Fam. COLUBRIDAE. 



Subfamily Coijtbrinae;. 



22. Trachischium monticola (Cantor). 



Boulenger, Fauna, p. 286, 



A common snake in the hills of Assam, less abundant in the 

 E. Himalayas. Ten specimens were taken by the 32nd Sikh 

 Pioneers while road-making in the neighbourhood of Upper Rotung 

 (alt. ca. 2,000 ft.) in January. Capt. de Courcy took another in 

 the Sirpo valley near Renging. 



23. Blythia reticulata (Blyth). 



Boulenger, op. cit., p. 287, fig. 92. 



Three specimens were taken at Upper Renging, at Upper 

 Rotung and in the Sirpo valle}^ near Renging. The species, which 

 is the only one in the genus, is characteristicallj^ Assamese. Fresh 

 adult specimens are almost black in colour with a beautiful deep- 

 blue iridescence, the pale markings becoming inconspicuous with 

 age. 



Aproaspidops, gen. nov. 



This new genus is allied to Trirhinopholis and Plagiopholis, 

 Boulenger. both of which are only known from Burma. It thus 

 belongs to a peculiar little group of monotypic genera that includes 

 Blythia and the two just mentioned and inhabits hilly country in 

 Burma and Assam. Aproaspidops can be recognized easily by the 

 fact that there is an azygous shield between the rostral and the 

 supranasals and also a small postnasal on each side. There is no 

 praeocular and no loreal, unless the latter name should be applied 

 to the small scale I have called the postnasal,
