3. Polyodonthophis geminatus (Boie). 



One specimen from Tanangtalu, Ophir districts, Padang Highlands, 1915. 



Yentrals 148, anal divided, subcaudals 95/95, scales in 17 rows. One 

 prae- and 2 postoculars; 8 supralabials on the right side, the 3rd, 4*h 

 and 5th entering the eye; on the left side 9 supralabials, the 4th ? 5th 

 and 6th entering the eye. 



Upper part of body dark coloured, on each side a bluish grey dorsal 

 stripe with a series of dark spots, reaching till on the beginning of the 

 tail. Head reddish brown with small yellow dark rimmed spots. Behind 

 the underpart of the eye a ligth band bordered by a dark line. In colo- 

 ration our specimen shows much resemblance with Polyodonthophis (Eci- 

 cognathiis) javanicus Blkr. 



4. Pseudoxenodon Jacobsonii nov. spec. 



One specimen, from Serapai, Korintji, VII, 1915, 



Yentrals 145, anal divided, subcaudals 37/37, 19 rows of scales. Rostral 

 nearly twice as broad as deep, visible from above. Praefrontals one and 

 a half as long as internasals, nearly as long as the frontal; frontal hexa- 

 gonal with very obtuse anterior and posterior angles, as broad as long, 

 much shorter than its distance from the tip of the snout, shorter than 

 the parietals; loreal more deep than long (on the left side of our speci- 

 men 2 superposed loreals; one praeocular more than twice as high as 

 broad, 3 postoculars; temporals 2 + 2; seven upper labials, 3rd and 4th 

 entering the eye ; four lower labials in contact with the anterior chin- 

 shields, latter almost as long as the posterior pair. 



Scales in 19 rows, those of the three middle series keeled, the others 

 smooth, on the flanks disposed obliquely. 



Greyish above; the lower parts in the anterior half; yellowish with 

 irregular dark spots increase in the posterior half of the body, so that 

 at the end of the body and the tail the underparts are of a dark colour. 



This species is closely allied to Pseudoxenodon inornatus Boie from 

 which it differs in the greater number of ventrals, in having only one 

 praeocular, and in the form of the frontal which in our species is. as 

 broad as long, and almost pentagonal because of the obtuse anterior angle. 



5. Dendrophis pictus (Gmelin). 



One specimen from Buo, Padang Highlands, III, 1914. 



15 rows of scales, ventrals 167, anal divided, subcaudals 126/126.
