60 Trimeresurus trigonocephaly. 



Green, belly paler. Black, network on head, band from 

 eye to angle of mouth, vertebral band emitting lateral streaks. 

 Yellow, border of vertebral band, spots on lateral streaks, 

 tinge on lateral scales, broad margins to ventrals. 



Section X. 

 Belly brilliantly coloured. 



42 Callophis trimaculatus. 

 Belly rich mauve graduating to pale yellow, increasing to 

 orange crimson just before vent ; behind deep velvety black, 

 then pearly gray to tip of tail. Golden gray. Black, head, a 

 spot on apex of each scale, two rings on tail. Yellow, two

 caudal rings. 



HABITS. 



A = 24 Zamenis mucosus. 



Non-poisonous, diurnal, terrestrial or subarboreal, feed- 

 ing principally on mammals and birds. Oviparous. 3, 

 18, 19, 24, 25, 26. 



|J - 30 Tropidonotus stolatus. 



As in a, but freely entering water. Prey, frogs and 

 fish. 30,31,33. 



C = 15 Lycodon aulicus. 



Ground-snakes, feeding almost exclusively on skinks. 

 15, 16. 



D = 27 Dendrophis pictus. 



Diurnal tree-snakes. Prey, small lizards and frogs. I 

 imagine 37 Dryophis mycterizans differs but little in 

 habits. Both species may be seen in bushes and creepers 

 in bright sunshine. D. pulverulentus is a rare snake, 

 and nothing is known of its habits. 27, 28, 37, 39.
