Morphometry and aspects of breeding biology of Trachischium guentheri Boulenger, 1890 (Serpentes: Colubridae) in North Sikkim, Eastern Himalaya, India

Aspects of life history and morphometry of Günther’s oriental slender snake Trachischium guentheri (Boulenger, 1890) was studied along the Lachen and Lachung valleys of North Sikkim, Eastern Himalaya, India during 2003 – 2005. A total of 360 snakes were observed in 1026 man-hours of time constrained visual encounter surveys. Females were significantly larger (t = 3.19, df = 144, P < 0.01) and heavier (t = 3.04, df = 144, P < 0.01) than the males.
