 Scales in 13 rows; ventrals 262, anal entire, subcaudals 46/46. 

 32. Doliophis intestinalis (Laur.) var. sumatranus Lidth. 



Two specimens: one from Biinbo Pengadang (Lebong), Benkulen, 

 VI, 1916, the other without exact indication of locality. 



a. Scales in 13 rows; ventrals 225, anal entire, subcaudals 27/27. 



b. Scales in 13 rows; ventrals 216, anal entire, subcaudals 28/28. 



Both specimens very much agree in coloration with the typical spe- 

 cimen of Doliophis sumatranus Lidth, described in Max "Weber's Zoolo- 

 gische Ergebnisse I p. 190, but differ from it in the arrangement of the 

 dark crossbars on the belly, as in the typical specimen the first of these 

 crossbars occurs on the 73rd ventral, whilst in the present specimen these 

 dark bars do occur directly behind the head. 



Both specimens have 6 upper labials, the third and the fourth entering 

 the eye, one prae- and two postoculars, the temporals being 1 + 2 (and 

 not 1+1 as was erronously stated in the above mentioned description 

 of Elaps sumatranus). 



33. Amblycephalus malaccanus (Ptrs.). 



Two specimens from Balun (Muara Labu), Padang Highlands, VII,

«. Scales in 15 rows; ventrals 167, anal entire, subcaudals 41/41. 



b. Scales in 15 rows; ventrals 166, anal entire, subcaudals 47/47. 



One specimen from Benkulen, leg. W. Groeneveldt, Oct. 1918. 



Scales in 15 rows; ventrals 162, anal entire, subcaudals 31/31. 



According to a note from the collector this specimen had the upper 

 parts light gray with a rosy tint. 



34. Lachesis sumatranus (Raffles.). 



One specimen from Muara Saku, Korintji, IX, 1915 (nom. indig. 

 ula tuon). 



Scales in 21 rows; ventrals 185, anal entire, subcaudals 58/58. 



One specimen from Balun (Muara Labu), Padang Highlands, VIII, 1914. 



Scales in 21 rows; ventrals 189, anal entire, subcaudals 57/57. 



In the specimen from Balun the subocular is in contact with the 3rd, 

 4th and 5th upperlabial ; the same arrangement of the supralabials is to 

 be seen on the left side of the specimen from Korintji, but in that spe- 

 cimen the 3rd upper labial of the right side is horizontally, divided into 

 two parts ; an upper and a lower one, the lower one bordering the mouth,
