Abstract Based on both morphological and genetic evidence, we describe a new species of typhlopid snake from the dry zone of Sri Lanka, the first scolecophidian snake species to be described from Sri Lanka for nearly 75 years. Being the ninth member to the genus from the island, the new species can be distinguished from its congeners by the following combination of characteristics: small body (total length 94–131 mm, snout–vent length 91–128 mm, tail length 2.1–2.8 mm); 20 longitudinal body scale rows; narrow rostral, longer than wide in dorsal aspect (rostral width/rostral length 0.55–0.57), not extending to level of eye; frontal shield extending to upper level of eye; 322–352 middorsal scales (not including intercalary scales); 306–342 midventrals; divided nasal scale; first gland line across head straight, not extending to ocular level; second gland line convex, midpoint reaching midlevel of eye. We have provided molecular phylogenetic evidence to support its distinctiveness from the phenotypically similar I. braminus.

The Indian palm squirrel, Funambulus palmarum (Linnaeus, 1766) (Rodentia: Sciuridae) is known to feed on a wide range of plant items in the wild, including nuts, seeds, fruit, and bark, and will readily consume discarded food around human habitations. The species has been observed to prey opportunistically on insects such as termites and beetles. In addition, cannibalistic behaviour has also been recorded. Here we report the first observation of F. palmarum preying on spider egg sacs.
The baya weaver, Ploceus philippinus is a widespread resident bird throughout the Indian Subcontinent and is commonly found in open cultivation usually near water, in grasslands and scrublands. Its breeding season depends primarily on the southwest and northeast monsoon lasting from April to October. The species is particularly known for its unique nests built by males in colonies. The number of nests in each colony varies from 2–250. The nest is a retort-shaped structure with a long vertical entrance tube, densely woven out of strips of leaves of paddy, sugarcane or coarse grass, and blobs of mud are fixed inside the dome near the egg chamber. Moreover, the nests are usually built on branches of trees that overhang a water body which protects it from rats and other terrestrial animals. A complete baya weaver nest is a retort-shaped construction consisting of three parts: stalk, body, and entrance tube. Sharma (1995) classified 16 types of abnormal nests based on structural, orientation, and abnormalities.

The river tern (Sterna aurantia) is considered to be a globally vulnerable species. It is a native breeding resident of eastern and central Pakistan, Pan India (except the Trans-Himalayan region), Bangladesh, Myanmar, Thailand and Cambodia. It is a non-breeding resident in Nepal, southern Bhutan, Laos and Vietnam with vagrant records from Afghanistan and Iran. It breeds on sandy islands in freshwater lakes and rivers, and rarely estuaries.

Distribution and natural history notes on the herpetofauna of Ladakh, India

The Himalayas is the highest and youngest mountain range in the world. It provides unique habitat characteristics and is home to a unique assemblage of flora and fauna. There is very little information on the herpetofauna and their ecology in the trans-Himalayan region of Ladakh. Ladakh, located in an area of rain shadow, is characterized by extreme weather, climate, and terrain and relatively lower species richness. The region’s elevation ranges from 2,700 m to over 7,000 m a.s.l. and the annual precipitation is ~90–110 mm while the temperature ranges from -30 oC in winters to 30 oC in the summers.
