Abstract
We report on a topotypical specimen of the spot-tailed pit viper Trimeresurus erythrurus recorded from Sunderbans in India and a distant, southerly, range extension from Kakinada mangroves, based on preserved (n= 1, seen in 2019) and live uncollected (n= 2; seen in 2014) specimens, respectively. The specimens (n= 3) share the following characteristics: verdant green dorsum, yellow iris, white ventrolateral stripes in males, 23 midbody scale rows, 161–172 ventrals, 61–76 subcaudals, and reddish tail tip. Drawing on the published records, its apparent rarity within its type locality and lack of records from the Circar Coast of India, our study significantly adds to the knowledge of the distribution and morphology of this species. Being a medically important venomous snake, its presence in the Godavari mangrove basin calls for wider dissemination of this information among medical practitioners, in addition to fundamental researchers like academics and herpetologists.

Abstract
The present study was conducted to determine the diversity of mammalian species from a peri-urban coal mining region of West Bengal for almost three years from September 2017 to August 2020. The survey was done on the basis of direct sightings, extensive searches, detection and identification of indirect mammalian signs such as pug marks and droppings, opportunistic sightings and road-kill incidents. Secondary information from previous literature and information from local people, citizen scientists and Forest Department were also included in the study. A total of 20 mammals belonging to 9 orders, 15 families and 20 genera were observed from 31 locations during the present study and 6 species belonging to two orders, three families and four genera which were previously reported from the present study location but not observed during this study were also included in the list. Two endangered species, Asian Elephant Elephas maximus and Indian Pangolin Manis crassicaudata, were observed from the present study location within the study period. Based on the habitat types, the maximum number of species was observed from the Human Habitation (HH) areas whereas the least number of species was noted from the Riverside Zones (RS). Proportion of the different habitat types for each mammalian species found in the present study and also obtained from literature depicted that Asian House Shrew Suncus murinus, Asian Palm Squirrel Funambulus pennant and Indian Pygmy Pipistrelle Pipistrellus mimus were among the most abundant mammals in the study area. Golden Jackal Canis aureus was observed from a wide variety of habitat types whereas the two varieties of civets were only observed from the riverside areas. Principle Component Analysis between species and habitat type indicated that the Bengal Fox Vulpes bengalensis and the Black-naped Hare Lepus nigricollis were only associated with the grasslands. The Hanuman Langur Semnopithecus entellus and other small rodent species were generally found in the human habitation areas. Various threats like habitat destruction, habitat degradation and hunting posed the major problems in the present study location.
