Ptyas doriae is a rare snake in northeastern India, Myanmar and southern China. The original description and subsequent accounts of this species were all very brief. We studied most of the available specimens of this species and on this basis we provide a detailed redescription of the species. We give an account of intrapopulational variation in scalation characters and colouration and we also report on a previously undescribed colour morph from Manipur, India. We have examined the holotype of Ptyas hamptoni and found that characters used to distinguish it from P. doriae are inadequate and therefore we herein synonymize the former with the latter species. We also predict the potential distribution of P. doriae by using Maximum Entropy modeling.

The three mammalian orders Chiroptera, Rodentia, and Eulipotyphla constitute the bulk of small mammalian species. In spite of their diversity, numerical preponderance, and widespread distribution, they are the least explored mammals with serious information gap on the diversity and distribution especially in the context of northeastern India. To partially fill this crucial information gap, we conducted two extensive field surveys covering nine districts of Manipur state during 2019 and 2021 resulting in the collection of 62 examples of these groups. Besides, 12 additional examples of bats and shrews from Manipur deposited at the North Eastern Regional Centre (NERC) of ZSI, Shillong and two specimens of rodents deposited in Manipur University  in recent times were also examined. Based on these voucher records and field evidences, we report the presence of 38 species of small mammals from the state including 27 species of bats, 10 species of rodents and one species of shrew. Out of these, 12 species of bats have been recorded for the first time from the state. It is expected that the present inventory will expand with further surveys as fossorial rodents and shrews were not adequately sampled during the present studies.

Specimen based records of five species from Manipur state namely Rhinolophus sinicus, R. yunanensis, Kerivoula picta, Myotis muricola and Miniopterus magnater is presented. The mensural data of the examined specimens from Manipur and comparative data from India and Nepal are also provided. With the current additions, the bat inventory of Manipur stands at 17 species. This also highlights the paucity of information on the bat species diversity and distribution of bat fauna in the state and calls for extensive field based studies.
