The genus Pendrophis as now understood comprises at least 11 

 species, distributed in Southern Asia between India and Indo- 

 China, through the Malayan Archipelago to Eastern Australia. 

 Of these species 6 occur within our Indian limits, viz., (1) pictus 

 (Eastern Bengal, Eastern Himalayas, Irrawaddy-Salween basin, 

 and Tenasserim and further East to Indo-China), (2) grandoculis 

 (Hills of Southern India), (3) bifrenalis (Ceylon and Travancore 

 Hills, Ferguson), (4) caudolineatus (Ceylon), (5) and (6) gorei,* 

 and proarehos-\ (Brahmaputra basin). 



Until 1890 several other species were included which have now 

 been grouped together on characters affecting dentition under a 

 separate genus called Pendrelaphis by Mr. Boulenger. This genus 

 includes 3 species found in Indian Territory, viz., (1) tristis (Penin- 

 sular India, Eastern Himalayas, Brahmaputra Valley and Ceylon) ; 

 (2) subomlaris (Hills of Upper Burma) ; and (3) biloreatus J 

 (Brahmaputra Basin).
