 F.M.P., p. 157. 



One 9 immature. Padang, Gunong Tahan. 

 Ventrals 164. Caudals 16. 



Psammodynastes pulverulentus (Boie) . 



Three adults. Padang, Gunong Tahan and Kuala 

 Teku. 



Scales 17.17.15., ventrals $ 170, $ 173, 174. Caudals 

 $ 61, 9 57,. 60. 



This species and Lachesis sumatrana are the only 

 species other than very rare on Gunong Tahan. Both 

 are common there as on other high mountains in the 

 Malay Peninsula. 



Doliophis intestinalis (Luar.). 



F.M.P., p. 206. 



Two examples from Kuala Tahan and Kuala Teku. 



No. 5902, juv. V. 250., C. 26; No. 5903, 9 V. 242. C. 21. 



Colour (in spirit). Jet black above and on the sides, 

 with 3 narrow white lines, the vertebral (not bifurcated) 

 starting from the neck and extending to the tip of the 

 tail, the laterals occupying the upper half of the outer 

 row of scales and the lower half of the row next and 

 extending to the vent. Belly with broad transverse bars 

 of black and white; tail below orange, with two narrow 

 bars. Top of head brown mottled black. 



Trimeresurus gramineus (Shaw). 



Lachesis gramineus, F.M.P., p. 17. 



Two specimens from Fraser's Hill. Green above, 

 pale blue below ; outer row of scales white in the 

 upper half, dull red in the lower. This red pigment 

 in the flank band is common in examples from farther 

 north (N. Siam), but does not appear to have been 

 recorded before from the Peninsula. It does not occur 

 in specimens from Bangkok and the surrounding country 

 where this snake is common. 



Boulenger's statement (p. 217) that this species is 

 without distinct canthus rostralis is not borne out in 

 specimens I have examined. In most adults it is well 

 marked.
