hi matthew,
I think our hk reptiles book did'nt update the name.
Calamaria septentrionalis should be
Cylindrophis ruffus,(Laurenti, 1768). Two species of
Cylindrophis and two species of
Anomochilus are known from Borneo. The two in genus
Anomochilus do not have 'red tail'. I suppose the snake is possibily the
Cylindrophis lineatus,Blanford,1881, but i don't have more references for the ID. In Stuebing, 1994: 967, "
Cylindrophis lineatus in the sarawak museum are indistingishable from
C. rufus taken from the same collection."
