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

On the left side : 1 prae- and 1 postocular, on the right 1 prae- and 

 1 postocular. Temporals 1 + 1. 



All three specimens have 9 supralabials, 5th and 6th entering the eye. 



6. Dendrophis pictus var. striata Cohn. 



One specimen from Aur (Kumanis), Padang Highlands, III, 1914. 



15 rows of scales, ventrals 156, anal divided, subcaudals 150/150, 1 prae- 

 and 2 postoculars ; temporals 2 + 2. 



On the right side 8 supralabials, 4th and 5th entering the eye, on 

 the left side 9 supralabials (the third one being divided into two) 5th 

 and 6th entering the eye. 



One specimen from Muara Sako, Korintji, IX, 1915. 



15 rows of scales; ventrals 153, anal divided; subcaudals 127/127. 



1 prae- and 2 postoculars ; temporals 2 + 2. 



8 supralabials, 4th and 5th entering the eye. 



In both these two specimens the eye is much larger than in the 

 typical specimens of Dendrophis pictus, though not so large as in Den- 

 drophis formosus. Moreover the snout is shorter and broader, and the 

 chin-shields are somewhat smaller and broader. The keels on the ventral 

 shields begin directly behind the head. These characteristics, together 

 with the smaller number of the ventrals and the 8 supralabials, of which 

 the 4th and the 5th enter the eye, prove these two specimens to belong 

 to Dendrophis pictus var. striata Cohn, which variety might perhaps be 

 regarded as a distinct species. 



The . specimen from Aur shows very clearly the dark oblique bars 

 along the sides, especially on the fore part of the body; in the specimen 

 from Muara Sako these dark oblique bars are not so evident, though 

 clearly indicated. In both specimens a broad dark band runs on each 

 side of the head through the eye, these bands run over the nape where 

 they come very near one to another, only being separated by one row 

 of light coloured scales on the middle of the back. 



6. Dendrophis formosus Boie. 



Three specimens from Muara Sako, Korintji, X, 1915.
