Scientific Name: Xylophis perroteti (Duméril, Bibron & Duméril, 1854)
Common Name(s):
English Striped Narrow-headed Snake, Perrotet's Mountain Snake
Geophis microcephalus (Günther, 1858)
Platypteryx perroteti Duméril, Bibron & Duméril, 1854
Rhabdosoma microcephalum Günther, 1858
Taxonomic Notes: Xylophis perroteti was first described as new species by Duméril, Bibron and Duméril in 1854 as Platypteryx perroteti from the Western Ghats based on specimens from Nilgiri Hills, Tamil Nadu. This species is superficially the most distinctive species in the genus, having 13 as opposed to 15 scale rows and being much larger (Whitaker and Captain 2004, Gower and Winkler 2007). It is suggested that a reassessment of the taxonomic status of X. perroteti is required (Gower and Winkler 2007).
