastern Tibet, China based on a newly collected specimen, and provide the first detailed description of T. monticola, including the first description of its hemipenial morphology, based on newly collected Tibetan specimens. Lastly, we provide a diagnostic key to the three Chinese species, and discuss the general distribution patterns of the genus in the Trans-Himalayan Region.

Western developed countries encountered the problem of "welfare dependency" in the construction process of social assistance system. From our urban subsistence allowances system, this thesis Demonstrates that the "welfare dependency" problem in the context of western country does not exist in China's urban subsistence allo wances system ， but "welfare dependency" problem with Chinese characteristics. This thesis is trying to make an institutional analysis about the causes of it, which main ly contains the balance subsidy system ,the "superposition of welfare" in the subsistence allo wances system, subsid ies given according to fam ily and relatively higher benefit replacement rate, and then proposin g to implement a negative income tax system, establishin g an assistance system with clear division of responsib ilities, changin g the solution to household-based calculation methods and reducing the benefit replacement rate.

In the last paragraph of page 16, we lost a species, Dendrelaphis subocularis from China, and this species was also lost in the key of page 17. The correction as below: Currently, six species of the genus Dendrelaphis are known from China, including D. biloreatus from Tibet; the D. cyanochloris complex from Tibet, Hainan and Yunnan; D. hollinrakei from Hong Kong; D. cf. pictus from Guangdong, Guangxi, Hainan and Yunnan; D. subocularis and D. vogeli from Yunnan. An updated diagnostic key of the six known species in China is provided below.
