The specific name, cantoris, is in honor of Danish zoologist Theodore Edward Cantor.

[3] E. cantoris is found in the Himalayas in Bhutan, India (Assam, Darjeeling, Sikkim), Myanmar, and Nepal.

[2] The preferred natural habitat of E. cantoris is mountain forest at elevations of 1,000–2,300 m (3,300–7,500 ft).

[4] E. cantoris is a large species, and may grow to a total length (including tail) of almost 2 m (6.6 ft).

Dorsally, it has a brownish ground color, which is overlaid by a series of squarish dark brown blotches.
