Ferania sieboldii

Bengal Mud Snake, (Siebold's Mud Snake, Siebold's Smooth Water Snake, Siebold's Water Snake)

Bengal-Schlammnatter

Bengalsk Muddersnog

1837 Homalopsis sieboldii Schlegel
Ferania sieboldi Gray 1842
Trigonurus sieboldi Duméril & Bibron 1854
Hypsirhina sieboldi Jan 1863
Enhydris sieboldi Mell 1929
1869 Feranioides jamnæticus Carlleyle (Murphy 2007)

Remarks: Restricted to Yamuna (Jumma?), Ganges, and Brahmaputra drainages in northern India and adjacent countries, according to Whitaker & Captain (2004) and Murphy (2007). Records from southern India (e.g., Goa: Pradhan 2008; Kerala: Easa & Ramachandran 2004; Palot & Radhakrishnan 2003; Smith 1943; Maharashtra: Gyi 1970; Smith 1943; Tamil Nadu: Daniels 2001; Aengals 2009) need confirmation, as they may represent misidentified dussumieri (Murphy 2007; Whitaker & Captain 2004). The only record from West Malaysia is based on a specimen which probably has wrong locality data (Murphy 2007).
Distribution: Bangladesh, India (Bihar, Delhi, Jharkhand, Madhya Pradesh, Mizoram, Nagaland, Odisha, Rajasthan, Uttar Pradesh, Uttarakhand, West Bengal), Myanmar, Nepal.
